Research And Realization Of Decision Support System Generator

Decision Support System(DSS) gradually develops on the basis of Management Information System(MIS).Based on the model base and database, it uses quantitative way to aid decision making. It can increase the efficiency of the decision and improve the management of the system. Currently DSS has already been the research hotspot of the information field.The development of traditional DSS is a very hard and complex process, so it's very wise to design a main frame and select an effective tool to develop a decision support system . Decision support system generator(DSSG) is just designed for this requirement. It can provide kinds of software component .So it is a convenient and strong development environment.With regarding to the development of decision support system generator, model-base system is one of the key technologies of DSSG. This paper has studied and compared the representation methods of expression of model-base system and done some work as following:At first, the author compares and analyses the existing representation of model in detail, and brings forward the standardization of model.Then , the author discusses the orient-object method of design , and brings forward the design of the structure of DSSG and its sub components on the base of OOP .At last, the detail realization of DSSG using orient-object method was introduced simply according to the practices of the author.
