To meet the challenge of educating a new generation of managers and software engineers, namely e-business engineers, a generic pedagogical scenario and technical support is proposed as case-teaching driven, model-based, role-play simulation games. Three core areas are identified then in needs of technical support. We elaborate briefly the design rationale and the status of its implementation using intelligent agent technology, with the beer distribution game as an illustration.

High dynamic computing environment makes quality of service (QoS) guarantee more important to distributed system. It should possess self-tuning capability reacting to external environment variation such as fluctuating workload. This paper proposed an adaptive self- configuration framework for EJB platform, which can automatically tune configuration parameters to preserve QoS when workload changed. The key point of this framework is a performance model based on layered queuing network, which guides the search for the best combination of configuration parameters to satisfy performance requirement of EJB application. We have prototyped this self-configuration framework on an EJB server named OnceAS, and the experiment results showed that through the framework's control, system performs well on QoS goal.

Computational group concepts (e.g. total = quantity times unit price) in business document exchange are very important concepts. However, semantic consistency issue exists in document exchange such that how the computational relationship in a computational group concept can be represented, conceptualized, reified and interpreted between heterogeneous business document contexts. This paper has discussed this issue and proposed a public operation concept strategy as the solution to representing, designing and implementing the computational group concepts.

The integration of software applications constitutes a challenging task. In particular, this applies to an a-posteriori integration approach where existing legacy systems - possibly supplied by different vendors - are coupled. Responding to this challenge, the service-oriented paradigm defines an architectural style for the construction of a heterogeneous application landscape. By abstracting services, applications are made available at a clean level suitable for integration. In this paper a model-driven approach for service development is presented which yields a modeling formalism - realized as a programmed graph rewriting system - to specify service descriptions and service compositions and facilitates generation of executable program code. Moreover, the "approach" is not only confined to the conceptual level. Rather, the approach is realized by a collection of support tools and a respective tool infrastructure.

Nowadays, there are a number of similar Web services over the Internet or intranet. They provide consumers with more choices according to their personalized QoS requirements. However, in current web service discovery and subscription, it takes consumers too much time on manual selection and cannot easily benefit from the wide QoS spectrum brought by the proliferating services. In this paper, we propose a QoS-aware discovery and subscription approach to free consumers from time-consuming human computer interactions as well as help them negotiate QoS with multiple service providers. The core idea of this approach is to build up a "virtual service" grouping function similar services together (called service pool) and dispatching consumer requests to the proper service in terms of QoS requirements. This paper makes contributions for the aggregation and usage of similar web services in a "consumer-centric" manner. Such manner is on-demand, user-friendly and efficient. On-demand means the aggregate is driven by consumers instead of providers. User-friendly means consumers do not select services, handle different WSDL of similar services and switch between services at runtime any longer. Efficient means it integrates an efficient service search engine, reduces the incorrect services by some filter, discover the aggregate by a polynomial complex algorithm.

The needs of the Service Economy have not been yet investigated in depth in academic research. This paper analyzes customer participation in services and considers the value-adding opportunities it offers. It proposes a conceptual framework for customer participation in services that is based on customer needs, the service offering and its outcomes. As experiences may be a major type of outcomes of the service process for the customer, we examine value-adding opportunities in dealing with customer experiences and we propose a service model for the association of needs, services and experiences. Such a model can be used for the development of customer-centric services, in which the customer is empowered to configure services according to his/ her needs and preferences, services which bring superior experiences and satisfaction. Based on the example of the tourism, which is experience-intensive, we describe the functional and technical aspects of the model.

E-Business and Strategic Management methodologies problems can be efficiently solved by using corresponding adaptive algorithmic procedures. A class of case studies representing a variety of characteristic E- Business problems is presented by considering the proposed algorithmic approach. The adaptability and compactness of the proposed algorithmic schemes combined by the proper choice of singular perturbation parameters allow the (near) optimum solution of a wide class of E-Business and strategic management problems.

Components within service-oriented systems require a mechanism to get in touch with offered services. A traditional approach from the field of Web services is a discovery agency provided by the infrastructure, where service providers register and service requestors submit their queries. In the field of dynamic adaptive systems we deal with systems which change their behavior according to the needs of their users during runtime based on context information. Therefore, the wiring of service providers and service requestors - known as the system configuration - may change often. As a consequence of the dynamics it is reasonable not to let the service requestor take care about the service discovery. Instead we propose a component model enabling the proactive configuration of service-oriented systems which will be described in this paper.

The level of autonomy and the efficiency of e- Marketplaces can be improved if automated negotiation support is available. Some parametric learning negotiation models have been proposed recently. These models allow a negotiator to learn the opponents' preferences based on previous offer exchanges. Nevertheless, these models make strong assumptions about the particular negotiation mechanism employed by the respective negotiation agent. This paper illustrates the design, development, and evaluation of a non-parametric negotiation knowledge discovery method which is underpinned by the well-known Bayesian learning paradigm. This method can discovery vital information about a negotiator's preferences without making any assumption about the underlying negotiation mechanism employed by the negotiator. According to our empirical testing, the proposed negotiation knowledge discovery method can speed up the negotiation process while maintaining the negotiation effectiveness. Our research work opens the door to the development of intelligent negotiation mechanisms to enhance modern e-Marketplaces.

In both e-commerce (EC) and service-oriented computing (SOC) environments, sellers or service providers interact with customers or service clients for services or transactions. From the point view of customers or service clients, the trust status of the seller or service provider is a critical issue to consider, particularly when the seller or service provider is unknown to them. Typically, the trust evaluation is based on the feedback on the service quality provided by customers and clients. Traditionally, the trust evaluation method is based on formulas only. This might be rigid to some complex applications, like SOC. In this paper, we propose a novel integrated trust management framework that is event-driven and rule-based. In this framework, the trust computation is based on formulas. But rules are defined to determine which formula and arguments to use according to the event occurred during the transaction or service. In addition, we also propose some trust evaluation metrics and a formula. A set of empirical studies has been conducted to study the properties of the proposed formula and how to control the trust change trend in both trust increment and decrement cases. The proposed framework is more generic and suitable for different domains and complex trust evaluation systems.
