Fuzzy rule-based models: decision-making vs control

Fuzzy rule-based models play an important role both in control and decision-making. In the latter case because of decision-maker involvement, fuzzy inputs and outputs not only allowed but also required. In spite of such differences of these two problems rule-based models for decision-making are designed and implemented in the same way as in control. Some issues specific for rule-based decision-making models are discussed, including rule-base consistency.
