基于道路状况的冷链物流配送路径优化

Cold Logistics Distribution Path Optimization Based on the Condition of Road Traffic Situation

文章以一般冷藏物流配送路径模型为基础,考虑道路状况对冷链物流配送成本的影响,以包括制冷成本、运输成本、货损成本、违反客户时间窗的惩罚成本在内的总成本为目标函数,建立了基于道路状况的冷链物流配送模型。在算法上,构造了基于道路状况的综合节约算法,并对10个客户进行算例分析,用该算法分别对考虑道路状况的冷藏配送模型和一般冷藏配送模型求解。由结果可知两个模型得出的最优路径不同,说明了考虑道路状况的冷藏配送问题的必要性。

In this paper, we have established the cold chain logistics and distribution models based on the analysis of the general path of refrigerated logistics model, which taking into full consideration of the impact of road conditions on cold chain logistics and distribution costs including cooling costs, transportation costs, cargo damage costs, and the cost of punishment in violation of the customer time with total cost for the target function. In the algorithm, based on the road conditions we make a comprehensive conservation to have a test for 10 clients to make a specific analysis of the road conditions, which is a generally cold refrigerated distribution model and distribution model for the algorithm. Checking with the results of the two models, there is a great differ- ence in two optimal path, which just suggest it has a great necessity to consider the refrigerated distribution problems of the read conditions.
