The Research Of The Model Base In GDSS

Nowadays, problems which people face are lager and more complicated then before, and are out reach of people' s decision-making ability. To avert mistaking decision, co-working is usually needed in important decision-making. GDSS is supported to settle such questions.MBMS is one of the key techniques in GDSS. How to denote a model, how to organize a model and which function a MBMS should provide, those questions are keys in developing a GDSS.The paper enters on the theories of GDSS. It sets forth the concept, the character, the aim and the support function of a GDSS, as well as component, category, characteristic, fundamental construct and advance developing of GDSS. The paper analyses the Model Base of GDSS, introduces the concepts of model and Model Base and its denotation, and modeling demands. It totally analyses the MBMS, includes its central research content, its structure, its function and interface between Model Base and Data Base. Two-dimensional frame theory in Model Base is introduced aimed at the problems existed in developing MBMS.This paper makes a preparatory research on the Object Oriented GDSSMB. The theory of Object Oriented Method is recommended and exerted in building and administrating of MBMS, and a OOMBMS is presented, which is helpful in developing and applications MBMS.Finally, the article makes a preview of Model Base in GDSS.
