基于空间价格均衡的物流中心选址双层规划模型研究

空间价格均衡原理是商品出行普遍遵循的运输价格规律,在进行物流中心规划时,可以基于上述原理考虑商品需求量在各区域的分配情况。因此,本文建立了双层规划选址模型,上层规划从系统规划者的角度出发使选址总费用最小,下层规划为在考虑各物流中心相互影响的情况下的空间价格均衡的变分不等式模式。同时设计了启发式方法对上述模型进行求解。

RESEARCH ON LOCATION MODEL OF LOGISTICS CENTERS BASED ON SPATIAL PRICING EQUALIBRIUM

Spatial pricing equalibrium is the basic rule of transportation commodities. When planning the logistics centers, we can consider the distribution of the demand based on the above principle. A bilevel programming model is proposed in this paper, and the upper level problem is to minimize the total cost from the points of system planners, under the condition of the interactions between logistics centers, the lower level is a variational inequality based on spatial pricing equalibrium. At the same time, a heuristic algorithm is given to solve the model.
