Abstract

This study aims to formulate a strategic decision-making framework for accelerating periodic overhaul duration in coal-fired power plants without compromising operational reliability. This issue is critical because prolonged overhaul duration in the Jamali-area coal-fired power plant fleet is associated with a decline in the Equivalent Availability Factor (EAF). This study adopts an applied qualitative design by integrating SWOT analysis, the Analytical Hierarchy Process (AHP), Internal Factor Evaluation External Factor Evaluation (IFE/EFE), and the TOWS matrix. Data are designed to be collected through in-depth interviews, pairwise-comparison questionnaires, field observations of overhaul activities, and reviews of performance, outage, operating procedure, and procurement documents. The main outcome is a four-stage framework for identifying internal-external factors, assigning priority weights, evaluating strategic position, and formulating overhaul acceleration strategies. The proposed SWOT AHP framework enables management to prioritize critical factors, including maintenance planning, spare-part readiness, contractor coordination, and resource allocation, thereby improving decision-making effectiveness and strategic focus.
