CrossFlow: Cross-Organizational Workflow Management for Service Outsourcing in Dynamic Virtual Enterprises

In this report, we present the approach to cross-organizational workflow management of the CrossFlow project. CrossFlow is a European research project aiming at the support of cross-organizational workflows in dynamic virtual enterprises. The cooperation in these virtual enterprises is based on dynamic service outsourcing specified in electronic contracts. Service enactment is performed by dynamically linking the workflow management infrastructures of the involved organizations. Extended service enactment support is provided in the form of cross-organizational transaction management and process control, advanced quality of service monitoring, and support for high-level flexibility in service enactment. CrossFlow technology is realized on top of a commercial workflow management platform and applied in two real-world scenarios in the contexts of a logistics and an insurance company

Foundations of B2B electronic contracting

Nowadays, flexible electronic cooperation paradigms are required for core business processes to meet the speed and flexibility requirements dictated by fast-changing markets. These paradigms should include the functionality to establish the formal business relationship required by the importance of these core processes. The business relationship should be established in an automated, electronic way in order to match the speed and flexibility requirements mentioned above. As such, it should considerably improve on the ineffectiveness and inefficiency of traditional contracting in this context. The result of the establishment should be a detailed electronic contract that contains a complete specification of the intended cooperation between organizations. Electronic contracts should contain a precise and unambiguous specification of the collaboration at both the conceptual and technological level. Existing commercial software solutions for business-to-business contracting provide low level of automation and concentrate solely on the automated management of the contract enactment. However, in the modern, dynamic, business settings, an econtracting system has to support high automation of the e-contract establishment, enactment, and management. In the thesis, the business, legal, and technological requirements for the development of a highly automated e-contracting system are investigated. Models that satisfy these requirements and that can be used as a foundation for the implementation of an electronic contracting system are defined. First, the thesis presents the business benefits introduced to companies by highly automated electronic contracting. Next, a data and process analysis of electronic contracting is presented. The specification of electronic contracts and the required process support for electronic contract establishment and enactment are investigated. The business benefits and data and process models defined in the thesis are validated on the basis of two business cases from on-line advertising, namely the cases of online advertising in "De Telegraaf" and "Google". Finally, the thesis presents a specification of the functionalities that must be provided by an e-contracting system. A conceptual reference architecture that can be used as a starting point in the design and implementation of an electronic contracting system is defined. The work in the thesis is conducted on the intersection of the scientific areas of conceptual information and process modeling and specification on the one hand and distributed information system architecture modeling on the other hand

Enacting global competition in local supply chain environments: German “Chemieparks” and the micro-politics of employment relations in a CME

Drawing upon the debate on institutional mediation of macro processes, we examine how multinational enterprises (MNEs) engage with global competition through restructuring their operations situated in local supply chain environments and how employment relations (ER) of coordinated market economies are reconfigured in the course of this restructuring process. Our empirical setting is the German chemical industry which is both an exemplar of coordinated labour-management-collaboration and highly exposed to global competition. Using a comparative case study design, we observe how MNEs re-structure two local production sites into ‘Chemieparks’. Our empirical data suggest that local agency diverges in the extent to which the social partnership type of ER is maintained or disrupted. Furthermore, we highlight the importance of micro-political practices for understanding the restructuring outcome as well as the local enactment and change of macro institutions within production networks as meso-level arenas for institutional mediation

Reasoning about Social Relationships with Jason

Abstract. This work faces the problem of enabling an approach to agent programming, which allows agents to seamlessly manage and work both on social relationships and on abstractions which typically characterize agents themselves, like goals, beliefs, intentions. A similar approach is necessary in order to easily develop Socio-Technical Systems and provides a basis for carrying on methodological studies on system engineering. The paper presents an extension of JaCa(Mo) in which Jason agents can reason on social relationships, that are represented as commitments, and where Jason agents interact by way of special CArtAgO artifacts, which reify commitment-based protocols
