Research on Electric Vehicle Distribution of Multi-class Emergency Materials with Mixed Time Windows
In order to further improve delivery efficiency and reduce delivery costs,a cross cycle hybrid time window delivery method is proposed for multiple types of materials.Taking the minimum total delivery cost as the objective,considering vehicle path constraints,delivery time window constraints for very urgent and general emergency materials,vehicle charging constraints,etc.,an optimization model for the delivery path of electric vehicles for multiple types of emergency materials is established,and a model solving algorithm is designed based on genetic algorithm.In the example,a comparative analysis was conducted on the situation with or without priority and soft time windows.By comparing the optimal path formed and the satisfaction rate of customer points,it was shown that the model in this paper can achieve the minimum total cost and higher customer satisfaction rate for the distribution of emergency materials under emergency conditions.
