考虑分段线性成本函数的多仓库选址模型及求解算法

在考虑规模经济的因素下,以最小化项目的供货成本、运输成本与固定成本之和为总目标建立了一个多仓库选址模型,其中把供货成本用分段线性函数表示,体现了厂商存在的规模经济效应,并采用遗传算法对模型进行求解。最后通过一算例来验证模型及其算法的可行性和有效性。

Location Model and Solution Algorithm for Multi-warehouse Based on Piecewise Linear Cost Function

Based on the factors of mass economy,the paper establishes a multi-warehouse location model which takes the sum of minimized supply costs,transport costs and fixed costs as the goal and within which supply costs are expressed by piecewise linear cost function,solves the model with a genetic algorithm and shows an example.
