     this work presents a computational approach for the simultaneous minimization of the total cost and environmental impact of thermodynamic cycles. our method combines process simulation, multi-objective optimization and life cycle assessment (lca) within a unified framework that identifies in a systematic manner optimal design and operating conditions according to several economic and lca impacts. our approach takes advantages of the complementary strengths of process simulation (in which mass, energy balances and thermodynamic calculations are implemented in an easy manner) and rigorous deterministic optimization tools. we demonstrate the capabilities of this strategy by means of two case studies in which we address the design of a 10 mw rankine cycle modeled in aspen hysys, and a 90 kw ammonia-water absorption cooling cycle implemented in aspen plus. numerical results show that it is possible to achieve environmental and cost savings using our rigorous approach.
