带有交易费用和持有成本的局内采购管理模型竞争分析

Competitive Analysis of Extension Model of Online Procurement Management

采购管理是企业经营活动的一个重要组成部分,更加有效的采购管理策略可以大大减少采购费用,对于企业的经营业绩非常重要。在现实的经济活动中交易费用和持有成本在企业管理费用中占很大一部分比率,而采购过程影响着交易费用和持有成本。所以在前人研究的基础上,将交易费用和持有成本引入到局内采购管理模型中,使得运用该策略无论以后采购价格如何变化,局内人的采购成本总是对应局外问题最优采购成本的一定比例c之内,并得到c与原模型相同。但是引入交易费用和持有成本后每天的采购量将发生变化,原模型是在不考虑交易费用和持有成本的前提下得得到的每天采购量和最优竞争比,如果考虑到现实经济活动中不可忽略的交易费用和持有成本,仍然按照原模型来确定每天的采购量来采购就不能得到最优竞争比c。所以本文考虑到了交易费用和持有成本,并得到和原模型不同的每天采购量,并求出最优竞争比c。

procurement management is an important part of the business activities, and more effective procure- ment management strategy can greatly reduce procurement costs, which is very important for the enterprise＇ s business performance, in the real economic activity inventory cost and commission cost accounts for a large part of the enterprise management costs, the procurement process affects the inventory cost and commission cost.

No matter what is the procurement price , the online player is promised to get a procurement cost about certain proportion c to the offline optimal procurement cost by committing the pro- curement policy proposed in the paper, and c is the same with the original model. But after the introduction of inventory cost and commission cost the amount of purchasing will change every day. The original model get pur- chase quantity and the best competitive ratio every day without considering the inventory cost and commission cost. If considering inventory cost and commission cost that cannot be ignored in real economic activity, we will not get the best competive ratio if still in accordance with the original model to determine the daily procurement. So this paper considering the transaction cost and holding original model, and find out the best competitive ratio c.
