The Fuzzy Comprehensive Evaluation Based On Rough Set Theory Technology Enterprise Quality Credit

At present, the enterprise quality technology credit deficiency in critical condition, enterprise credit evaluation become popular new subject, and against quality technology credit evaluation of the concern of the public. But at present the researches of evaluation index system and evaluation methods for enterprise quality technology credit are relative lack, and need continuous exploration and perfect. The main problem enterprise quality technology credit evaluation process facing is how to choose the scientific index system for objective evaluation. At present there is no unified standards and specifications, and the traditional evaluation method with poor objectivity is much subjective.A perfect enterprise quality technology of credit evaluation system helps scientific evaluation of enterprise quality technical level, accurately reflect the potential quality technology enterprise credit risk. Also help the government on economic macro regulation and maintain a unified, open, competitive and orderly market economic order. There are many factors affecting quality technology of credit evaluation system of the reasonable and scientific evaluation index. Omission or overlapping between information will affect the objectivity of evaluation results and accuracy. At present, the establishment of index system and information screening hasn't unified regulations and standards, most researchers according to the needs of the subjective evaluation to determine standard, cause ndividual subjective factors impact assessment system's effectiveness.In view of this, this article according to our country qualitative inspect branch work functions and content, provided the construction enterprise quality technology of credit evaluation system method based on rough sets of the attribute reduction and combining fuzzy synthesis evaluation.Rough set theory can process discrete digital information powerfully, and has the generalization ability, and to excavate the potential relationship between indicators, quantitative analysis attribute importance, and the sample distribution demand is not high. Based on reference existing enterprise quality technology credit evaluation theory and the predecessor's research results and practical experience foundation, according to our country enterprise at present development situation and qualitative inspect branch work contents, the article established in product quality, equipment management as primary index to include out of factory marking authentication and production rate, situation and so on secondary indexes of comprehensive evaluation index system. And introduces each index of specific functions and calculation method are given, through attribute importance each quality technology credit evaluation indexes weights. So avoid man-made subjective, makes the evaluation results more fair and reasonable.Finally the fuzzy synthesis evaluation method of evaluation of various factors on the synthesis, obtained a comprehensive evaluation results. In the fuzzy comprehensive evaluation process, to compare the enterprise with counterparts in other enterprises, quantitative evaluation index membership degree of certainty is using trapezoid subordinate function to analysis and calculation. Through the use case analysis verification results show that the method is effective and reasonable on the whole assessment.
