农超对接基地选址建模分析

Mathematical modeling of base location for farmer-supermarket direct-purchase

农超对接是农产品基地与市场对接的主要模式。为了减少流通环节,降低流通成本,针对零售连锁农产品需求具有不确定性的特点,将零售连锁的需求表示为模糊变量,建立了两阶段模糊最小风险农超对接基地选址模型,使生产基地的运行费用和基地到零售连锁的运输费用总和不超过给定水平的可信性最大。实例证明,模型及求解方法具有较高的准确性和实际应用价值。

Farmer-supermarket direct-purchase is the main mode of integration of agricultural market and base. In order to reduce circulation link and cost, regarding the uncertainty of the demands for retail agricultural products, the paper expressed the demands of retail chain as fuzzy variables, and established a two-stage fuzzy risk minimization farmer-supermarket direct- purchase base location model, to maximize the credibility that the sum of base operation cost and delivery expense from base to retail chain does not exceed the given level. Experimental re- sults show that the approximation scheme is very accurate and has valuable application .
