摘要
[摘妻]针对冷链物流运输路径选择问题,通过在恒温条件下推导食品腐败率与时间的非线性函数关系,建立损失函数和冷链物流节点选址模型,探讨了利用遗传算法对选址模型求解的分析方法,并通过一个典型实例证明了此方法的正确性和可行性,为冷链物流选址工作提供了一个有效可行的方式。
In this paper, with regard to the selection of transportation route in cold-chain logistics, we deduced the non-linear functional relationship between food spoilage rate and time under constant temperature, formulated the loss function and the location model of the cold-chain logistics nodes, discussed how to solve the model using the genetic algorithm and at the end through an empirical example demonstrated the validity of the method.
