基于随机模型求解连锁零售业配送中心的选址问题

Solving the Location Problem of Chain Retailing Distribution Center Based on Stochastic Model

针对连锁零售业配送中心选址问题进行研究,通过随机变量停止—损失序的判断准则,建立随机变量数学模型。讨论随机变量数学模型相对于传统模型需求构造随机化方面的合理性,综合考虑运输费用以及由于食品腐败而产生的损失费用,建立费用目标函数。最后,通过重心法对目标函数进行求解,进一步验证该模型在物流配送中心选址的寻优能力和求解效率。

This paper studies the location problem of the distribution center of the chain retail industry,establishes the mathematical model of the random variable through the criterion of the stop-loss sequence of random variables,and discusses the rationality and cost savings of the mathematical model of the random variable compared with the traditional model. Establish a cost objective function by considering transportation costs and the cost of damage due to food corruption. Finally,the objective function is solved by the center of gravity method,and the model is further verified in the logistics distribution center. Optimization ability and solution efficiency.
