Resumen:
In this paper, we introduce an optimization strategy in order to comprehensively quantify the impact ofavailability and maintenance notions during the early stages of synthesis and design of a new natural gascombined cycle power plant. A detailed state-space approach is thoroughly discussed, where influenceof maintenance funds on each component?s repair rate is directly assessed.In this context, analysis of the reliability characteristics of the system is centered at two designer-adopted parameters, which largely influence the obtained results: the number of components whichmay fail independently at the same time, and the number of simultaneous failure/repair events.Then, optimal solutions are evaluated as the availability-related parameters and the amount ofresources assigned for maintenance actions are varied across a wide range of feasible values, whichenable obtaining more accurate and detailed estimations of the expected economic performance for theproject when compared with traditional economic evaluation approaches.
