Research Of Model-Drive Complex-Large Group Decision Support System In Environment Of Network

The development of network technology and the extensive application of network technology in every industry or trade of society have brought deep influence on the one hand to working way and the thought way of entire society, have brought deep change on the other hand to the way of managing of enterprise and the management way of government affairs. The significant decision of operating and management of social organization gradually turns into group decision in network. However this kind of influence and change also make the group who participate in the decision become more and more complex, its scale is more and more large. Under network environment, the appearance of the complex large group has brought new content to traditional group decision and its support system. Based on the research of traditional group decision and its support system and combing the systematic key part "model drive", this paper has further studied the model-drive complex-large group decision support system in environment of network (MCLGDSS ), and put forward systematic architecture and function structure. The theory, method, developing technology and application way etc. of the system realization have been gone on thorough discuss, study, realization and application.The major works of the paper mainly includes following few aspects:( 1 ) The appearance background and its basic feature for complex large group in network environmental have been analyzed. The studying situation in present and developing tendency of each theory of the domestic and international group decision and group decision support system have been summarized and analyzed. By use of layer model theory, the basic thought route and systematic frame of the research have been put forward. Regard model-drive and complex-large group decision method as the footstone of the research, based on it, the process mechanism of the group decision and the architecture of the complex-large group decision support system in network environment have been studied and constructed. The systematic function structure, the realizing method of all the systematic functions, the systematic realizing method and application way have also been studied. These will offer support to carry out group decision for the social organizations of every industry or trade in network times.( 2 ) The research of model-drive methodOn the foundation of model demand of extensive analysis oriented decision problem solving, combing the fact of problem solving, explain the form of model existence, description and performing way. The solution of model scheme based on complex decision making problem solving has been proposed. The architecture of the model reuse has been established through decompounding a atom model ( single model ) into a method ( algorithm ) object and a data object which are formed a combination and compounding atom models (in which the longitudinal and lateral two methods are put forward ) come to establish model can put system and structure in an important position. At the same time, the model compound realization method based on multi-agents technology has been put forward. It forms the model-drive method in the group decision support system of the network environment.( 3 ) The research of complex large-group decision method in network environmentAccording to the characteristic of the complex-large group in network environment, it has been proposed to divide the solving process of decision making problem into two stages. In first stage, each decision member solves to form own decision scheme using model and knowledge, it is equivalent to the traditional individual decision support system. In second stage, the group opinions are synthesized to form group decision. On the synthetic method, a kind of new function formula has been put forward to be used to measure the clustered degree of two decision members. Based on this function formula, a clustering category algorithm of the complex-large group members has been designed. Furthermore, the preference vector of the complex-large group, the algorithm of group coherence index and the algorithm of group decision value have been designed. By use of above results, the final result of group decision making is be obtained. Further the multi-schemes large lroup lecision making is obtained. In order to make the process of group decision making to go on smoothly, the processing mechanism of group decision making has been designed which includes the device of processing process of group decision making and the device of clustering process of group members.( 4 ) The research of the architecture of complex-large group decision support system in network environmentIn the support of model-drive and decision making method of complex-large group, combing the characteristic and developing tendency of network, the layerstructure of the systematic platform has been studied using layer model theory. This platform is divided into three layers. It is the decision front layer, decision service layer and decision resource layer. To normalize decision process, the information flow of systematic built-in has been designed. The systematic function structure and the function modules of the each layer of the system have been designed. The decision globe control subsystem, data management subsystem, model management subsystem and knowledge management subsystem have emphatically been studied and designed, which includes the processing process of each subsystem and its function realization method. With this, form the architecture of complex-large group decision support system in network environment.(5 ) The research of system realization method and its application wayIn system realization method, the component configure and the component operation mechanism of group decision have put forward based on the component developing technology and multi-agents technology, and the gross structure of system component and its internal relation have been studied. According to the need of application system developing, the using way of system component in application system developing and the coordinative mechanism of each system component in solving of decision problem have put forward to make user to be able to quickly developing the application system with group decision function.(6) The empirical studySelect certain representative famous copper group company's overall budget management group decision support system as the empirical case. Through the form of project cooperative research, the demand of the copper group company's overall budget management group decision has systematically been analyzed. The gross structure of overall budget management group decision support system of the group's key enterprise "Copper stock corporation" has been designed, in which the group decision basic condition and decision members have been explained. The group decision process and systematic function structure has carefully been designed. The realization method of every subsystem has carefully been studied. Through system developing, the result shows that the expectant effect has been reached.
