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。
Aiming at the situation in which the quantity of discounts for the quantity of commodities traded by the seller in the electronic intermediary exists, the matching problem of the quantity of commodities with the quantity discount is studied. First, the concept and calculation method of the matching degree of the new buyer-seller multi-attribute goods transaction are given, and the quantity discount curves of the seller’s goods are established. Then, with the goal of maximizing the weighted matching degree between buyer and seller, a multi-attribute trade matching model with quantity discount is established. According to the discontinuous and nonlinear characteristics of the model, a predator-prey search algorithm with embedded chaotic disturbance is designed Model to solve. Finally, through the calculation of multiple instances and comparison with genetic algorithm, the results show that the model and the algorithm are feasible and efficient.
