摘　　要：针对电子中介中卖方对多数量的商品交易存在数量折扣的情形,研究了具有数量折扣的多属性商品交易匹配问题。首先,给出了新的买卖双方多属性商品交易匹配度的概念和计算方法,并且确立了卖方商品的数量折扣曲线。然后,以最大化买卖双方加权匹配度为目标,建立了电子中介中具有数量折扣的多属性商品交易匹配模型,并根据模型的非连续和非线性特点,设计了嵌入混沌扰动的捕食搜索算法对模型进行求解。最后,通过多个实例的计算,并与遗传算法进行对比分析,结果表明模型与算法是可行和高效的。With respect to the seller＇s quantity discount for multiple units of commodity,the purpose of this paper is to study the multi-attribute trade matching problem with buyers and sellers in electronic brokerage environment.Firstly,based on the curve of quantity discount of commodities from sellers,the new definitions and calculational methods of trade matching degree from both buyers＇ and sellers＇ points of view are given.Secondly,a mathematic model is built to maximize matching degree with its weight.Then,according to the non-continual and nonlinear characteristics of the model,a predatory search algorithm with chaos is proposed to solve it.Finally,computation on simulation examples and comparison with genetic algorithm shows the model and algorithm are feasible and effective.
