The Role of Fuzziness in Decision Making

摘要: In this paper we discuss the true objective of fuzzy decision making models. particular, stress that models should focus their attention on processes, instead referring to final output a decision, which is crisp act. fact, while Probability Theory can properly model acts, not case for decisions. But in fact human beings manage poorly defined arguments and alternatives, what usually call always ill defined, although still expect they produce consistent acts as consequence. These being with previous are somewhat unpredictable, extremely dependant specific circumstances at moment an act required by makers. Therefore, many cases pursuing consistency these subsequent may be misleading. The main issue principle check between those behind them, formalized. sometimes unrealistic, since there few chances repeat experience. We also our led us such decision. This relevant role fuzziness making, viewed support problem (acts supported arguments).
