Study On Combination Evaluation Computer Support System Based On Method Set

Study on Computer Support System for combination evaluation based onmethod set, will not only help perfect evaluation theory from methodology, butalso promote expansion of the application of comprehensive evaluation method.There are two prominent problems existing in the studies of comprehensiveevaluation both at home and abroad now: the first one is the inconsistency amongthe evaluation conclusions drawn by different evaluation methods; the second oneis the disjointedness between theoretical research and practical application.Moreover, as to the study on support system for evaluation, there are someevaluation softwares, but they are dispersed and isolated. There isn't supportsoftware on combination evaluation. This study is intended to find an effectiveway to resolve two above-mentioned problems. The main contents and results canbe summarized up as follows: A more reasonable indicator standardization method, called as modifiednormalization method, is proposed to make full use of advantages and preventdisadvantages by comparing and analyzing the frequently-employed indicatorstandardization methods. The drift about the evaluation conclusion of single method is studied inorder to offer the experiment basis for combination evaluation. Firstly, theevaluation problems are divided into 3 categories. Then evaluation objects that aregenerated by Matlab6.5 are evaluated by using different methods. Thirdly, thecompatibility of the comprehensive evaluation methods is identified after thestandardization of the evaluation results. Finally the average of the compatiblemethods is taken as reference frame to quantitatively measure the drifting degreeof each method. Convergence of combination evaluation is studied through simulationexperiment to resolve inconsistency among the evaluation conclusions drawn bydifferent evaluation methods. In this experiment, stochastic simulated data andpractical examples data are used respectively to simulate the combinationevaluation and re-combination evaluation of different kind methods. The resultsindicate that combination evaluation converges very well. After several times ofcombination, combination evaluation results can reach consistency rapidly, thusconsistent evaluation conclusions are obtained. Based on the introduction of computer evaluation system requirementsanalysis, general design, indicator standardization methods, the methods of weightdetermination, single comprehensive evaluation methods, the model fordetermination of compatible method set, the model for measurement of drift aboutthe evaluation conclusions of single methods, combination evaluation methods 1Abstractand convergence of combination evaluation, a computer support system forcombination evaluation based on method set is developed to resolve two urgentproblems existing in the comprehensive evaluation research field. This systemoffers three different process models and corresponding user interfaces. Thesystem is mainly programmed using Delphi7.0, with the aid of MATLAB6.5, toimplement human-computer interface. The methods and models are composed asM-file by MATLAB6.5, and the data are saved in MATLAB data file.
