...Francis K.N. Leung; K.K. Lai This paper reports on the application of the sequential method, presented in a previous paper by Lai et al. in 2001, to determine optimal strategies of when to carry out a preventive maintenance action for an engine and when to replace an engine in use...

...Frank Beichelt The purpose of this paper is to propose, motivate and discuss a policy for optimal scheduling replacement intervals of technical systems only on the basis of maintenance cost parameter: a system is replaced by a new one as soon as the maintenance cost within a replacement cycle...

...K.B Bahrami‐G.; J.W.H. Price; J. Mathew The subject of investigation reported in this paper is the determination of an optimal replacement time for equipment that deteriorates with time. The following hypothesis is proposed and investigated. While a piece of equipment is in the final stages of its...

... inflation rate and failure rate variation after maintenance, an algorithm of balanced maintenance scheduling is developed. The algorithm provides an optimal number of replacement and preventive maintenance to minimize the total maintenance cost over a certain planning period. A numerical example...
