Abstract: In order to solve the route selection problem of electric vehicles in the process of cold chain logistics distribution in time-varying road network, according to the characteristics of cold chain products and electric refrigerated vehicles, the multi-fuzzy time window constraints and the distribution vehicle power constraints are introduced, and the electric refrigerated vehicle route optimization model considering the multi-time window constraints of charging stations in time-varying road network established. The AP clustering algorithm is used to divide the distribution area, and the improved genetic algorithm used to solve the model on the basis of clear distribution range. The validity and feasibility of the model and algorithm are verified by a simulation example. The distribution schemes under static network and time-varying network are compared, and the universality of the model is verified by randomly generated cases of different scales. The results show that compared with the static road network, the distribution scheme based on time-varying road network can reduce the distribution cost by 12.201%. The research results have certain guiding significance for helping enterprises to plan the distribution route scientifically and reduce the distribution cost.
