Optimal post-warranty maintenance policy with minimal repair for a continuously monitored system in non-renewable warranty period
Miri Yoshizawa, Nobuyuki Tamura (Hosei Univ) R2023-50
Abstract (in Japanese) (See Japanese page) 
(in English) This study considers a post-warranty maintenance policy for a product which degrades according to an Inverse Gaussian (IG) process and is continuously monitored over the non-renewable warranty period. The product is repaired whenever it reaches a threshold given in advance within the period and is returned an initial level. At the instant that the warranty is expired, we reduce the degradation level and the age of the product through a hybrid PM, respectively. After the PM, the product is operated without continuous monitoring under a block replacement with minimal repair. For the product, we derive an expected cost rate by using the theory of renewal reward process. Then, we discuss on an optimal replacement time which minimizes the expected cost rate through numerical analysis.
