Research On Integrated Technologies Of Virtual Enterprise Information System

Under the model of agile manufacturing, the single market competition situation is changing gradually. With the individuation and diversification of customer' demands, more and more enterprises can't seize the transient market opportunity independently by the merge of one's own resources, which will be difficult to meet the fast changing market demand. So, many enterprises strengthen the competitiveness of organizing through setting up Dynamic Alliance (Virtual Enetrprise) to improve the competitive power.The efficient operation of virtual enterprise can not do without the support of information systems. Compared with traditional enterprise, the characteristics of the virtual enterprise such as timeliness, dynamic, distribution, ntegration, autonomy and heterogeneous, which have propsed the new challenges for the integration of the virtual enterprise information system. Taking the information intergration of virtual enterprise as the background, this thesis has studied several key technologies which support the intergration of virtual enterprise, and analysed its features and limitations. Finally, from the view of mergeing the technologys of Web Services and Agent, the thesis has designed a Web Services-based Multi-Agent integration model of virtual enterprise information systems, and expatiated the interactive processes of internal components.The main researches accomplished in this thesis are as follows:1. Through the definition of virtual enterprise and its characteristic, the thesis has analysed the challenges proposed by the characteristics of virtual enterprise, and the characteristics of virtual enterprise integrated system.2. Based on the description, analysis and comparision of the enabling technology, the thesis has proposed a Web Services-based integrated framework of virtual enterprise information system, and analysed its features and limitations.Finally, improve this model form the perspective of use Ontology in terms of knowledge integration.3. Analyse the similarities between virtual enterprise and multi-agent system and built a Multi-Agent system architecture.Based on consultation and negotiation mechanism of agent, the thesis has described the set-up procedure of virtual enterprise, and analysed the characteristic and limitation of multi-agent system for virtual enterprise information system integration.4. From the perspective of mergeing the technologys of Web Services and Agent, combined the ideas of workflow, the thesis has proposed a Web Services-based Multi-Agent integration model of virtual enterprise information systems, and expatiated the interactive processes of internal components.
