Abstract

In the course of improving and/or designing an energy system, either purely economic criteria, although the overriding criteria, or purely energy-based criteria, although the emphasized criteria, can not separately handle real-world situations in a satisfactory manner. The economic effectiveness and the energy efficiency must be considered simultaneously to demonstrate the conflicting and non-commensurable characteristics of these multiple criteria.

An iterative and interactive approach to formulating and solving non-linear multi-criteria decision making problems for the analysis of an energy system is proposed. It allows the decision maker (DM) to learn from the available information and dynamically change his mind. Criterion functions can be treated as objective functions, as constraints or as something in between by the DM. After a series of iterations and interactive procedures, a preferred solution can be made among the non-inferior sets considering thermodynamic criteria and economic criteria simultaneously. A simple example for design of a heat exchanger is used to illustrate the procedure.
