ABSTRACT This paper Study the reliability and availability characteristics of the system with PM and CCF. The failure times , replacement times, PM times and CCF times of a components are assumed to be exponentially distributed. We derive the mean time to failure( MTTF) and the steady state availability( ) in this system. Some Special cases have been studies theoretically and graphically to obs...

This paper considers a repairable system which undergoes preventive maintenance (PM) periodically and is minimally repaired at each failure.

In this paper, we consider the situation where each PM relieves stress temporarily and hence slows the rate of syst...

This paper is to propose a two-stage preventive maintenance (PM) policy for the multi-state deterioration system under periodic inspection and with multiple candidate actions for PM. Such policy is mainly to schedule PM optimally and also on how to choose the action optimally for each PM. The scheduling includes two tasks: to determine after completing each PM when to make the decision and then...

Over the years, there has been an advancement in how manufacturing companies conduct maintenance. They have begun transitioning from Preventive Maintenance (PM) to Predictive (PdM). With introduction of technologies such as Digital Twin (DT), Internet Things (IoT), and Intelligent Manufacturing (IM), world is rapidly changing, thus allowing optimise existing processes, products reduce costs. Th...

In this study, by integrating preventive maintenance (PM) into a two-dimensional warranty region, with customized PM (2D PM) is proposed from the manufacturer’s perspective to reduce cost. The cost of 2D derived. tradeoff between and minimal repair saving obtained choosing proper reliability threshold number PMs, advantage illustrated. Second, post-warranty period, bivariate (BPWM) policy consu...
