Abstract
There has been a great demand for the car replacement parts following an increase in car ownership. Needs for them range over various kinds of parts due to the changing of models. So it is an urgent task to develop an inventory contorl system for these replacement parts in order to supply them to users smoothly. In this study, physical distribution of replacement parts is regarded as multi-stage inventory control problem. We classify tens of thousands of replacement parts into classes based on their characteristics and design an inventory control system for each class.
