Abstract: The article at hands studies critically the development of the theory of Fuzzy Systems, its most common extensions and the main relative theories that have been introduced for managing the situations of uncertainty and vagueness or ambiguity appearing in Science, Technology and in the everyday life. The management of uncertainty in fuzzy systems in terms of the fuzzy probability and possibility is in particular discussed and examples are presented to illustrate the methods used for this purpose. The present work is important, because it offers a basic framework for those wanting to study deeper the above theories and the multi-valued logics connected to them that have found recently many and important applications to almost all sectors of human activity.
