摘要

The purpose of this paper is to explore the inventory control problem with immediate return for defective items in fuzzy senses. First, the crisp case of the proposed model is constructed in terms of annual profit. Based on the features of the model and its practical applications, three parameters in the model: the perfective rate, demand rate and purchasing cost are fuzzified. The Yager's ranking method for fuzzy numbers is then utilized to determine the optimal order quantity. Due to the fact that triangular fuzzy numbers are used extensively, we also provide an expression of the optimal order quantity for the case that all of the three parameters are triangular fuzzy numbers. Finally, based on 125 combinations of triangular fuzzy numbers of the parameters, a numerical example is provided to illustrate the proposed model and assess the effects of fuzziness of the parameters on the optimal solution.
