A Study On The Bid-Evaluation Model And Method Based On Set Pair Analysis Theory

With the rapid development of our country's economy and the requirements of international practice, bidding has become an important act of the market economy. People first put forward the tender requirements and conditions of goods, works or services procurement, large number of bidders are invited to take part in the tender and can select the transaction object in accordance with established procedures from the selection of trading partners. In the work of bidding, the evaluation is the most important link, the fair and reasonable is key to the success of the work of bidding, Only a reasonable evaluation of model-based, objective description of the relationship between uncertainty and certainty, and take appropriate treatment methods, then the evaluation of bidding for the comprehensive strength of all tender units is reasonable and fair and choose the successful bidder.Comprehensive Evaluation of the evaluation is to establish an effective evaluation model and a reasonable weight to determine the evaluation method is the key. This article will be set on the analysis of multi-link, the link weights of the introduction of number theory to identify and comprehensive evaluation to determine a new index weight representation and integrated evaluation model.Fuzzy comprehensive evaluation method is a method that is commonly used for comprehensive evaluation, but indicators of degree of membership is sometimes difficult to determine for the problem of evaluation. This article will set pair analysis theory with the introduction of different anti-fuzzy comprehensive evaluation method, using contact-degree portrait of ways to replace the membership degree to describe, so that factors of uncertainty more reasonable interpretations; at the same time established the evaluation degree of four-element connection expression and for the cost, income and middle-program indicators linked to form a new degree of determination, so as to establish the SPA fuzzy comprehensive evaluation model, its general fuzzy comprehensive comparative study to clarify its advantages. And examples show that it is simple and effective to the problem of evaluation. In the process of evaluation, it is sometimes difficult to express the weight of evaluation index value, so this article links in the multi-link binary difference a few degrees based on the set pair analysis theory for the problem, first the right to reuse such three parameters express interval number, and then on this basis will be translated into a binary number of differences in degree of connection number. Then the method has been applied to the comprehensive evaluation, the complete evaluation model of more comprehensive differences in degree is given by using the fuzzy comprehensive evaluation, and the method is applied to the evaluation and found that it has certain degree of practical value.
