Approximate Calculations of Maintenance Policies for Weibull Distribution Using Exponential Distribution
It is always easy to get analytical formulas of optimal maintenance policies with exponential failure times in reliability theory, however, it might be difficult sometimes to discuss them theoretically with a ...

Chapter
Replacement Policies with Independent Damages
In general, an operating unit degrades gradually with additive damage cumulated by shocks in a stochastic way.
-
Chapter
Other Maintenance Models
In order to conduct safe and economical maintenance strategy, modeling and analysis of the damage due to shocks in an analytical way plays an important role in reliability theory and engineering.

Chapter
Standard Replacement Policies
To begin with, this chapter gives three standard replacement models that have been obtained as basic replacement policies for an operating unit with shock and damage (Nakagawa Shock and damage models in reliab...

Chapter
Replacement Overtime and Middle Policies
Originally, replacement last was discussed to replace an operating unit without stop** successive working cycles by Zhao and Nakagawa (Eur J Oper Res 223:141–149, 2012, [7]); however, the approach of replacing ...

Chapter
Replacement Policies with Maintenances
Maintenance actions, such as preventive and corrective maintenances [1], minor and major maintenances [39], routine and non-routine maintenances [40, 41], etc., have been proposed in pairs in literatures.

Chapter
Database Maintenance Models
Database, a set of data and the way they are organized (Silberschatz et al. Database system concepts. McGraw-Hill Education, 2010, [51]), has now become the lifeblood for some organizations in this modern soci...

Chapter
Introduction
We take the reliability systems with repairs as examples to introduce the following stochastic processes briefly [3, 23].

Chapter
Replacement Last Policies
In theory, a new counter approach of whichever triggering event occurs last for the replacement policy with two PR scenarios should be considered rather than only the approach of whichever triggering event occurs...

Chapter
Replacement Policies with Repairs
In real situation, the damaged unit has probabilities of minor failures (or malfunctions) at shock times, in which case, minimal repairs that cost less are always considered to resume quickly the operation of ...
