Abstract
Purpose
The reliabilities of systems are generally improved as units of redundancy increase. This paper aims to summarize the authors' results.
Design/methodology/approach
A conceptual discussion and approach are taken.
Findings
Focuses on the optimal number of units and replacement times of parallel systems, two modified replacement policies and two maintenance policies where a system is replaced at Nth repair and Nth failure. Further, as some examples of redundancy, five redundant models of data transmission, checkpoint, network and copy are given, and optimal policies for each model are analytically discussed.
Originality/value
Presents the number of units and replacement times of parallel systems, and other modified replacement and preventive maintenance policies.
