    Virtual enterprises or organisations (VO) have been the focus of research for over a decade. Although proprietary implementations of VO management tools exist, secure tools based on interoperating open standards are not yet available. The open standards on which to build them are just being released as reliable implementations. The requirements of VOs for trust and security are presented, which lead to an architecture for a secure VO management framework. The design of such a framework is analysed to show how the current open Web service specifications could be used to implement it in practice. The need for the reliable and interoperable implementation of these essential Web services specifications is advocated. View full abstract»

    When Web services are composed, transactions are needed to maintain the consistency of the distributed data in all but the most trivial cases. Today's Web service transaction specifications still leave some issues unresolved, e.g., the specification of quality of service aspects. Therefore, we propose a modeling methodology that forces the software architect to address such issues at an early stage of development. The methodology is divided into four layers of UML diagrams which reference each other: structure, transactions, security, and workflow. This separation of concerns can also be used to incorporate the knowledge of several experts into the design. View full abstract»

    Web service protocol standards should be unambiguous and provide a complete description of the allowed behavior of the protocols' participants. Implementation of such protocols is an error-prone process, firstly because of the lack of precision and completeness of the standards, and secondly because of erroneous transformation of semantics from the specification to the final implementation. Applying the TLA+ paradigm we first consider the protocol on an abstract level. Safety properties taken from real world scenarios are compared to the facilities of the protocol. As result, we identified some limitation of applicability of the WS-BA protocol to abstract application use cases, modelled from the real world scenarios. These limitations are an omission of possible activities seen in the real world. Further WS-C and WS-BA make assumptions about the internal structures of the participants, violating SOA paradigm. The former error could be detected by the use of formal methods. The latter can be circumvented by a sophisticated implementation strategy. The proposed strategy of implementing WS-Coordination and WS-BusinessActivity allows non-intrusive integration of the transactional framework, considering SOA requirements. This paper describes the results of analysis and some design decisions taken during the proof-of-concept implementation of WS-C and WS-BA frameworks. View full abstract»

    The concept of MDA (model driven architecture) aims at the goal of longevity (through business logic and architecture migration between different platforms) and quality improvement (through raising the level of abstraction). In the context of business process modeling and execution a frictionless mapping between high level, platform independent business process definition and platform specific, executable code has to be achieved. In this paper we compare two existing real world mapping scenarios of IBM and Microsoft concerning Web service orchestration. One "top-down" approach starting with high-level UML models down to executable code, the other as a "bottom-up" approach, with proprietary modeling integrated within the IDE. We try to answer the question how far both proposals implemented the MDA concept yet and discuss how they could support our current project of a service oriented architecture for the manufacturing shop floor domain.

    In this paper we present a case example of how heterogeneous services and technologies can be integrated. We show a service-oriented architecture based on Web services to perform specific operations, issued by distributed processes through different protocols (HTTP, POPS, RMI and SMS), on a particular ERP system, namely the SAP R/3 system. The architecture results from the integration of two different service-oriented technologies: Java message service and SAP Java connector, and uses business process execution language for Web services choreography. We describe a prototype of the proposed architecture and discuss how a sample business operation, consisting of a purchase order input to SAP R/3 from any of a variety of technological devices, can be performed.

    Business process modeling (BPM) is one of the key factors in defining service-oriented solutions for business collaborations. Like in traditional software engineering there is a need for adaptable methodologies to develop information and communication technology (ICT) systems supporting collaborative business processes. In this work we introduce a categorization for the classification of modeling languages and approaches used to model collaborative business processes. Considering an example, we show how the classification of modeling languages and approaches facilitates the development of methodologies for collaborative business processes. View full abstract»

    Business rules define or constrain some business. Many different business rules engines exist to capture and manage the rules that comprise ones business. The lack of standards in the business rule area leads to different engine implementations and various rule representation formats. Furthermore, accessing rule-based knowledge in a uniform way from different heterogeneous applications in an enterprise computing environment poses many integration challenges. In this paper, we propose the design and implementation of a service-oriented approach on how to integrate different heterogeneous business rule engines by using our business rules broker architecture. Furthermore, we present a method to automatically expose the rule-based business knowledge as Web services by generating the Web service code at design-time. View full abstract»

    This paper describes an algorithm optimizing the discovery process for composed semantic Web services. The algorithm can be used to improve discovery of appropriate component services at invocation time. It performs semantic matchmaking of goals of a composed service to appropriate component services at publishing time. The semantic discovery problem at invocation time is therefore reduced to a selection problem from a list of available (already discovered) component services matching a goal of the composed service.

    Web services are software artifacts that can be accessed over the Internet. They can be seen as pay-per-view functionalities that are exposed by some service providers. If there are multiple providers for a Web service, then both the quality and price of the service become key factors when determining which provider to choose. We consider the problem of service allocation for multiple correlated Web services that can be serviced by potentially different Web service providers. We model this problem in a game-theoretic setting and design a reverse auction where optimal service allocation for the service requester is guaranteed. We also present an optimal strategy for the service provider when choosing its quality of service. View full abstract»

    Collaborative product commerce (CPC) is established to support the collaboration among the product design, product manufacturing, sales, marketing, services and so on. It is a one-off, dynamic process in order to respond the requirements of market. How to make a good notation about the requirements of CPC and collaboration relationships among the collaborators is becoming an important issue. It is a very important phase in the whole collaborative product commerce process, named as early requirements. This paper uses a goal and agent oriented approach (i* framework) to analyze and model early requirements of CPC. The collaborators in CPC are treated as strategic actors or agents and collaboration among them are depicted as dependency relationships. The model can be translated into formal language and suitable for automatic analysis that is used to verify early requirements and facilitate formal analysis in later phases. An example of an instance of CPC is used to illustrate. View full abstract»

    In this paper, we present a system for traceability in the food supply chain. The system is able to systematically store information about products and processes operating on products throughout the entire supply chain from farm suppliers to retailers. The system manages quality information too. Thanks to the use of the electronic business using extensible markup language (ebXML) standard, the traceability system also provides data homogeneity, scalability and interoperability.

    Electronic contracts play a key role in the automation of information technology (IT) processes by establishing a common context and a formal set of mutual agreements and expectations between the various parties involved in today's enterprise applications. We describe a novel approach for applying different types of electronic contracts to a complex IT management scenario with a specific focus on change management. Our implementation of a change management system and its quantitative evaluation shows that the use of electronic contracts helps in breaking down a complex change management problem into tractable parts and improves the quality of the accomplished solution.

    Today organizations face increasingly dynamic and competitive environments. Business agility aims to address these challenges. In this contribution, we aim to increase understanding about business agility by introducing a novel conceptualization. In addition, we aim to identify key research challenges that need to be addressed by future research. In order to achieve these goats, we first introduce different levels of analysis that explain how business agility integrates into existing organizational structures. Subsequently we define business agility to 1) be goal-oriented and 2) to represent a triadic problem consisting of the three dimensions time, control and information systems. Then we introduce an integrative concept of business agility that ties together the three dimensions and introduces parameters that enable an assessment of different degrees of business agility. Based on that, we identify two main research directions, organic information systems and decision support systems, which are of special relevance and importance in the quest for increasing business agility of organizations.

    In this paper we have developed a research model that illustrates the role of IT and knowledge management in building an agile operation. Acknowledging that there is more than one dimension to business agility, we focus on operational agility as a catalyst to enforce quality, cost effectiveness, and delivery, thereby meeting organizational objectives. To develop our model of agility, we build on existing theoretical constructs and identify absorptive capacity and dynamic capabilities as enablers of operational agility. Further, we recognize major IT knowledge management capabilities that are instrumental in building absorptive capacity and thus enhancing dynamic capabilities. We will utilize surveys of key decision makers to validate our model and have provided a rough outline of the type of questions that we will employ. View full abstract»

    Total cost of ownership (TCO) is of interest to business and academic communities because it expands the understanding of the real cost of technology beyond purchase cost. The dominant Gartner Group model describes 'hard' and 'soft' costs, including acquisition, control and operational costs. Such metrics though tend to focus on conventional, abstract categories of cost defined by accounting and management literatures, rather than cost as it is understood in the thick of the everyday work of actual organizational members. Our research attempts to address this, examining one particular group of costs, break-fix, in terms of how costs arise and are reasoned about in actual working practice. This paper describes these costs and relates them to wider issues of TCO. We highlight the barriers that exist to the implementation of a successful break-fix strategy and suggest technologies that facilitate such a strategy. View full abstract»

    In this paper we introduce a new interpretation of business and IT agility - a calculus of business change and the resultant IT change. We argue that business agility, the ability to respond with "smooth and dexterous performance", derives from a coordination structure for the business with strong implications for day to day operations. We relate the argument to an operational modeling approach that we have developed as well as with other contemporary concepts on complexity in business. Our modeling approach is distinguished by the concept of "business artifacts" and artifact-centered thinking. We have had considerable success with operational business modeling and we will draw on some examples to illustrate our arguments. View full abstract»

    Agility in IT services or business is closely linked with the ability to quickly compose new offerings to match specific and varying demands. A modular architecture is a key enabler for this ability. In this paper we provide a brief introduction how the principle of modularity may be applied to business services. We then present a proposal how modular business services can be modeled using SeeMe, a socio-technical modeling language. The ability to compose and adapt services to new demands depends critically on the coupling of the modules. We show how SeeMe models of module interfaces can be used to assess coupling between modules. In the outlook to further research we propose that the concepts of vague modeling as well as person, activity, and resource hiding may be used to assess the agility of business services.
