Makeham’s Generalised Distribution

Abstract

The aim of this publication is to present a new probability distribution which for particular parameter values has a bimodal density function and a bathtub hazard rate function. All the main reliability properties of such distribution will be described in details in this paper. Such a distribution can constitute a very good mathematical model that would enable the description of the lifetime of technical devices. It can successfully be implemented in the planning of a burn-in procedure and a preventive maintenance of non-repairable devices. Key
