-This paper combines the universal generating function UGF with harmony search (HSO) meta-heuristic optimization method to solve a preventive maintenance (PM) problem for series-parallel system. In this work, we consider the situation where system and its components have several ranges of performance levels. Such systems are called multi-state systems (MSS). To enhance system availability or (reliability), possible schedule preventive maintenance actions are performed to equipments and affect strongly the effective age. The MSS measure is related to the ability of the system to satisfy the demand. The objective is to develop an algorithm to generate an optimal sequence of maintenance actions providing system working with the desired level of availability or (reliability) during its lifetime with minimal maintenance cost rate. To evaluate the MSS system availability, a fast method based on UGF is suggested. The harmony search approach can be applied as an optimization technique and adapted to this PM optimization problem.

“…This concept was first discussed by Murchland (1975), and the question of MSS reliability has since been developed extensively. Important early achievements (up to the mid-1980s) have been reviewed by Natvig (1985) and by El-Neweihi and Proschan (1984), and Lisnianski et al (2010) performed a comprehensive analysis of MSS. These systems can also be studied using Markov and semi-Markov models , Li et al (2017), Peng et al (2017)).…”

In this paper, we try to solve the Redundancy Optimization Problem (ROP) using a recent bio-inspired meta-heuristic that is Firefly Algorithm (FA) combined to Universal Moment Generating Function (UMGF).The problem consists on selecting the appropriate components from a multi-state system (MSS) given the minimum cost. The solution must also fulfill a system reliability constraint. The reliability in our work is considered as the ability to satisfy the demand and is calculated using u-tranform technique. Our algorithm was tested on a system contained multiple choices of five subsystems from a list of product available in the market. The components of each subsystem are characterized by their cost, performance (capacity) and availability. The results obtained by the proposed algorithm are compared with several algorithm founds in literature.
