The Study On Appraising Model In Construction Engineering

With the development of market economy and the need of the international situation, Tendering and bidding has been the main means of distributing engineering project. The core link of tendering and bidding is that the best one has been selected from all the bidders with a reasonable appraising method. The appraising methods used often can't describe the relation of determination and disdetermination in the appraising process so that information probably has been lost or repeated. Connection degrees of intensity have been set up to show the relation of determination and disdetermination by Set Pair Analysis in the two important links of evaluation _the determination of norm importance and the foundation of appraising model. In the connection degrees of intensity, determinational information has been used to build norm importance and show the good-bad relation of every plan. And disdeterminal information has been used to indicate the changing tendency of every norm importance. The subjective disdetermination has been overcomed. In order to reflect the real strength and the difference of all the bidders, A set of norms has been built up based on the practical situation and the principle about norm determinations. And what's more, they have been standardized by appropriate nonlinear functions so that the difference of all the bidders can be manifested. In order to test the appraising model, the model built up in this paper has been put into the particular project. The insufficience has been analysed and summed up.
