The Model Research Of More Engineering Items Bid Decision Supporting System

Aim at the situation that more engineering item to provide to choose, we conceive to establish decision supports system as the basis of help decision. Focus all the faces in bid processing we should consider, we have designed obscured elements measure contrast model, bid game model, BP-net model, target plan model, similar engineering compare model, grey situation model, and so on. And have also researched the realization that model combination of usage to support decision and system structure.This thesis draws up the problem for resolve: for helping the enterprise decision, we build up support system assist the decision. Which models will be used for help the decision? How do these models combine to help the decision? Research route and the research methods of adopt is: settle the research method that quality and fixed amounts combine together, makes policy the basic principle and structures of support systems of currently as point to entrance, combine investigation of actual circumstance to the engineering biding, learning lessons from decision support system applicant in other professions, make decision supports to contact with engineering item biding, construct the engineering item biding decision support system model. Decision support system can give decider some excellent support suggestion, and the fruit of model research is very helpful to improve decision level, made the bid work actual effected and standard. This is the practical value and theories meanings of this thesis research.Each models face to concrete problem that should in consideration of biding process. Such as the best bring forth new ideal model: obscured elements measure contrast model use into the preliminary selection of engineering item;bid game model use into how to beat one's opponent;BP-net model use into analyze investigation affection base human nerve net theory;and so on.The realization of model combine is set studies that the logical relation betweens these models and computer assist decision technique.To this date, the usage of decision support system in engineering is a fresh thing, the usage that is in the aspects of bid have no mature result. Recently, our country and international experts mainly study bid theory and model in this domain, and have no ripe achievement. Therefore, the writing of this thesis also tries the challenge of once.
