Application of fuzzy sets in the processing of linguistically expressed uncertainty

In connection with the progressive introduction of highly automated manufacturing systems and CIM systems, much attention in the last two decades has been paid to the investigation of the potential formalization of manual, routine-mental and partly also creative human activity (operator, dispatcher, designer). There has been a search for software tools that achieve individual results like the ´real´ human expert mainly on the basis of symbolic considerations with the use of heuristic procedures. Decision support systems and expert systems appear to be very effective tools in the realization of the obtained algorithms and formalized decision making procedures.
