冷链物流优化模型构建

Establishment of Cold Chain Logistics Optimization Model

主要从分析冷链物流所运输的冷链产品特点出发,首先考虑冷藏(冻)车装载冷链产品货箱或冷藏(冻)箱的问题,根据目的地的实际需求,考虑到棱"相似"、面"相似"、体"相似"或棱"相等"、面"相等"、体"相等"情况,利用等价替换,构建了其他装载方案模型;其次是冷藏(冻)车的派发问题,并把目的地分为终点性目的地和中转性目的地来进行分析,建立了冷链配送优化模型;最后,通过对江苏中洋集团的实际调研,验证了所建模型的合理性与正确性。

In this paper, from the characteristics of the cold chain products transported in the cold chain logistics process, we first considered the carton packing problem of the refrigeration trucks, then according to the practical demand of the destination and considering the situation of similar cartons or identical cartons, relied on prevalence and substitution to build other packing solutions and models; next, we studied the dispatching of the refrigeration trucks, divided their destinations into final destination and intermediate destination, and built the corresponding cold chain distribution optimization model; at the end, through an empirical investigation of the Jiangsu Zhongyang Group, we demonstrated the validity and correctness of the model established.
