Distribution location routing optimization problem of food cold chain with time window in time varying network
时变网络条件下带时间窗的食品冷链配送定位—运输路径优化问题

In order to solve the problem of food cold chain logistics distribution system optimization problem, for perishable goods characteristics, combined with the distribution network time-varying characteristics to analyse travel time, this paper designed satisfaction degree function according to service time windows and established the simulation model under time-dependent. It designed the two-phase solution of preoptimization phase and real-time optimization phase, by using the decomposition method, it decomposed the problem, designed the minimum envelope clustering analysis method and tabu search algorithm to solve the problem. Simulation results show the effectiveness of the model and algorithm of practical value.
