Subject and Keywords:
We show how the basic Bellman and Zadeh’s (1970) model of multistage decision making (control) in a fuzzy environment can be extended to account for human perceptions concerning its basic elements, i.e. the fuzzy constraints and fuzzy goals, by introducing objective (related more to measurements) and subjective (related more to perceptions) fuzzy constraints and fuzzy goals. To illustrate the extended, perception based model, we present a fuzzy socioeconomic sustainable regional development model initiated by Kacprzyk and Straszak (1984), and further developed by Kacprzyk (1997), Kacprzyk, Romero and Gomide (1999), etc. The model may be viewed as as example of how fuzzy logic, or - more generally - the computing with words paradigm, can help devise new more human consistent, perception based models.
