Xie Daowen · Computer Engineering and Applications Journal · 2013
Because of the special characteristics of goods and materials to coal enterprise,supplying goods quality of suppliers,speed of delivery,service quality and so on are essential to work safety.So,scientific and reasonable choice of suppliers is imperative for coal enterprise.On the basis of evaluation index system,which is developed in other paper,some index weights are re-determined by the uncertainty reasoning method:the cloud theory.Soft classification is used to determine evaluation grade of suppliers in this paper,not adopting traditional hard classification.A new cloud evaluation model is developed by normal cloud generator and backward cloud generator.A case study is demonstrated to check the validness of the proposed model,which presents useful information.
