journal = {International Journal of Electronic Commerce},
year = {2012},
abstract = {Recently Internet auction sites have begun to compete in emotions
by advertising the fun and excitement that bidders may experience during auction
participation. The implicit conjecture inherent in these advertisements is that
consumers derive a hedonic value from auction participation that makes exciting
auctions more attractive and possibly induces bidders to stay active longer
in the auction. We test this conjecture in a controlled economic laboratory
experiment in which we also measure bidders’ physiological arousal in terms
of heart rate and skin conductivity as proxies for their excitement during auction
participation. In particular, we conduct a series of descending price (Dutch)
auctions with different clock speeds and find that in fast Dutch auctions bidders
(i) are more excited and (ii) stay longer in the bidding process. Moreover,
the unpleasant event of losing a Dutch auction is experienced more strongly
than the rewarding event of winning. As our results show that bidders’ excitement
is directly reflected in final prices, Internet auction sites should carefully
consider how the emotions elicited on their platforms affect bidding behavior.}}

are the basis for households to better monitor electricity consumption and to
actively control loads in private homes. Demand side management (DSM) can be
adopted to private households. We present a simulation model that generates
household load profiles under flat tariffs and simulates changes in these profiles
when households are equipped with smart appliances and face time-based electricity
prices.



We investigate the impact of smart appliances and variable prices on electricity
bills of a household. We show that for households the savings from equipping
them with smart appliances are moderate compared to the required investment.
This finding is quite robust with respect to variation of tariff price spreads
and to different types of appliance utilization patterns.



Finally, our results indicate that electric utilities may face new demand peaks
when day-ahead hourly prices are applied. However, a considerable amount of
residential load is available for shifting, which is interesting for the utilities
to balance demand and supply.}}

in both traditional and Internet auctions. In order to gain a better understanding
of its causes, we develop a conceptual framework to analyze emotions in auctions,
which is based on an exhaustive literature review. The framework integrates
rational calculus with emotional aspects and suggests that emotional processing
is triggered at three different stages of an auction: First, the economic
environment can affect a bidder’s level of perceived competition and thus
influence the bidding strategy prior to the auction. Second, auction events
may have ramifications on the bidder's emotional state during the auction due
to previous investments or perceived ownership. Third, past auction outcomes
may impact future bidding behavior through emotions such as the joy of winning
or loser regret. Auction fever, eventually, is a phenomenon that results from
the interplay of these emotional processes and causes a bidder to deviate from
an initially chosen bidding strategy.}}

abstract = {Autonomous agents are widely applied to automate interactions in
robotics, e.g. for selling and purchasing goods on eBay, and in financial markets,
e.g. in the form of quote machines and algorithmic traders. Current research
investigates efficient economic mechanisms that fully automate the provisioning
and usage processes of Grid-based services. On the one hand, consumers want
to allocate resources on demand for their various applications, e.g. data sharing,
stream processing, email, business applications and simulations. On the other
hand, providers of Grid services want to govern business policies to meet their
utilization and profit goals. The above-mentioned processes are not manually
manageable, however, because decisions need to be taken within milliseconds.
Therefore, such processes have to be automated to minimize human interactions.
Hence, market mechanisms and strategic behavior play important roles when it
comes to achieving automated and efficient allocation of Grid services. The
paper begins by presenting a framework for automated bidding, providing a
methodology for the design and implementation of configurable bidding strategies.
Second, it presents a novel bidding strategy based on a reinforcement learning
technique. This strategy is designed to automate the bid generation processes
of consumers and providers in various market mechanisms. Third, the behavior
and convergence of the strategy is evaluated in a centralized Continuous Double
Auction and a decentralized on-line machine scheduling mechanism against selected
benchmark bidding strategies. Fourth, we define a bidding language for
communicating consumer and provider preferences to the market as well as report
back the match of the market-based allocation process.}}

this dynamic and inter-organizational setting, scheduling and pricing become
key challenges. Market mechanisms show promise for enhancing resource allocation
and pricing in grids. Current mechanisms, however, are not adequately able to
handle large-scale settings with strategic users and providers who try to benefit
from manipulating the mechanism. In this paper, a market-based heuristic for
clearing large-scale grid settings is developed. The proposed heuristic and

prediction markets to the field of foresight. Prediction markets are a structured
approach

to collect and aggregate information from groups and have recently gained
attention in

forecasting. Prediction markets go beyond simple forecasting and can contribute
to

foresight by providing advantages in terms of continuous and real-time information

aggregation, motivation of participation and information revelation as well
as costefficiency

and scalability. We suggest four promising fields of application for prediction

markets to enhance foresight: (1) continuous forecasting and environmental
scanning, (2)

combining with deliberative approaches, (3) continuous idea generation and (4)
expert

identification. We conclude by considering prediction markets as a nascent and
promising

method for foresight and advocate for further research.}}

It seems to be pro-moted as heavily as the "Grid" was a few years ago, causing
broad discussions on the differ-ences between Grid and Cloud Computing. The
first contribution of this paper is thus a de-tailed discussion about the
different characteristics of Grid Computing and Cloud Computing. This technical
classification allows for a well-founded discussion of the business opportunities
of the Cloud Computing paradigm. To this end, this paper first presents a business
model ontology for Clouds. It subsequently reviews and classifies current Cloud
offerings in the light of this ontology. Finally, this paper discusses challenges
that have to be mastered in order to make the Cloud vision come true and points
to promising areas for future research.}}

abstract = {The fundamental paradigm shift from traditional value chains to
agile service value networks implies new economic and organizational challenges.
As coordination mechanisms, auctions have proven to perform quite well in
situations where intangible and heterogeneous goods are traded. Nevertheless
traditional approaches in the area of multiattribute combinatorial auctions
are not quite suitable to enable the trade of composite services. A flawless
service execution and therefore the requester's valuation highly depends on
the accurate sequence of the functional parts of the composition, meaning that
in contrary to service bundles, composite services only generate value through
a valid order of their components. 

We present an abstract model as a formalization of a service value network.
The model comprehends a graph-based mechanism design to allocate multiattribute
service offers within the network, to impose penalties for non-performance and
to determine prices for complex services. The mechanism and the bidding language
support various types of QoS attributes and their (semantic) aggregation. We
analytically show that this variant is incentive compati-ble with respect to
all dimensions of the service offer (quality and price). Furthermore we study
the mechanism theoretically as well as on a simulation basis in order to analyze
strategic behavior of service providers within service value networks.

a compact bid representation particularly for highly configurable goods and

Electronic markets and especially online auctions gain more
and more importance and a plethora of market mechanisms is emerging on the
Internet. The great variety of trading rules hinders agents easily switching
between different marketplaces and therefore fragments the overall market –
supply and demand might fail to meet due to agents’ inability to interact with
the same market mechanism. The problem can be overcome by a descriptive auction
language (DAL) allowing for the machine-readable specification of arbitrary
auction mechanisms. The implications are twofold: on the one hand a market
engineer can coherently describe a mechanism by means of the language and
automatically deploy it via an auction runtime environment and, on the other
hand, a (software) agent can automatically deduce valid and reasonable actions
from the description of a previously unknown auction mechanism.

allocation and computational tractability. Therefore, 2 pricing mechanisms are
investigated, the generalized Vickrey auction and pricing per column. }}

Over the last couple of years prediction markets as a community forecasting

schemes and feedback mechanisms to motivate participants to contribute to such
an information exchange. We design a prediction market for economic derivatives
that aggregates macro-economic information. We show that the level of
participation is mainly driven by a weekly newsletter which acts as a reminder.
In public goods projects participation feedback has been found to increase
participants' contributions. We find that the induced competitiveness of market
environments seem to superpose classical feedback mechanisms. We show that
forecast errors fall over the prediction horizon. The market generated forecasts
compare well to the Bloomberg-survey forecasts, the industry standard.
Additionally we can predict community forecast error by using an implicit market
measure.}}

booktitle = {Proceedings of the IEEE International Conference on Service Oriented
Computing & Applications (SOCA 2011)},
year = {2011},
address = {Irvine, CA, US},
abstract = {Increasing popularity of cloud-based services has led to the emergence
of cloud marketplaces where services from different providers are offered, usually
in the form of a catalog.

The customers' decision about buying offered services is based on idiosyncratic
preferences regarding non-functional service attributes, e.g., price, provider
reputation, and quality of service. Customer preferences are typically unknown
to providers at the time the service portfolio (i.e. quality and price choices)
is specified. Thus, from a microeconomic perspective, we have to deal with
information asymmetry in markets, which complicates the challenge of finding
the profit maximizing service portfolio.

This paper presents a generic economic framework based on customer self-selection
to address the above-mentioned optimization for a cloud service provider. The
contribution is two-fold: We characterize a multi-attributive customer preference
function for cloud services based on a continuum of potential customers. Thereby
each infinitesimal demand of a customer is characterized by a vector of minimum
quality values for each of the different attributes and a maximum willingness
to pay. The demand framework addresses the phenomenon of product cannibalization.

We then formulate the service providers' optimal service portfolio design. This
grants the provider maximal profit through optimal combination of potential
values of the chosen attributes.}}

contribute to an overall value proposition. SVNs provide means for the ad-hoc
composition of services that satisfies individual customers' needs. However,
the distributed nature of these environments and the opportunistic behavior
of participants require a purposeful design of incentives. Our contribution
is threefold: We (i) provide an auction mechanism  — the Complex Service Auction
-- to coordination value creation in SVNs which is incentive compatible in
dominant strategies (truthful). To restore budget balance -- the prerequisite
for a mechanism's sustainability -- and to implement incentives that increase
a network's degree of interoperability, we (ii) present the Interoperability
Transfer Function (ITF). Applying an agent-based simulation method, we (iii)
numerically show that this payment scheme limits strategic behavior of service
providers and strengthens interoperability endeavors compared to a benchmark
transfer function.}}

composite business services which results in a managerial overhead generated
from multiple contractual relations. The contribution of this paper is threefold:
(i) We analyze the fundamental requirements in the context of describing services,
quality and agreements as well as their aggregation in a generic manner. Based
on the results, we (ii) provide a holistic framework that enables the automation

of service provision and to incentivize providers. In a scenario, where an
intermediary coordinates complementary service providers and consumers, we derive
the following results: the intermediary should not pursue as high as possible
penalties because there are profit-maximizing providers’ effort and penalties
which decrease with the number of providers; a particular service provider’s
penalty should not depend on this provider’s but on all other service providers’
probabilities of service delivery; the intermediary should react to a cost
reduction of one service provider or to an increase of consumer’s valuation
by increasing all service providers’ penalties.}}

has shifted from providing static and predefined functionality to highly
configurable services that can be dynamically combined by customers. This new

to a high configuration complexity and presents new challenges in the field
of planning and pricing of service offerings such as validation of service
configurations as well as combinations, and price determination of service
mashups. Facing these challenges this paper presents an ontology for describing
technical as well as economic interdependencies between services and shows how
planing and pricing algorithms for dynamic Web scenarios can be implemented
based on this ontological knowledge. As proof of concept we present the
implementation of a Service Mashup Planner and show how this tool can be used

abstract = {Prediction markets are a promising approach for predicting uncertain
future events and developments. These markets will work well if they are efficient
and in efficient markets, one does not expect arbitrage opportunities to be
persistent. This paper therefore studies whether pure arbitrage opportunities
existed in a sports prediction market. Moreover, market liquidity can become
an issue in prediction markets since new information is potentially not
immediately reflected in trading prices and traders might also lose interest
in the markets if they are illiquid. This paper therefore analyzes whether traders
try to exploit illiquidity by taking on the role of market makers in prediction
markets.  

Our analysis of a sports prediction market for the FIFA World Cup 2006 shows
that prediction markets also appear to be efficient in the sense that there
are few substantial arbitrage opportunities available. Furthermore, we find
that market markers play an important role in prediction markets. They serve
as liquidity providers and allow for continuous trading.

our understanding of how auctions work on human behaviour is still rather limited.
In this paper we analyse the impact of emotional processes on the decision making

study, in which human agents take part in a Dutch auction experiment, while
their physiological parameters are recorded simultaneously. Parameters evaluated
in this study are the electrodermal activity and the heart rate of the experiment
participants. Based on the physiological results, we conclude that human agents
tend to cognitively set a price at which they want to end the auction, but once
they reach that specific price, they are tempted due to emotional processes
to wait a little longer in order to increase their nominal payoff. Further we
argue that the adaption of psychophysiological methodologies is not limited
to mechanism design, but can be of considerable assistance for successful design
of  nformation systems in general.}}

double auction mechanism for the allocation and pricing of energy resources

grids and their coupling to the large scale power grid. Furthermore we introduce
an emergency fail over procedure that keeps the micro energy grid stable even
in cases where the auction mechanism fails. As the underlying energy allocation
problem itself is NP-hard, we derive a fast heuristic for finding efficient
supply and demand allocations. In addition we show the applicability of this
approach through numerica.}}

is that no real money should be involved for billing the resources. In this

the requirements from the particle physics community this mechanism combines
the advantages of reputation and payment mechanism in one coherent system to

abstract = {One of the main contributions of classical mechanism design is the
derivation of the VCG mechanisms. The class of VCG mechanisms are the only
mechanisms that are strategy-proof and more importantly allocative efficient.
The well-known Generalized Vickrey Auction (GVA) is the corresponding auction
format of a VCG mechanism for the combinatorial allocation problem. From a
computational perspective the GVA has to solve two problems: (1) the
winner-determination (2) the determination of the prices. However, both problems
are complex (NP-hard). The Pricing Per Column (PPC) auction is another approach
to solve the combinatorial allocation problem. In essence, it applies the Vickrey
principle to any possible combination of goods and determines the overall winning
bids. PPC is computationally less demanding, however, it can be shown that PPC
is not necessarily efficient. Apparently, solving the tension between
computational and game-theoretic properties is a challenging task in mechanism
design. Engineering auctions suggests to lower requirements upon the auction.
In this paper the evaluation of the PPC concerning approximate efficiency is
presented - in an analytical and simulative evaluation the PPC is compared to
the GVA and it is shown that the efficiency losses incurred by the PPC mechanism
are very small.}}

that monetary incentives do not necessarily increase performance. In this paper,
we study the impact of monetary investments by comparing predictions from the
play money market STOCCER to those of the real money market BLUEVEX. Perhaps
surprisingly, the play money market STOCCER performs better than the real money
market BLUEVEX. However, we believe it is speculative to assume that play money
was the only reason for the good prediction derived from market prices in STOCCER.
We discuss several differences between the two sports forecasting exchanges

future experiments. }}

abstract = {In coordination theory, markets stand for flexibility and dynamics.
Today’s implementations of electronic marketplaces, however, limit the flexibility
in a sense that processes along the market transaction are rigid and the provided
functions proprietary. In order to further foster flexibility in market
coordination, we propose breaking down marketplaces into services. These services
can then be composed to customized market processes that trace proven
company-internal business processes, instead of prescribing a least common
denominator for all marketplace participants. This turns a marketplace operator
into a service-broker who provides merely the very fundamental infrastructure.
All other functions can be delivered by independent specialized providers and
flexibly assembled to processes. As such, the marketplace operator is not only
an intermediary in the traditional sense for bringing trading partners together
but also specialized service providers and their customers. Thereby, he guarantees
reliability and quality of service levels for the providers’ products. Our paper
presents a framework that enables the configuration and implementation of a
service-based electronic marketplace. Step by step high-level market processes
are decomposed into manageable and autonomously implementable components. As
a proof-of-concept we built a prototype using BPEL4WS and the Web Service
technology.}}

considerably. Spontaneity, however, imposes severe informational requirements
on the market participants. Informational requirements are twofold: Firstly,
participants have to agree on a common vocabulary for that spontaneous market.
Secondly, they need precise information about how the trading process is
organized. Due to the lack of a central market operator these common
understandings must be determined by the market participants themselves. Prior
to any market process, these terms and regulations must be distributed by the
market participant that initiates the market process. This raises the question
concerning the used ontology. Standards describing (business) processes are
available in general, but are currently not suitable for ephemeral markets.
Electronic markets are extremely context sensitive, making the establishment
of common understandings crucial as well as difficult. This paper uses structural
similarities of markets and creates a Minimal Market Model. Since this model
is for all conceivable markets constituent, it can be used as the core component.
As any market is founded on this minimal model, it can be systematically extended
to capture the peculiarities of each particular market. The derivation of the
Minimal Market Model is founded on a solid ground of economic theory and refined
such that it can be expressed in a formal way.}}

a genetic algorithm. The evolving strategies determine the bidding behaviour

system leads to a finite sequence of states. Hence, the sequence

of states is not fixed, and each state can be individually

parameterised. These characteristics enable an individual

processes and thus provides genericity in electronic negotiations.}}

was already predicted in the mid-90s but hitherto remains a bold vision. Although
software agents have the potential of fully automating processes, real world
agent-based applications are very limited in number. Even in the case of
electronic markets software agents are rarely employed, albeit they can act
as autonomous representatives of human negotiators.

The prototypical approach presented in this paper seizes the idea of an
agent-based electronic marketplace and describes multilateral negotiations as
a core of an electronic trading system. Owing to their open format (i.e. open
bidding), agent-based multilateral negotiations are expected to reduce transaction
costs and to improve the negotiation outcome. The multilateral negotiations
are presented in two different environments: in AMTRAS, an agent-based marketplace
for bonds, as well as in VTR, a web-based trading system for stocks. Two key
features of these negotiations are the revelation of all bids, and the anonymous
nature of trading. The information released in the negotiation constitutes the
basis for further research such that the agents are capable of deploying own
strategies inferred from the other’s bidding behavior. The paper concludes with
some recommendations as to how automation of the bidding process can be achieved
using software agents’ intelligence.

problems can be seen as orders that have to be fulfilled by a group of agents
having own intentions, i.e. to contribute to the problem solving process in
order to gain some profit. Several fundamental criteria are derived to evaluate
market like coordination mechanisms. The central criterion is the efficient
allocation of jobs to agents. Assuming a relationship between classes of
operational planning problems and certain coordination mechanisms, first of
all planning problems are classified on the basis of their relevant attributes.
Secondly, adequate coordination mechanisms for each of these classes are
introduced on the basis of auction theory. It turns out that all these mechanisms
share a common basis: the Vickrey auction}}

doing so, beside medical objectives also economic as well as technical goals

promising for healthcare institutions, since there is heterogeneous and wide
scattered information which is needed for successful care. The introduction
of an IT-based service enables to digitize and provide information in time.
But introducing IT-based services also rise to a challenge as healthcare services
are mainly produced by human service personnel with heterogeneous education
levels (physicians, paramedics, nurses, etc). Innovative IT-based services within
healthcare not only affect the business philosophy, but also aspects of
information transfer and feedback, acceptance of the IT-services and motivation
of the decision maker which uses the new services. Against this backdrop, our
goal is to develop a feedback mechanism in a case study, which supports the
decision making of the personnel within the stroke chain of survival in order
to improve motivation and provide learning affects. Our focus is the measurement

measurement is based on interviews and concrete consulting activities. Evaluating

More precisely, we highlight the fact that users must be supported with
personalized service recommendations if the full potential of the portal is
to be explored. The key challenge of next generation portal management is to
identify and promote each employee’s individually relevant service set by rating
implicit recommendations of similar users. In this respect, we suggest an
intelligent service called the “Ricommander” which is well suited to perform
this task.}}

is decreased. This eect is commonly explained by the fact that auction speed
has a direct eect on bidders' utility of suspense. We provide experimental
evidence that dierent clock speeds indeed have an impact on bidders' emotional
arousal, which in turn influences market behavior and outcome. To this extend
a bidder's skin conductance levels have been measured while participating in
Dutch auctions with varying clock speeds. The main nding of our physio-economic
study is that the degree of emotional arousal is signicantly higher in fast
Dutch auctions. Thereby we provide evidence for the missing link between the

and unpredictable environment which makes it impossible to cope with future
potentials, challenges, and risks by thinking of foresight as a purely technical
and analytical activity. Thus, recent literature has emphasized the need to
implement organizational foresight as a more human-centred and ongoing activity.
However, there is a lack of methods and instruments that would truly enable
socially-embedded and process-based foresight. In this paper, we discuss how
prediction markets may meet these requirements, especially in terms of continuity,
participation, and cost-efficiency. In particular, we identify three main fields
of application for prediction markets to enhance current organizational foresight:
(1) continuous monitoring and action triggering, (2) enhancing traditional
foresight instruments, and (3) idea generation and expert identification. Finally,
although prediction markets seem to be a promising approach for organizational
foresight, we address remaining research questions that have to be answered
before applying prediction markets on a large.}}

abstract = {The increasing interconnection between computers has created the
vision of a Computational Grid. Within this network, computer resources are
accessible to anyone participating in the Grid. This has major ramifications
since organizations that have computational demand are not required to purchase
and maintain computer resources for their own. Instead, it is possible that
computation can be performed spontaneously by other resources in the Grid that
are not under the control of the (temporary) user. The corresponding suppliers
of computation can be resource owners that have computer resources available
(e.g. computer center operators). However, one of the key problems in the
Computational Grid is to decide which jobs are to be allocated to which resources
at which time. In this context, the use of market mechanisms for scheduling
and allocating Computational Grid resources is a promising approach to solve
these problems. Currently, most of the market mechanisms that are available
for the Grid only insufficiently account for the peculiarities of Grid and are
thus widely inapplicable. This paper describes the design of a market-based
architecture for allocating and scheduling resources like processors or storage
space. Firstly, the economic properties which the proposed market mechanism
should satisfy are elicited. Secondly, comparable efforts

in designing mechanisms for Grids and related domains are discussed. Since none
of these mechanisms is directly applicable, an architecture for the Grid is
tailored. Finally, the proposed mechanism is evaluated according to its
computational properties.}}

impliziter Transaktionskosten}},
booktitle = {10th Symposium on Finance, Banking, and Insurance},
year = {2005},
abstract = {Der verst\"{a}rkte Wettbewerb zwischen Wertpapierb\"{o}rsen um die
Liquidit\"{a}t der Anleger hat in den letzten Jahren vielerlei Innovationen
im Bereich der Marktmodelle hervorgerufen. Traditionell be-zogen sich diese
Innovationen auf Aspekte der Publizit\"{a}t (offenes Orderbuch), der Einschaltung
von Intermedi\"{a}ren und der Preisfindung (XetraBest). In der letzten Zeit
wurden aber auch verst\"{a}rkt Innovationen im Bereich der Ordertypen (Iceberg
Order) vorgenommen.


Bereits 1971 schlug Fischer Black im Financial Analyst Journal eine weitere
Innovation – eine Order mit diskretion\"{a}rem Spielraum vor, die die Vorteile
von limitierten und unlimitierten Auftr\"{a}gen vereint: eine sofortige
Ausf\"{u}hrung, ohne daf\"{u}r die gesamte Geld-Brief-Spanne bezahlen zu
m\"{u}ssen. Ein solcher Ordertyp kann demnach im \"{u}bertragenen Sinne als
\"{u}berlegener Ersatz f\"{u}r unlimitierte Auf-tr\"{a}ge angesehen werden,
da Sofortigkeit zu besseren Konditionen angeboten wird.


So ist es wenig verwunderlich, dass einige B\"{o}rsen und ECNs (z.B. NASDAQ,
Instinet) bereits innova-tive Ordertypen, wie etwa die Pegged oder Discretionary
Order anbieten. Broker und Banken (z.B. Sino, InteractiveBrokers) simulieren
mit Hilfe ihrer Backend Systeme selbst anpassende Ordertypen. Allerdings sind
die Implikationen dieser Innovationen auf die Marktqualit\"{a}t nahezu unbekannt.
Als solches ist die aufgestellte Behauptung, dass diese Ordertypen der
unlimitierten Order \"{u}berlegen sind, kritisch zu hinterfragen.


Der vorliegende Beitrag nimmt die Idee einer sich selbst der Marktlage anpassenden
Order auf und untersucht einen innovativen Ordertyp – die Relativ Order –
hinsichtlich seiner Wirkung auf die Marktqualit\"{a}t. Die verwendete Order
orientiert sich dabei an der von Brown und Holden im Journal of Financial and
Quantitative Analysis vorgestellten Adjustable Order.


Anders als bei Brown und Holden wird der neue Ordertyp im vorliegenden Beitrag
mit Hilfe eines Simulationsmodells untersucht. Diese Analysemethode hat
gegen\"{u}ber einem analytischen Ansatz den Vorteil, dass nicht nur das
Gleichgewicht in einzelnen Handelszeitpunkten, sondern der gesamte Marktprozess
untersucht werden kann. Der Beitrag adressiert damit zwei zentrale
Forschungsfragen:
 

•	Erstens wird untersucht, inwiefern die Einf\"{u}hrung der Relativ Order die
Marktqualit\"{a}t beein-flusst.


•	Zweitens wird analysiert, inwiefern Simulationsmodelle einen Beitrag f\"{u}r
das Markt Design liefern k\"{o}nnen.


Die Simulation zur Beantwortung der ersten Forschungsfrage unterst\"{u}tzt die
Annahme, dass sich die Relativ Order im Spannungsfeld von Sofortigkeit und der
Bezahlung der Geld-Brief-Spanne positio-niert. Es zeigt sich, dass durch die
Nutzung der Relativ Order gegen\"{u}ber der Abgabe einer marktnah limitierten
Order die Ausf\"{u}hrungswahrscheinlichkeit des Auftrags deutlich erh\"{o}ht
werden kann und dadurch gleichzeitig dessen Ausf\"{u}hrungsdauer sinkt. Im
Gegenzug ist die erzielte Bieterrente etwas geringer als bei Nutzung einer
marktnah limitierten Order. ...}}

process between agents in a market aiming at an agreement for a mutual consent

Matchmaking includes the determination of the relevance of a specific offer

fit the request best; and (ii) to incrementally evaluate the relevance of modified
offers in negotiation rounds.

Multidimensional matchmaking describes offer and request structures which consist
of many attributes clustered along multiple dimensions. The business logic applied
in the matchmaking process is also structured along these dimensions. In this
work the matchmaking architecture \GRAPPA (Generic Request Architecture for
Passive Provider Agents) is presented and evaluated in the human resources domain.
The evaluation results are derived by comparing \GRAPPA matchmaking results
with the rankings of (i) a set of human experts; and (ii) a commercial search

abstract = {The energy sector will undergo fundamental changes

over the next ten years. Prices for fossil energy resources are

continuously increasing, there is an urgent need to reduce CO2

emissions, and the United States and European Union are strongly

motivated to become more independent from foreign energy imports.

These factors will lead to installation of large numbers of

distributed renewable energy generators, which are often

intermittent in nature. This trend conflicts with the current

power grid control infrastructure and strategies, where a few

centralized control centers manage a limited number of large power

plants such that their output meets the energy demands in real

time. As the proportion of distributed and intermittent generation

capacity increases, this task becomes much harder, especially as

the local and regional distribution grids where renewable energy

generators are usually installed are currently virtually

unmanaged, lack real time metering and are not built to cope with

power flow inversions (yet). All this is about to change, and so

the control strategies must be adapted accordingly. While the

hierarchical command-and-control approach served well in a world

with a few large scale generation facilities and many small

consumers, a more flexible, decentralized, and self-organizing

control infrastructure will have to be developed that can be

actively managed to balance both the large grid as a whole, as

well as the many lower voltage sub-grids. We propose a competitive

simulation test bed to stimulate research and development of

electronic agents that help manage these tasks. Participants in

the competition will develop intelligent agents that are

responsible to level energy supply from generators with energy

demand from consumers. The competition is designed to closely

model reality by bootstrapping the simulation environment with

real historic load, generation, and weather data. The simulation

environment will provide a low-risk platform that combines

simulated markets and real-world data to develop solutions that

can be applied to help building the self-organizing intelligent

energy grid of the future.}}

Zweitens stellt das ver\"{a}nderte regulatorische Umfeld erh\"{o}hte Anforderungen
an die datentechnische Vernetzung des Energiesystems. Durch die Entkopplung
von Stromerzeugung, -\"{u}bertragung und -verteilung m\"{u}ssen

unterschiedliche Akteure entlang der Wertsch\"{o}pfungskette \"{u}ber gemeinsame
Schnittstellen miteinander kommunizieren und interagieren. Neue Vorschriften
zur Standardisierung, zum Messwesen und zur Verbrauchstransparenz erzeugen zudem
gro\sse Datenmengen, die in intelligenten automatisierten Prozessen verarbeitet
werden m\"{u}ssen.



Als dritter Faktor schlie\sslich bewirken technische Entwicklungen und steigende
Energiepreise, dass in Zukunft vermehrt Strom aus erneuerbaren Energiequellen
sowohl auf Basis einer verst\"{a}rkt dezentralen als auch aus einer weiterhin
vorhandenen zentralen Versorgungsstruktur in das Stromnetz integriert werden
m\"{u}ssen. Dies erfordert ein wesentlich h\"{o}heres Ma\ss an Flexibilit\"{a}t
im Bereich der Spannungshaltung und der effizienten Lastflusssteuerung als im
derzeitigen System vorgesehen ist.



Diese drei treibenden Faktoren wirken zu einer Zeit, in der ein erheblicher
Investitionsbedarf in das deutsche und europ\"{a}ische Stromversorgungssystem
besteht. Nahezu die H\"{a}lfte der installierten Kraftwerkskapazit\"{a}t in
Deutschland muss in den kommenden Jahren ersetzt oder modernisiert werden, der
massive Ausbau der Stromnetze wird im gleichen Zeitraum ebenfalls erfolgen
m\"{u}ssen. Parallel wird

ein erheblicher Teil der privaten Haushalte renovierungsbed\"{u}rftig. Aufgrund
steigender Energiepreise werden bei den hier anstehenden Instandsetzungsarbeiten
zunehmend neue Energiespartechnologien und kommunikative Endger\"{a}te eingesetzt.



Angesichts dieses Investitionspotenzials besteht die einmalige Chance, einen
\"{U}bergang des derzeitigen Energiesystems hin zu einem Internet der Energie
zu f\"{o}rdern, in dem durch die intelligente Koordination zwischen Erzeugung
und Verbrauch h\"{o}chstm\"{o}gliche Effizienzgewinne bei der Nutzung knapper
Energieressourcen erreicht werden k\"{o}nnen. Die notwendigen Technologien f\"{u}r
die intelligente und effiziente Erneuerung des Energiesystems sind heute
weitestgehend vorhanden. Die Kombination und Integration der verf\"{u}gbaren
Systeme ist jedoch noch weit hinter den M\"{o}glichkeiten zur\"{u}ckgeblieben.
Es bedarf demnach vor allem einer Weichenstellung bei den beteiligten Industrien
und der Politik, die sich auf Handlungsma\ssnahmen und auch auf technische
Standards einigen m\"{u}ssen, um den anstehenden Ver\"{a}nderungsprozess aktiv
und zielgerichtet zu gestalten.



Der Informations- und Kommunikationstechnologie kommt bei der Entwicklung einer
zukunftsf\"{a}higen Energieversorgung eine Schl\"{u}sselrolle zu. Sie ist die
Basis f\"{u}r die Realisierung eines zuk\"{u}nftigen Internets der Energie,
das hei\sst der intelligenten elektronischen Vernetzung aller Komponenten des
Energiesystems. Durch diese verst\"{a}rkte Vernetzung k\"{o}nnen
Erzeugungsanlagen, Netzkomponenten, Verbrauchsger\"{a}te und Nutzer des
Energiesystems untereinander Informationen austauschen und selbstst\"{a}ndig
ihre Prozesse aufeinander abstimmen und optimieren. So entwickelt sich das
bisherige Energienetz mit passiven, informationsarmen Komponenten und einer
\"{u}berwiegenden Einweg-Kommunikation hin zu einem marktorientierten,
dienstebasierten und dezentral organisierten System, in dem interaktive
Optimierungsm\"{o}glichkeiten

und neue Energiedienstleistungen geschaffen werden k\"{o}nnen. Durch einen
verst\"{a}rkten Einsatz von energetisch optimierender Hausautomation und von
Smart Metering haben Privatkunden, \"{o}ffentliche Einrichtungen und auch kleine
und mittlere Unternehmen die M\"{o}glichkeit, ihren Energieverbrauch zu reduzieren
oder zeitlich so zu verschieben, dass Lastspitzen und Engpasssituationen vermieden
werden. Verbesserte Energiemanagementsysteme auf der \"{U}bertragungs- und
Verteilnetzebene erm\"{o}glichen, dass dezentrale Erzeugung und erneuerbare
Energiequellen im gro\ssen Ma\ssstab optimal eingesetzt werden k\"{o}nnen, ohne
dabei die

Systemstabilit\"{a}t und -qualit\"{a}t zu beeintr\"{a}chtigen. Die gr\"{o}\sste
Herausforderung besteht indes darin, eine Integrationsebene zwischen
betriebswirtschaftlichen Anwendungen und dem physikalischen Netz zu schaffen,
welche eine Kommunikation komplexer, \"{u}ber heterogene Netze und Firmengrenzen
hinweg verteilter IT-Komponenten erm\"{o}glicht.



Der \"{U}bergang des derzeitigen Energiesystems hin zu einem Internet der Energie
l\"{a}sst eine Vielzahl m\"{o}glicher neuer Gesch\"{a}ftsmodelle entstehen.
Stromnetzbetreiber k\"{o}nnen sich zuk\"{u}nftig vermehrt zu
Informationsdienstleistern entwickeln; neue Dienstleistungen, wie beispielsweise
das Energiemanagement beim Kunden, werden entstehen. Neue Akteure werden in
den Markt eintreten, zum Beispiel Betreiber von virtuellen
Regelenergiekraftwerken. Durch eine an das Energieangebot angepasste Einbindung
von (hybriden) Elektroautos bietet sich zuk\"{u}nftig auch f\"{u}r den
Transportsektor eine neue M\"{o}glichkeit, aktiv an der Optimierung der
Energienetze mitzuwirken.



Als konkrete Handlungsempfehlungen zur Erschlie\ssung dieser neuen
Gesch\"{a}ftsfelder und zur Verwirklichung eines zukunftsf\"{a}higen intelligenten
Energiesystems werden im Rahmen dieses Papiers Ma\ssnahmen auf mehreren Ebenen
vorgeschlagen. Auf der technischen Ebene muss ein starker Fokus auf der
Koordination der Standardisierung in der Informations-, Kommunikations- und
Energietechnik liegen, die insbesondere eine durchg\"{a}ngige bidirektionale
Kommunikation zwischen Stromerzeugung und Endverbrauchern unterst\"{u}tzt. Neben
der F\"{o}rderung der Grundlagenforschung und Ausbildung in den relevanten
technik- und wirtschaftswissenschaftlichen Disziplinen ist insbesondere auch
die F\"{o}rderung von Initiativen zur angewandten Forschung und zur Pilotierung
des Internets der Energie erforderlich, um Konzepte zu erproben und Erkenntnisse
aus der Forschung in den laufenden Transformationsprozess der Energiewirtschaft
einzubringen. Um sicherzustellen, dass die innovativen Konzepte einer
intelligenten und effizienten Energieversorgung auch tats\"{a}chlich zum Einsatz
kommen, m\"{u}ssen nachhaltige Innovationsanreize insbesondere f\"{u}r
Netzbetreiber geschaffen werden. In diesem Bereich muss die Regulierung
entsprechend gestalterisch eingreifen. Schlie\sslich ist eine geeignete
\"{O}ffentlichkeitsarbeit erforderlich, um alle relevanten Akteure dar\"{u}ber
zu informieren, wie sie zur Umsetzung der Vision des Internets der Energie
beitragen k\"{o}nnen.



Die identifizierten Handlungsempfehlungen k\"{o}nnen wesentlich dazu beitragen,
das heutige Energiesystem zu einer noch effizienteren, zukunftsf\"{a}higen
Energieversorgungsinfrastruktur zu entwickeln und damit die

internationale Spitzenposition deutscher Unternehmen und Forschungseinrichtungen
im Bereich intelligenter und integrierter Energietechnologien zu st\"{a}rken
und auszubauen.}}

abstract = {To navigate turbulent business environments, organizations have
to develop foresight capacities that enable them to anticipate probable futures,
respond rapidly to emerging changes, and support future oriented action. However,
there are remaining barriers that impede a wider implementation of foresight.
In particular, the necessities to deal with the future, anticipate change, enhance
participation, and reduce costs and complexity call for new methods to improve
current foresight activities. In this paper, we introduce prediction markets
to the field of foresight. We consider prediction markets can overcome some
of these barriers. Prediction markets are a structured approach to collect and
aggregate information from groups and have recently received a boost in popularity
in the area of forecasting. Yet, prediction markets go beyond simple forecasting
and can contribute to foresight by providing advantages in terms of continuous
and real-time information aggregation, motivation of participation and information
revelation as well as cost-efficiency and scalability. We suggest four promising
fields of application for prediction markets to enhance foresight: (1) continuous
forecasting and environmental scanning, (2) combining with deliberative
approaches, (3) continuous idea generation, and (4) expert identification. We
conclude by considering prediction markets as a nascent and highly promising
toolkit for foresight and advocate for further research.}}

abstract = {Economists are increasingly being called on to give advice about
how to design markets” (Varian 2002). Accordingly market designers have to apply
principles of economic analysis to design markets for the private sector (e.g.,
Ebay) as well as in highly sophisticated domains like financial trading platforms
(e.g. Nasdaq, Xetra). Recently, the demand for market-like coordination in
decentralized systems has increased - in deregulated industries (e.g. FCC spectrum
auctions) as well as in supply networks or in the world of Web or Grid Services.
The basic coordination principles are the same for almost all of these scenarios.
In both areas (private or corporate), even small design mistakes decide over
the success or failure of an electronic marketplace. These mistakes do not only
concern the microstructure but just as well the ICT and the business structure.
Hence, Market Engineering focuses on the “structured, systematic and theoretically
founded procedure of analyzing, designing, introducing and also quality assuring
and advancing electronic market platforms as well as their legal framework -
regarding their microstructure, ICT infrastructure, and business structure
simultaneously”(Weinhardt, Holtmann, Neumann 2003), to guide market engineers
in their task and to support them with a preferably integrated tool set. After
introducing the Market Engineering as a comprehensive approach the talk will
focus on two different perspectives to Web and Grid services: the first is market
engineering as a generic methodology for building Web Service based market like
co-ordination systems for various areas including Grid computing; the second
is related to market engineering as a useful mechanism for an efficient
coordination through “trading” Web or Grid Services.

What has been neglected so far is its striking relevance for electronic services.
Whereas consumers’ expectations about information goods are often vague and
transient, their requirements are pronounced and specific when it comes to the
functional and non-functional characteristics of electronic services. Moreover,
modular services can be combined and configured into service mashups that meet
virtually every conceivable consumer requirement. In this vein, the long tail
phenomenon can be leveraged into a new dimension -- the long valley, where every
service exerts positive network externalities on the remaining services, thereby
spurring an increase in supply and demand. The combinatorics of constructible
service mashups are enabled by universally accessible service orchestration
platforms known as Service Value Networks (SVNs). This article shall not only
pave the way for a rising research area on a new business trend, but will also
help business actors to harness the opportunities opened up by SVNs.}}
