Cool Chain Logistics Distribution Routing Optimization for Urban Fresh Agricultural Products Considering Rejection of Goods

Fresh agricultural products are essential necessities for daily life of urban residents. With the continuous improvement of urban residents' the living standards, the development of internet technology and e-commerce in China, fresh product e-commerce provides a new channel for urban residents to purchase fresh agricultural products. In this new way, urban residents pay more attention to the quality of fresh agricultural products. Therefore, the problem of distribution routing optimization in this emerging mode needs to consider not only the choice of the route, but also the impact of temperature on product quality, energy consumption during distribution, and customer's rejection due to poor quality of delivered goods. A distribution routing optimization model is established comprehensively considering those mentioned factors, and a numerical example is carried out by using genetic algorithms to solve the problem and testifies validity of the model.
