Optimal Warranty Period for Repairable Goods

수리가능(修理可能)한 제품(製品)의 최적(最適) 사후보증기간(事後保證期間)의 설정(設定)

This paper discusses the methods of determining optimal warranty period for repairable goods. The demand of the product is assumed to increase with the length of the warranty period. Good-as-new repair and minimal repair models are considered. The method of obtaining optimal warranty period is explored when the failure distribution is an exponential or a Weibull. The case of discounting all associated costs continuously over time is also considered.
