基于路况的医药冷链物流配送路径优化

基于传统的医药冷链物流配送模型,在考虑道路通行状况对模型求解最优路径影响的基础上,建立了以综合成本为目标函数的配送模型.同时,将实际配送情况进行参数化数学建模,并通过一个数值算例,使用蚁群算法求解考虑道路通行状况的配送模型与未考虑道路通行状况的配送模型,将求解结果进行比较分析.结果表明:考虑路况条件的配送模型求解得到的最优路径比未考虑路况条件的配送模型求解得出的最优路径效果更优,综合成本降低11.96％,考虑路况条件的医药冷链物流配送模型具有更大的现实意义.

Optimization of pharmaceutical cold chain logistics distribution route based on road conditions

Based on the traditional pharmaceutical cold-chain logistics distribution model, considering the influence of road traffic conditions on the optimal path of the model, a distribution model with comprehensive cost as the objective function was established. Through a numerical example, the ant colony algorithm is used to solve the distribution model considering road traffic conditions and the distribution model without considering road traffic conditions, and the solution results are compared and analyzed. The results show that the optimal path obtained by the distribution model considering road conditions is better than that obtained by the distribution model without considering road conditions. The comprehensive cost is reduced by 11.96%. The pharmaceutical cold-chain logistics distribution model considering road conditions has greater practical significance.
