动态环境下基于换电模式的电动车路径问题研究
Research on the Path Issue of Electric Vehicles Based on the Power Swapping Mode in Dynamic Environment
摘要
Abstract
In the actual distribution,considering the vehicle speed is affected by different weather and dif-ferent time periods,according to the function relationship between speed and energy consumption of electric vehicles,with the objective of minimum total transportation cost composed of the fixed driving cost,energy consumption cost and time penalty cost of the electric vehicle,and with vehicle load,battery capacity,cus-tomer time window,and vehicle speed as constraints,a routing optimization model of electric vehicle based on power change mode and time-varying speed in dynamic environment is constructed.Genetic algorithm is used to solve the model with real number coding,roulette operator,random single point crossover,random varia-tion,and small variation rate to improve the local search ability,and then it is compared with several cases when the vehicle speed is constant.The experimental results show that the established optimization model is more in line with the actual situation,and can reasonably arrange vehicle departures and plan distribution paths and sequences,according to the customer and road network in the dynamic environment,so as to reduce the distribution costs,and provide a reference for logistics enterprises to operate vehicles and optimize their distribution.关键词
