Traducción del resúmen del autor: The paper deals with the exergoeconomic optimization of a gas turbine system. A parallel between thermoeconomic and exergoeconomic optimization is carried on. It is pointed out that exergoeconomics offers additional capabilities in optimization that are not available with the conventional technic optimization. The goal of exergoeconomic design optimization of an energy systems is to find the structure and the values of the system parameters that minimize the cost of final products considering restrictions imposed by the desired reliability, maintainability, operability and environmental impact of the system, using local or global exergetic parameters.
