Application of TOPSIS Method for Maintenance Planning: Natural Gas Combined Cycle Power Plant Case Study

Abstract

Economy and efficieny are one of the basic components of a sustainable energy policy. In this context in the scope of this study, the principle of reducing the electricity generation costs through effective maintenances in addition to the positive effect of maintenance planning on energy efficiency are based and an application has been performed in a natural gas combined cycle power plant effects the Turkey’s security of energy supply directly. In this application, criticality levels of the equipments in terms of power plant have been calculated under 9 criteria by using TOPSIS methodology, considering the multi objective and multi criteria nature of the maintenance planning problem and the necessity of taking into account the risks of the equipments in terms of the systems, and 9-years maintenance and a labor requirement plans are obtained.
