Based Materials Management Decision Support System In The C / Sb / S Mode

DSS is the new phase of the development of the MIS.lt supplies the decision-makers with necessary information so as to help them to make important decision and improve the decision's accuracy.The application foreground is very broad.As part of MMDSS.model base,method base,database and man-machine subsystem is designed according to the theories of N-tier,c/s and b/s.It also adopts very popular COM/DCOM technology to accomplish the system.The process is devided into some phases.which advances the development schedule and improve the system's efficiency and effective.This article firstly introduces the concept, characteristic and structure of DSS.In the second chapter ,the whole modeling process is described,which uses the modeling tool named ROSE developped by Rational company. In the third chapter,the system's structure,developping tool and environment and developping method are refered.from the fourth chapter to the seventh one.this article emphatically discusses the analyse ,design and achievement of every part of DSS.MMDSS has already been adopted by the Second Oil-field Construction Company of Daqing Oil-field, which has got good economy benefit and social benefit.
