摘要
优化商品交易市场选址方法有利于提升城市规划布局模式,促进城市有序发展。在分析现有选址模型在应用时存在不足的基础上,采用双层规划模型构建了商品交易市场选址模型。上层规划从决策者的角度出发,通过考虑修建商品交易市场的总费用与购买者需求量之间的关系,以使总的收益最大。下层规划描述使用者的选择行为,对应于最大效用值选择商品交易市场。同时,针对所建模型,设计了启发式求解算法,并以安徽省砀山县为例进行初步应用验证。
In this paper, the status of location of commodity exchange markets nowadays was analyzed firstly as an explanation why location of commodity exchange markets should be valued. Then, a bi--level programming model is presented to seek the optimal location for commodity exchange markets by considering benefits of customers and planning departments of commodity exchange markets. The upper level problem is to maximize the gross benefit from the terms of decision makers by taking account of the relationships of the total cost for building commodity exchange markets and user demand. The lower level problem describes the users＇ choice behavior. Finally, aiming at the model, a heuristic algorithm is designed, the feasibility of the model and algorithm is also verified by taking Dangshan as an example.
