An estimate of maintenance efficiency in Brown-Proschan imperfect repair model with bathtub failure intensity
Abstract: 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.
Keywords: repairable system,
