INVENTORY CENTRALIZATION IN AN ELECTRONICS RETAIL BUSINESS
研究了泰国EGR电子零售公司从直接分销转向集中配送中心（DC）系统对总分销成本的影响，发现DC系统能降低总成本，但运输成本的变化与预期相反。
This research examines the impact of changing a distribution system from a direct distribution system (from supplier direct to each store) to a DC system, in the EGR Company (a pseudonym), which is a multi location electronic retail company in Thailand. The DC system is an inventory centralization distribution system that centralizes inventory in one place for distribution to other locations. Each store keeps inventory only at safety stock level, most inventory being kept at a DC. The research statistically compares a three-month period of implementing a DC distribution with the same period of the previous year in order to eliminate the seasonal nature of the product sales volume. The total distribution cost consists of the average aggregated stock level, transportation cost, and inventory management and administration cost, and the researcher expected a reduction after the company implemented a DC system. Indeed the results did show that a DC system can reduce the total distribution cost. However, the results of the impact on transportation cost are surprising, as weighted sales volume transportation cost is reduced by a DC distribution system which is the opposite to what was expected.
