Fuzzy sets programming to perform evaluation of solar systems in Jordan

This paper uses fuzzy set methodology to perform the comparison between different solar systems for various applications. The aim of the paper is to determine the order in which solar systems should be given higher priority to be used in Jordan. The systems considered are solar distillation, solar water heating, solar space heating and ventilation, solar water pumping, photovoltaics and solar electric power production. They were compared according to their benefits and costs. Based on benefit to cost ratios, the results show that solar distillation is found to be the best choice and should be given the highest priority in terms of research and development. It is followed by the solar pond for electric power production, then, solar water pumping followed by solar space heating and photovoltaics. Finally, solar water heating may not need further development. (C) 2001 Elsevier Science Ltd. All rights reserved.
