Efficient and on-time maintenance plays a crucial role in reducing cost and increasing the market share of an industrial unit. Preventive maintenance is a broad term that encompasses a set of activities aimed at improving the overall reliability and availability of a system before machinery breakdown. The previous studies have addressed the scheduling of preventive maintenance. These studies ha...

We consider a single-machine scheduling problem with periodic maintenance activities. Although the scheduling problem with maintenance has attracted researchers’ attention, most of past studies considered only one maintenance period. In this research several maintenance periods are considered where each maintenance activity is scheduled after a periodic time interval. The objective is to find a...

This paper presents a Harmony Search Algorithm to seek the optimal solution of the unit maintenance scheduling. For the maintenance scheduling, cost reduction is as important as reliability. The objective function of this algorithm considers the effect of economy as well as reliability. Various constraints such as spinning reserve, duration of maintenance crew are being taken into account. We a...

Maintenance scheduling of generating units is considered one of the vital power system problem for providing power in a reliable and economic way. In order to improve the overall availability of the generating units, chances of capacity shortage is to be reduced by performing preventive maintenance at regular intervals. In this paper, Hybrid integer coded Water Wave Optimization (HWWO) Algorith...

Despite the promising outlook, numerous economic and environmental benefits of offshore wind energy are still compromised by its high Operations Maintenance (O&M) expenditures. On one hand, offshore-specific challenges such as site remoteness, harsh weather, transportation requirements, production losses, significantly inflate O&M costs relative to land-based farms. other uncertainties in weath...
