【Abstract】 In this paper a fuzzy job shop schedule problem model is presented in order to deal with the uncertain processing time. Based on fuzzy set theory and fuzzy decision theory, two fuzzy operators are used and a feasible algorithm is constructed for assigning different membership values to different objective functions. Finally, simulation results are given to illustrate the efficiency of the proposed fuzzy schedule model and algorithm.更多还原
