    "abstract": "In this paper an analysis of the Stirling cycle in thermoeconomic terms is\ndeveloped using the entropy generation. In the thermoeconomic optimization of\nan irreversible Stirling heat pump cycle the F function has been introduced to\nevaluate the optimum for the higher and lower sources temperature ratio in the\ncycle: this ratio represents the value which optimizes the cycle itself. The\nvariation of the function F is proportional to the variation of the entropy\ngeneration, the maxima and minima of F has been evaluated in a previous paper\nwithout giving the physical foundation of the method. We investigate the\ngroundwork of this approach: to study the upper and lower limits of F function\nallows to determine the cycle stability and the optimization conditions. The\noptimization consists in the best COP at the least cost. The principle of\nmaximum variation for the entropy generation becomes the analytic foundation of\nthe optimization method in the thermoeconomic analysis for an irreversible\nStirling heat pump cycle.\n  Pacs: 89.65.G, 05.70 keywords: entropy generation, finite time\nThermodynamics, Stirling cycle, Thermodynamic optimization.",
