Design of Optimal Maintenance Strategy

In the Gas Turbine Power Plant industry, the effective maintenance strategy will solve the fast cost-effective responses to unpredictable and ever-changing plant shutdowns. Continued pressure on companies to reduce costs and improve customer satisfaction has resulted in increasingly detailed examinations of maintenance strategies. A judiciously selected maintenance program can provide significant advantages in relation to quality, safety, availability, and cost reduction in these plants. A wrong decision can lead to the failure of the components and consequent economic losses. Therefore, justification of any given maintenance strategy within an organization must consider cost and other related criteria viz availability, criticality of machines (CM), maintenance support facility (MSF). The purpose of this study is to select the apposite maintenance strategy based on these criteria to improve the availability of power plant. The analytical hierarchy technique is used to come to the appropriate selection of maintenance strategy.
