摘要

中文摘要
在擁有高單價的設備及零件產業，其因為考慮到公司的服務率或是其供應商的供給能力，往往過度庫存零件或設備。為了使得廣大地區的顧客都能得到一定的服務水準，此種高單價產品的製造商多使用多階層存貨系統。除了供應鏈體系中、上下階層的存貨制度合作下，同階層的廠商若能互相分享備用件，彼此間支付適當的側面供給成本，進行側面供給，將可更快速回應顧客的需求，降低整個供應鏈架構的存貨水準及成本。在以往的側面供給文獻當中大多為多階層存貨，單一維修階層且側面供給的時間假設為零或者很小。本研究擬放寬其假設，探討一個二階層可維修的二階存貨系統，除此之外更發展一套啟發式演算法來尋求最低成本的系統最佳配置。並對影響模式的因子作探討，結果顯示在系統提供可維修、可側面供給及存貨混合選取的條件下能得到最低成本。

In the industries with high valuable equipment spare part are often reserved overly in order to provide the higher service rate to customer. For serving customers better in a wider area, the manufacturers utilize a multi-echelon inventory system. Besides the cooperation between the high level and the low level in a spare part supply chain, if the same level users can share spare parts with each other by paying reasonable expense, it can response the demand more quickly and decrease the total cost. In the last few years, several articles have been devoted to the study of lateral supply. They often assume the multi-echelon inventory system with a single repairable echelon and lateral supply time is zero or small. This study intends to release these assumptions to develop a two-echelon lateral supply inventory model for repairable items. In addition, a heuristic method is developed to find the optimal solution in terms of inventory allocations in the spare part supply chain system. Moreover, factors of repair probability, lateral supply, and inventory allocation are studied, the optimal solution with the lowest cost occurs at considering repair at the user level, allowing lateral supply, and allocating inventory between depot and users.
