| Abstract | Due to the current epidemic situation that is COVID-19, most people are changing behavior to be the new normal that is mostly staying at home and making us turn to online platforms to order and deliver. including ordering fresh food and ready-to-eat food. That makes us interested in the way how to deliver products to customers by using vehicle routing problems to organize the shortest route for the delivery which has a requirement to deliver fresh food products that should keep at a low temperature to maintain the temperature and reduce the rotten product before it reaches to the customer. That brings us to the vehicle routing problem in cold chain systems, this paper creates a mathematical model with the goal of minimize total distance. A vehicle routing problem with adding load in each node based on the sweep algorithm with load distance that designs solutions to solve the problem and plan which route should select to routing to reduce the total distance.Computational results on the dataset by excel solver compare with CPLEX solver in terms of problem-solving ability and find the optimal route for delivery Python. |
