Credibility Model of Newsboy Problem with Discrete Fuzzy Demand
Based on the theory of credibility, the expected cost and profit models for determining the order quantities of newsboy problem with discrete fuzzy demand are presented, and are compared with a model based on centroid eigenvalue of possibility theory. The results are shown that: 1)the corresponding order quantities of minimum fuzzy cost and maximum fuzzy profit are not equal to each other, and the determinate order quantities of fuzzy expected model and centroid eigenvalue model are not equal to each other, neither; 2)with various order quantities,the sum of fuzzy possibility cost and profit and the sum of expected cost and profit are not constant. Because corresponding to probability measure, the description of fuzzy variable in fuzzy sense is credibility measure. So, the fuzzy expected models of newsboy problem with discrete fuzzy demand are better than fuzzy possibility models by compare.
