Study On The Integration Technology Of Combined Evaluation

A single method itself has a variety of different properties and applicability of evaluation methods, and in ensuring the accuracy and adequacy of the premise, using the appropriate combination of assessment techniques can complement each other, produced by a single method to reduce deviation, will help improve the accuracy of evaluation results. In this paper, we try to make a study on the integration issues of combined evaluation, so that we construct the integrated research framework of the combined evaluation methods initialiy on the base of a comprehensive literature review on the combined evaluation.This study is divided into three parts:the entire-phase-type combination of evaluation results, the entire-phase-type combination of evaluation methods, the phase-type combination.The second chapter is about some classified research on the entire-phase-type combination of evaluation results (the value of evaluation, order of evaluation and class of evaluation), we propose some improvements and new ideas to the rank method, Borda method, the plural validity etc., pointe out the problems in the application, and introduce two kinds of test by giving some numerical examples. The third chapter gives the connotation and denotation of the entire-phase-type combination, concludes the characteristics and integration of single method, compares similarities and differences between AHP-DEA, gray-fuzzy, fuzzy-DEA the three kinds of combinatorial approach and make comments. The fourth chapter is about the phase-type combination of methods and results, specifically includes the conditions and ideas of the non-dimensional combination, comparison and analysis for law of weights, the method of getting "importance weight"μ, the initial exploration of complex synthetic etc.The main innovations includes the following:1, Here the research framework is constructed from an integrated perspective, certain concepts are clarified, and a number of new ideas are made in all aspects of the combined evaluation.2, In the combination of the order of evaluation, we improve the relative rank method, demonstrate in detail in the application of Borda method in two aspects, and rise an improved idea.3, In the combination of the class of evaluation, we have a further study on the plural validity, and simplify the original discriminant conditions. Further more, this paper puts forward a new kind of index and examines its nature. 4, We point out the problems of the non-dimensional combination, and the complex synthetic methods are discussed.
