چکیده

In this study, a combination of different vehicle routing problems called Vehicle Routing Problem with a Time Window and Stochastic Demand has been examined. The difference between previous papers and this paper is that in our problem, the competitors compete with each other to meet the demands of customers in a specific industry. It seems that these problems occur in real life as well. In most real environmental problems, customers materialize their utmost demand for a vehicle that reaches on time and sooner than other competitors. The target function is to maximize the profit earned through the sale of goods to customers. Solving the research model in several trivial problems has been made precisely by using GAMZ Software.
