博士 === 國立交通大學 === 工業工程與管理學系 === 100 === In this study, we develop inventory models for manufacturer to determine the key component order quantity under a buyer minimum-commitment quantity contract. Under the contract, the buyer is required to commit a minimum order quantity θ1 for returning the buyer’s commitment to the manufacturer who is also required to guarantee to supply θ1(1+r), where 0 <r <1. Besides, the manufacturer provides a shortage compensation policy to compensate the buyer for shortage if his supply is below θ1(1+r). We consider two scenarios under the buyer minimum-commitment quantity contract: (i) the upstream supplier offers the manufacturer a flexible supply quantity and a quota to place his rush order; and (ii) the manufacturer has two placing order points, however the unit price in his second order is uncertain. Under above-mentioned scenarios we formulate inventory models for determining the key component order quantity to maximize the manufacturer’s profit, respectively. We also propose solution procedures for the models, respectively. Finally, Numerical examples are given to illustrate the proposed solution procedure and sensitivity analysis are performed to find managerial insights.
