连续型物流设施选址的区间决策模型及算法

Interval decision-making model and algorithm for continuous logistics facility location

考虑物流需求的不确定性,以区间数度量不确定性参数及变量,构建多商品、多节点的连续型物流设施选址区间决策模型,通过区间可能度判别区间解的性质与大小,设计问题求解的区间迭代遗传算法。算例测试结果表明,求解结果具有较强的实践可操作性,可以作为物流节点选址决策的参考方法。

In this paper,the uncertainty of logistics demand is considered.The interval number is used to measure uncertain parameters and variables.The interval decision-making model for continuous logistics facility location with multi commodity and multiple nodes is established.The properties and size of interval solution is judged by interval possibility,and the interval interactive genetic algorithm is designed to solve the problem.It is showed by a tested example that the research results have strong practical operability,and the method can be offered as an alternative for decision making for location of logistics node.
