Modeling and managing business processes that span multiple organizations involves new challenges, mainly regarding the ability to cope with change, decentralization, and the required support for interoperability. In this paper, we present an approach to modeling cross-enterprise business processes based on the model-driven architecture (MDA). Starting from the ATHENA interoperability architecture, we propose a conceptual architecture for cross-enterprise business processes. Then, we present a methodical approach towards designing cross-enterprise business processes based on a model-driven architecture. The core contribution of the paper is a set of original mappings at and across different layers of the model-driven architecture, including a mapping from ARIS to UML and the Business Process Definition Metamodel (BPDM). © Springer-Verlag 2004.

software agents that play a role in E-commerce and E-government applications involving the Internet often contain information about the identity of their human user such as credit cards and bank accounts. This paper discusses whether this is necessary: whether human users and software agents are allowed to be anonymous under the relevant legal regimes and whether an adequate interaction and balance between law and anonymity can be realised from both the perspective of Computer systems and the perspective of Law.

Law-abiding and integrity on the Internet: A case for agents

引用

Artificial Intelligence and Law 2004年第1期12卷 5-37页

software agents extend the current, information-based Internet to include autonomous mobile processing. In most countries such processes, i.e., software agents are, however, without an explicit legal status. Many of the legal implications of their actions (e.g., gathering information, negotiating terms, performing transactions) are not well understood. One important characteristic of mobile software agents is that they roam the Internet: they often run on agent platforms of others. There often is no pre-existing relation between the “owner” of a running agent’s process and the owner of the agent platform on which an agent process runs. When conflicts arise, the position of the agent platform administrator is not clear: is he or she allowed to slow down the process or possibly remove it from the system? Can the interests of the user of the agent be protected? This article explores legal and technical perspectives in protecting the integrity and availability of software agents and agent platforms.

IEEE International Conference on Fuzzy systems (FUZZ-IEEE)

This paper gives contribution to the construction of an image mosaic by pasting together a sequence of photographs taken by a regular digital camera from the same position but in different directions. In order to find the best match between two overlapping images, a fuzzy-genetic based algorithm is presented. A translation vector with a minimal difference between the common picture parts has to be found. The difference is defined using the fuzzyfied contours of each images. The search of the optimal translation is considered as a minimization process. This paper proposes a method that uses genetic algorithms to find the minimum point corresponding to the optimal translation. Using the fuzzy based comparison of the two images yields a fast fitness function, while the implementation of the proposed method in a genetic hardware has a low and variable computational cost. The precision of the method is inverse-proportional with the computational time, which makes it ideal to be used in real time systems.

This paper surveys and investigates the strengths and weaknesses of a number of recent approaches to advanced workflow modelling. Rather than inventing just another workflow language, we briefly describe recent workflow languages, and we analyse them with respect to their support for advanced workflow topics. Object Coordination Nets, Workflow Graphs, WorkFlow Nets, and an approach based on Workflow Evolution are described as dedicated workflow modelling approaches. In addition, the Unified Modelling Language as the de facto standard in object-oriented modelling is also investigated. These approaches are discussed with respect to coverage of workflow perspectives and support for flexibility and analysis issues in workflow management, which are today seen as two major areas for advanced workflow support. Given the different goals and backgrounds of the approaches mentioned, it is not surprising that each approach has its specific strengths and weaknesses. We clearly identify these strengths and weaknesses, and we conclude with ideas for combining their best features. © 2003, IOS Press. All rights reserved.

IEEE International Symposim on High Assurance systems Engineering

作者： E. Nett M. Gergeleit M. Mock Distributed Systems Institute IVS Otto von Guericke Universität Magdeburg Germany Institute for Autonomous intelligent Systems GMD-German National Research Center of Information Technology Germany

The final objective of the described project is to develop and implement techniques for a reliable cooperation of autonomous mobile systems that can be used for future traffic management systems. The approach relies on the ability of the systems to communicate among themselves in order to make efficient use of available shared resources (e.g. road space). In the context of automotives this means that computer-based driving assistants not only support humans in handling their own vehicles but also in interacting with the individual vehicles in the neighborhood The vision is an embedded, distributed traffic control system that is provided by the cooperation of the participating units, and thus is more robust and scalable than centralized approaches. Besides the 'obvious' requirements on high assurance computing in traffic control systems, the design and implementation of such systems require the ability of coordination while obeying the necessary real-time and safety constraints. This paper motivates the approach, presents an envisaged system architecture and sketches the design of the basic communication layers of this architecture that can fulfill the realtime and safety requirements. Finally, it introduces a lab-scale evaluation and demonstration scenario that proves the feasibility of the concepts.

International Symposium on Object-Oriented Real-Time distributed Computing

作者： M. Mock M. Gergeleit E. Nett Distributed Systems Institute Otto-von-Guericke-Universitaet Magdeburg Germany GMD German National Research Center for Information Technology Institute for Autonomous Intelligent Systems

Object-oriented frameworks have become a key element in the design of distribution systems. They make the existence of the physical and operating system level resources transparent to the designer and provide the abstract view of the distributed systems as a set of objects that interact by invoking well-defined interfaces of each other. Easy reuse of existing components, location transparency and implementation hiding are the main ingredients of such frameworks that simplify the task of designing distributed systems drastically. It is desirable to take advantage of these benefits when designing distributed real-time systems, too. However, this goal conflicts with the essential need to consider the allocation of system resources when real-time requirements must be met. Here, system level resource issues such as execution times on CPUs, thread switches, occurrence of interrupts, and message delays are of primary interest. Our approach to solve this dilemma is to allow and support the designer of distributed real-time object-oriented applications to become aware of system level resources. We present a monitoring tool JewelDC that allows monitoring of distribution activities (i.e. nested sequences of object invocations) in a distributed object-oriented framework. distributed activities are visualized at the abstract object level while simultaneously revealing their use of system level resources. The tool has been implemented for DCOM on Microsoft Windows NT 4.0.

Workshop on Object-Oriented Real-Time Dependable systems (WORDS)

作者： M. Mock E. Nett Institute for Autonomous intelligent Systems German National Research Center for Information Technology (GMD) Saint Augustine Germany Distributed Systems Institute University of Magdeburg Magdeburg Germany

There is a general trend in designing distributed control systems to give an increasing amount of autonomy to the individual nodes of such systems. Two interrelated system layers must be considered when autonomous systems have to be coordinated under real-time constraints: the distributed programming paradigm and the communication layer. We analyze current trends and options, and give an approach for an integrated architecture.
