In this paper, we propose a new approach to build a Virtual Enterprise software infrastructure that offers persistence, concurrent access, coherence and security on a distributed-shared data store based on distributed-shared memory paradigm.
This article presents the HOLOS System, a control architecture infrastructure to be applied on dynamic scheduling. It is knowledge based, open, distributed (multi-agent), flexible, integrated, object-oriented, extendible and modular. The architecture infrastructure supports the virtual manufacturing concept and, at the same time, allows the integration of existing equipment. Negotiation technique is applied for production resources allocation, which increases the control flexibility during a schedule generation, specially in the presence of disruptions. The Consortium concept is introduced as a support for improving several types of production flexibility of an enterprise. Finally, some implementation aspects are presented as well as current problems and advantages of HOLOS.
A literature survey on the topic of the impact of information technology on organizations revealed the interplay between the use of information technology and organizational design. In this paper an evolutionary constructionist view of the impact of information technology on organizations is presented. With this view, the information technology enabled organizational migration has three stages: knowledge link, transaction link, and business alliance link.
A federated database system (FDBS) is a collection of cooperating database systems that are autonomous and possibly heterogeneous. In this paper, we define a reference architecture for distributed database management systems from system and schema viewpoints and show how various FDBS architectures can be developed. We then define a methodology for developing one of the popular architectures of an FDBS. Finally, we discuss critical issues related to developing and operating an FDBS.
The support of real collaborative virtual enterprise (VE) scenarios sets forward particularly interesting challenges in terms of distributed information management, regarding the proper sharing and exchange of information among preexisting autonomous enterprises. In order to address these challenges, it is necessary to achieve a comprehensive analysis of advanced information management approaches that can be applied in VE platforms. In this context, this chapter provides a representative survey of several VE-related information management standards, technologies, and existing approaches that can be applied to support future VE infrastructures.
