Research Of Material Circulation Management Decision Support Systems

This paper discusses the theory and the technology method which applied to the Corporation Material Circulation Management Decision Support System, and discusses applications at the aspect of the decision analysis such as WEB' s data base application technology, data warehouse application technology, data mining application technology and intellect dispatch technology etc. in detail, and mixes together with the mentioned above technology together, and form the enterprisedecision analysis environment.The application of WEB's data base technology: The electronics Material Circulation Management that three layers of model CLIENT/SERVER on the base of WEB is applied to the enterprise flows in managing the system design, and makes the system possess maintenance that the flexibility is unassuming, and has received better applying effect , and has provided the complete data source for the material flow decision analysis in the back.The application of data warehouse technology: The data warehouse architectural structure, method of designing data warehouse, method of building model and the effect in the policy decision support system of data warehouse etc. have been probed into. Unique advanced method of SAS 8. 2 analytic systems in establishment and management of data warehouse has been studied comparatively in detail. The SAS system has an ability initiatively going to take the outside data, so taking out the data from data source according to the rhythm of time and coordinating with other system manager on the good foundation, can make the plan of every system have been taken the data in SAS system completely. On the basis of this, the data warehouse, according to requirement of the data and information' s using time, is loading ontime and upgrading. It is the important characteristic of SAS data warehouse technology that the operation of integrated type formed a coherent whole from the data source to the data warehouse .The application of data mining technology: Having studied the method that the application of the data mining under the SAS 8.2 software system environment: The data are initiatively taken out from the various data source, and cleared up and combined; And then dividing themes, recombining the data according to the need of decision support; Constantly automatically loading and upgrading data warehouse according to the rhythm of time sequence; The decision analysis is carried on with the rich data handling tool ; Finally the analysis result of decision supported appears to user with many kinds of forms.The research of The intelligent dispatch Sub system: As an auxiliary function of policy decision supported system, I am according to the production run circumstances, and has developed the intelligent dispatch algorithm, and run on WEB, and is used in the day-to-day production scheduling to manage. The intelligent dispatch algorithm of material flow studied in this paper adopts service state space to describe the whole dispatch process. It establishes dispatch command model according to this, adopts the mechanism of data-driven, according to the service state change of the operating course controls running of the dispatch serves operating. It has realized dispatches intellectuality and automatizition. This algorithm is passed the improvement, and it still can be applied to the other fields that can describe the question with the state space.
