A prospect theory based MADM method for solar water heater selection problems

摘要

Recently, the solar water heaters have been widely used in China. For common consumers, the solar water heater selection problems have theoretical and practical significance. In this paper, a multiple attribute decision making method for solar water heater selection problems is proposed. Firstly, the evaluations to alternatives take the form of linguistic terms and then are transformed into triangular fuzzy numbers. Secondly, the reference points of the attributes are obtained from the decision maker. Then, based on prospect theory and the operation rules of fuzzy numbers, the linguistic rating information is converted and aggregated. Finally, the alternatives are ranked from best to worst. The first one is the optimal choice. The availability of the proposed method is illustrated through an application in solar water heater selection problems.
