考虑促销的大规模定制库存系统动力学仿真

An Inventory System Dynamics Simulatioin of Mass Customization Considering Promotions

摘要:

在电子商务环境下, 促销信息快速传播, 产品需求产生显著波动, 使得大规模定制库存问题不再满足传统研究中的平稳性假设. 本文采用系统动力学方法, 用vensim软件构建了电子商务环境下考虑促销的大规模定制产品库存模型. 通过与非定制产品的比较分析得出, 尽管定制产品提高了库存总成本和库存水平, 但是可以获得更高的服务水平, 定制产品库存成本对补货启动成本的敏感性高于非定制产品, 而对产品成本、持货成本系数和缺货成本系数以及需求量变化的敏感性则较低.

Abstract:

Under e-commerce circumstances, because of the rapid spread of information of promotions, product demand fluctuates obviously, which makes the stationarity assumption in previous researches on the inventory optimization of mass customization no longer valid. Based on system dynamics, this research establishes the inventory model of the custom product considering the price-off promotions under e-commerce. The results show that although the mass customization costs more in inventory management, it could bring a higher level of service. The inventory cost of custom products is more sensitive about the set up cost and less sensitive about the product cost, holding cost, penalty cost and the product demand.
