基于GA-PSO算法的生鲜农产品选址-路径问题优化研究

摘要

According to thefresh agriculturalperishablecharacteristics,with the introduction of the intact rate function offresh agricultural product based on theperishable productlife cycle to express thetransportationcost of damage,fully considering thecost of transportation from the supplier to thedistribution center anddistribution center to the demand points of the goods,and combining theconcept of timeswindowto establish the location routing optimization model oftheminimum total costand the maximum, regarding theproblemas a whole todesign GA-PSOalgorithm, finally using examplesto verifythe analysis.%针对生鲜农产品易腐败的特性，引进以易腐品生命周期为基础的生鲜农产品完好率函数来表示运输途中的货损成本，完整考虑货物从供应商到配送中心及配送中心到需求点的运输成本，并结合时间窗的概念，建立了总成本最小、服务水平最大的选址—路径优化模型，并将该问题看成一个整体设计出GA-PSO算法求解，最后采用实例对其进行验证分析。
