Research on capacitated vehicle scheduling problem with fuzzy time window
具有模糊时间窗的有容积约束车辆调度优化问题研究*

For the fuzzy time parameter and capacity restrictes of vehicle in distribution,illustrated an earliness/tardiness penalty function based on trapezoidal fuzzy number algebra,singed distance and the interval numbers distance which had higher accuracy.Based on it,introduced a capacitated vehicle scheduling problem(VSP) model with fuzzy timewindow for minimized earliness/tardiness penalty,delivery mileage and vehicle numbers firstly.After that,based on particle swarm optimization(PSO)and genetic algorithm,prop...
