基于运筹优化的河南省农产品供应点选址问题研究

Research on the Location of Agricultural Products Supply Points in Henan Province Based on Operations Optimization

摘要: 河南省农产品供应点选址问题以供应点覆盖人口数最多、所花费的租赁费用最低为目标函数，以相邻区县关系为约束条件，建立了农产品供应点选址的多目标整数线性规划模型，采用约束法、线性加权法这两种方法对其进行求解，并对权重的选取进行了讨论，依此结果可以对农产品供应点选址进行统筹优化，降低农产品的销售与运输成本，缩短物流时间，保证农产品的质量。

Abstract: The problem of location selection of agricultural supply points in Henan Province takes the maximum number of population covered by the supply points and the lowest lease cost as the objective function, and the relationship between neighboring districts and counties as the constraint condition. The multi-objective integer linear programming model of location selection of agricultural supply points is established. The two methods of constraint method and linear weighting method are used to solve the problem, and the selection of weights is discussed. According to the results, the location of supply points of agricultural products can be optimized as a whole, so as to reduce the sales and transportation costs of agricultural products, shorten the logistics time and ensure the quality of agricultural products.
