Abstract
Most of the European countries have implemented large renewable energy systems that use wind energy, solar energy and water
energy. In our country only water energy was used for many years. In the last period there is an obvious orientation towards the
use of all types of renewable energy systems, which are both efficient and environmental friendly. The objective of our paper is
to design an instrument for the evaluation of the best suited renewable energy system for different areas and type of use.
Generally, the evaluation is made using some kind of expert system (ES) based on general rules. The novelty of our approach is
the integration of the Quality Function Deployment (QFD) method in this evaluation process. The main advantage of the use of
QFD method is that it offers a means to globally evaluate the best suited renewable energy system based on the specified
requirements and the quality characteristics of the available systems. The QFD based expert system is validated by evaluating the
best suited types of wind turbines for several different areas.
