生鲜农产品冷链物流车辆配送路径优化研究

Optimization Study on Vehicle Distribution Routing of Cold-chain Logistics for Fresh Agricultural Products

针对生鲜农产品易变质、易腐蚀的特性,探索冷链物流配送路径的优化方法。首先通过对固定成本、运输成本、货损成本、惩罚成本和能耗成本的研究,建立了以总成本最小为目标函数的农产品冷链物流车辆配送路径优化模型,然后采用改进的蚁群算法对模型进行设计,最后通过实例分析,运用MATLAB软件编写算法程序,求解结果验证了设计的模型的合理性和可行性。

In this paper, the optimization method of cold chain logistics distribution route is discussed for the perishable, easy to corrosion characteristics of fresh agricultural products. Firstly, through the study of fixed cost, transportation cost, damage cost, penalty cost and energy consumption cost, the paper establishes the optimization model of cold chain logistics vehicle distribution route of agricultural products with the total cost as the objective function.And then the improved ant colony algorithm is used to design the model. Finally, through the case analysis the MATLAB software is used to write the algorithm program, and the results verify the rationality and feasibility of the model.
