This paper makes attempts to perform multi-objective optimization on the solar-powered Stirling engine
with high temperature differential. A new model was proposed based on the finite-time thermodynamic.
Furthermore, the thermal efficiency of the solar Stirling system with a rate of finite heat transfer, regenerative
heat loss, the output power, finite regeneration process time and conductive thermal bridging loss
is specified. The thermal efficiency, entransy loss rate and power output have been maximized simultaneously
for a dish-Stirling system and entropy generation’s rate in the engine minimized via using thermodynamic
analysis and NSGA-II algorithm. To specify the optimum values of the above mentioned
parameters three well known decision making methods have been employed. Finally, an error analysis
was applied on the outputs gained from each decision makers.
