In reliability engineering literature, a large number of research papers on optimal preventive
maintenance (PM) of technical systems (networks) have appeared based on preliminary …

In the past several decades, maintenance and replacement problems of deteriorating
systems have been extensively studied in the literature. Thousands of maintenance and …

The maintenance of a deteriorating system is often imperfect: the system after maintenance
will not as good as new, but younger. Imperfect maintenance study indicates a significant …

Many serious accidents have happened in the world where systems have been large-scale
and complex, and have caused heavy damage and a social sense of instability …

This book aims to present a state-of-the-art survey of theories and methods of reliability,
maintenance, and warranty with emphasis on multi-unit systems, and to reflect current hot …

New, global and extended markets are forcing companies to process and manage
increasingly differentiated products with shorter life cycles, low volumes and reduced …

Many systems are required to perform a series of missions with finite breaks between any
two consecutive missions. In such a case, one of the most widely used maintenance policies …

Reliability, Maintainability, and Supportability play a crucial role in achieving a competitive
product. While manufacturing costs are important for the success of a product, they are not …

This paper proposes a generalized replacement policy where a system has two types of
failures and is replaced at the n-th type I failure (minor failure) or first type II failure …

Minimal repair and perfect repair, discussed extensively in the reliability and maintenance
literature, represent two extreme types of repairs. Many repair or maintenance activities may …
