不完备信息系统的梯形模糊数三支决策模型
Trapezoidal Fuzzy Number Three-way Decision Model for Incomplete Information Systems
摘要
Abstract
In the incomplete information systems,combined with the Bayes decision theory,this paper used the complete tolerance relation improved in literature [3] to replace the equivalence relation of classical decision rough sets,and introduced the generalized and easily calculated trapezoidal fuzzy numbers to the decision rough sets.Based on the incomplete information systems,a trapezoidal fuzzy number decision-theoretic rough set model was proposed.And the three-way decision rules were then presented,and the different decision rules for the pessimists and optimists were discussed,respectively.Finally,an example was given to illustrate the application process of the proposed model.关键词
