Exergy – Aided Cost Optimization Using Evolutionary Algorithms

In this paper an algorithm is presented, which combines a powerful optimizing tool, Evolutionary Algorithms, with an exergo-economic analysis. The latter supports the optimizer by evaluating certain parameters as the exergetic efficiency and the relative cost difference. A simple cogeneration system has been chosen to illustrate this algorithm. This paper was presented at the ECOS’00 Conference in Enschede, July 5-7, 2000
