The provisioning of expensive equipment and corresponding
spares is the fundamental activity of suppliers in high-tech
industry such as semiconductor manufacturing. The equipment is
often critical to the manufacturing processes in wafer
fabrication, and their unavailability may lead to excessive
downtime cost. As a result, the procurement of reliable
equipment and the provisioning quality of repairing service are
important to semiconductor industry. Therefore, the service
level of spares may affect the sales of equipment and it is one
of the most important performance indices for equipment supplier
in this environment. Due to the high procurement cost, the
inventory cost constitutes a large part of investment for
equipment supplier. The increase of inventory turn will be an
important mission as well. Therefore, how to increase inventory
turn under a satisfied service level is a critical issue in this
industry.This research proposes a decision support procedurles
adjustment, safety stock determination for each parts, and
reasonable lead time for each part to beat second-source
competitors and to attract more demand are also discussed.
