An estimate of maintenance efficiency in Brown-Proschan imperfect repair model with bathtub failure intensity

Makram Krit, Abdelwaheb Rebai

Abstract


Purpose: Estimate the maintenance efficiency in the Brown-Proschan model with the bathtub failure intensity.

Design/methodology/approach: Empirical research through which we propose a framework to establish the characteristics of failure process and its influence on maintenance process.

Findings: The main contribution of the present study is the reformulation of the Brown and Proschan model using the bathtub failure intensity

Practical implications: Our model is defined by BP reformulation one using bathtub failure intensity. This form of intensity is presented like superposition of two NHPP and Homogeneous Poisson one.

Originality/value: This is the follow on research on the study that employed the power-law-process type of failure intensity.
