摘 要:文章针对冷链物流运输问题建立了优化模型,使得冷链物流运输过程中的碳成本、时间窗的惩罚成本以及货物的变质成本总和最小,再运用改进蚁群算法,对其信息素浓度做出新的更新规则,避免了求解较慢和陷入局部最優解的问题;文章最后应用模型求解,得到最优路径和最低成本。

Abstract: This paper establishes an optimization model for the cold-chain logistics transportation problem to minimize the total cost of carbon cost, penalty cost of time window and deterioration cost of goods in the cold-chain logistics transportation process, and then uses the improved ant colony algorithm to make a new update rule for its pheromone concentration, avoiding the problem of slow solution and falling into local optimal solution. Finally, the model is applied to obtain the optimal path and the lowest cost.

Key words: cold chain logistics; optimization model; time window; improved ant colony algorithm
