摘要：

为有效克服服装零售商面临多款式产品难以决策的困难,基于模块化生产的服装产品组合进行优化决策,构造了模块化生产模式下的服装时尚度函数;基于消费者效用最大化,构建确定型需求的产品组合决策模型和零售商利润模型;设计了关于垂直差异化服装产品之间的有向图来优化产品集合,以最短路径求得零售商利润最大化的产品组合;研究了市场上多个零售商与供应商之间的利润分配问题。研究结果表明:利用有向图优化零售商的服装产品组合决策问题,其效果明显优于穷举法;该方法将提高服装零售商和供应商的决策水平,获得最大化利润。

关键词: 模块化生产, 服装产品组合, 垂直差异化, 利润分配

Abstract:

In order to address the difficulty in making decisions for multi-style products faced by garment retailers, an optimization decision process was studied based on the garment product combination of modular production, and the garment fashion degree function under the modular production mode was constructed. Based on the maximization of consumer utility, a demand deterministic consumer choice model and a retailer profit model were established. The directed graph between vertically differentiated clothing products was designed to optimize the product set, and the product portfolio with the shortest path to maximize the retailer's profit was obtained. In addition, the profit distribution between multiple retailers and suppliers in the market is also discussed. The results show that the effect of using directed graph to optimize retailers' clothing product portfolio decision-making is obviously better than that of the exhaustive method. This method is expected to improve the decision-making level of garment retailers and suppliers and maximize profits.

Key words: modular production, apparel product portfolio, vertical differentiation, profit distribution
