Resumen
In this paper, we introduce an optimization strategy in order to comprehensively quantify the impact of
availability and maintenance notions during the early stages of synthesis and design of a new natural gas
combined cycle power plant. A detailed state-space approach is thoroughly discussed, where influence of
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 which may 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 of resources assigned for maintenance
actions are varied across a wide range of feasible values, which enable obtaining more accurate and
detailed estimations of the expected economic performance for the project when compared with traditional economic evaluation approaches. Fil: Godoy, Ezequiel. UTN. FRRo.
