Abstract

This paper investigated the properties of discrete scheduled replacement model for a series-parallel system. The system have three subsystems, which are subsystems A, B and C. Subsystem A is having three parallel units, subsystem B is having a single unit, and subsystem C is having two parallel units. In this paper, it is assumed that, the system is subjected to two categories of failures, which are Category I and Category II failures. The mathematical expression of the reliability function is used in constructing the discrete scheduled replacement model for a series- parallel system, based on some assumptions. A simple illustrative numerical example was made available, so as to explore the properties of the discrete scheduled replacement model constructed.
