Study On Intelligent Decision Support System Of Virtual Enterprise Based On Semantic

In recent years, with the rapid development of Internet, network technology and network information system, the Virtual Enterprise is to flourish at an unprecedented rate when it is on a theoretical level no long ago. Practice has proved that network information technology can be applied to enterprise information management by Virtual Enterprise. It can organize different competitive advantage through effective network platform and achieve common goals at a high degree of division of labor in low-cost transactions. The core competitiveness of enterprises and integrated efficiency can be greatly enhanced by the Virtual Enterprise.But, with the growing number of members joining Virtual Enterprise and the continuous increase in the amount of information network of Virtual Enterprise, the complicated information is searched more and more hard. Under this circumstances, only depending on the clicking amount of statistical information or traditional sense of the information retrieval can hardly supply useful information to deciders from not only Recall Factor but also Pertinency Factor, even can increase the burden on enterprises. Information Retrieval based on semantic can provide an effective solution from Recall Factor, Pertinency Factor, similarity and etc. because of it basing on semantic concept.In order to do this, we construct a semantic retrieval based on the Virtual Enterprise Intelligent Decision Model using Semantic Retrieval Technology on the basis of understanding of the organizational structure, business processes and information systems of Virtual Enterprise, and realize it to provide a new way to support decision-making to business organizations. This paper has carried out the following work:(1) Virtual Enterprise intelligent decision systems theory. At first, it describes the concept of the semantic retrieval, virtual enterprise, intelligent decision support system and other related knowledge. And then, it deals with the advantages of semantic retrieval than traditional information retrieval, organizational structure and mechanisms of Virtual Enterprise and Information system of Virtual Enterprise etc. At last, it spawns intelligent decision support system in Virtual Enterprise.(2) Architecture of Virtual Enterprise intelligent decision model based on semantic model. From the current domestic popular model based on the semantic model theory retrieval, it presents the semantic retrieval model of domain model in virtual enterprise and discourses its general structure, building of domain object and implementation of retrieval. Finally, it builds the Virtual Enterprise intelligent decision model base on semantic model.(3) System design. First of all, it analyzes system demand and necessity analysis and puts forward the ideas of building the Coal Virtual Enterprise intelligent decision system. Sitting down here, it introduces the system development method and development tools, system architecture and functional module analysis.(4) System data warehouses design. It quotes the data warehouses theory at first. It highlights the business management module data warehouses design and semantic management module data warehouses design. At last, it introduces collaboration management module database design.(5) Prototype system realization. In the first place, it briefly introduces the Software Engineering involving description of system integrated software and hardware. Afterwards it focuses on the realization of software system, including setup of network operating system, setup and configuration of JDK, integration and configuration of Apache and Tomcat, configuration of development environment, realization of system Common Block, realization of business management module, realization of intelligent semantic retrieval, realization of intelligent decision module and etc. Through above work, it designs the Coal Virtual Enterprise Intelligent Decision Systems. It can be done data processing, treatment, statistics, analysis and forecast to Coal Virtual Enterprise and provides decision support for managers.
