-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.

“…Establishing the reliability of structures resulting from the analysis of electrical systems installed on board of aircrafts can be achieved by direct calculations, but involves a long working time as a result of taking into account all possible situations that can occur during system operation (Reus, 1971), (Hoang Pham ,2003), (Levitin, G. et al, 1997).…”

“…The ROP for the multi-state reliability was introduced in [9]. In [10] and [1], genetic algorithms were used to find the optimal or nearly optimal power system structure. In [11] the multi-stage expansion-planning problem for multi-state series-parallel system is solved by using a genetic algorithm as an optimization tool.…”

“…When applied to electric power systems, reliability is considered as a measure of the ability of the system to meet the load demand (D), i.e., to provide an adequate supply of electrical energy ( ). This definition of the reliability index is widely used for power systems: see e.g., [16][17][18] and [1]. The loss of load probability (LOLP) index is usually used to estimate the reliability index [19].…”

Usually power energy demand increases randomly with time. To enhance system performance, expansion-planning to adapt the power system capacity to the demand is predicted. This paper uses a harmony search metaheuristic optimization method to solve the multi-stage expansion problem for multi-state series-parallel power systems. The study horizon is divided into several periods. At each period the demand distribution is forecasted in the form of a cumulative demand curve. A multiple-choice of additional components from a list of available products can be chosen and included into any subsystem component at any stage to improve the system performance. The components are characterized by their cost, performance (capacity), and availability. The objective is to minimize each investment over its study period while satisfying availability or performance constraints. A universal generating function technique is applied to evaluate power system availability. The harmony search approach is required to identify the optimal combination of adding components with different parameters to be allocated in parallel at each stage.
