| Summary: | 碩士 === 國立東華大學 === 全球運籌管理研究所 === 94 === In order to improve the competitiveness of supply chain, companies should
consider integrating their inventory systems. It could reduce stock and cost of the
whole inventory. Therefore, the profit of the supply chain will be increased. Therefore,
Vendor managed inventory (VMI) is one of the modern methods to manage inventory
along supply chain. By using VMI, the overstock problem between members of
supply chain can be solved efficiently.
In our research, we consider a single-product two-echelon supply chain
contained a single supplier. Refer to the supply chain management model of Dong and
Xu (2002), we consider VMI with taking the backorder situation into account, hence
the retailer’s order lot size will be raised.
The model of Dong and Xu was only considered that the retailer is the leader;
however, we concern the driving power between supplier and retailer is balanced in
our research. On aspect of profit, we analyze the influence on inventory cost after
using VMI with appropriated system parameters and the differences and the
similarities between our results and Dong and Xu’s.
Based on cases, our analysis shows that it is beneficial to use VMI under the
following situation: the supplier’s setup cost is greater than the retailer’s ordering cost,
or the retailer’s holding cost is less than its backordering cost, or the product value is
less expensive, or the size of manufacturing batch. However, the profit of supplier
will be decreased after applying VMI.
