...Akbar Alem Tabriz; Behrooz Khorshidvand; Ashkan Ayough Purpose – The purpose of this paper is to present age-based replacement models subject to shocks and failure rate in order to determine the optimal replacement cycle. As a result, according to system reliability, maintenance costs...

... of the example considered in this paper is divided into three regimes, decreasing, constant and increasing failure rate, and the q-Weibull model describes the bathtub curve displayed by the data with a single set of parameters. Practical implications – The simplicity and flexibility...

... and an application to a practical example. Findings The q‐Weibull distribution function is able to reproduce the bathtub shape curve for the failure rate function with a single set of parameters. Moments of the distribution are also presented. Practical implications The generalized q‐Weibull distribution...
