Abstract: This paper deals with the supermarket logistics distribution problem with time windows in an uncertain environment. The daily demands of supermarkets and travel times of vehicles are treated as uncertain variables. In order to minimize the total travel time of all the vehicles, an uncertain chance constrained programming model is constructed. Then the proposed model is converted into a crisp equivalent model by operational law of uncertain variable. Moreover, an algorithm for solving the model is designed. Finally, a numerical example is presented to illustrate the modeling idea.
