FUZZY is an extension of the knowledge engineering environment (KEE) and provides the ability to reason with uncertainty within it. Through an appropriate rule syntax and semantics, FUZZY is fully integrated into the concept of the forward chaining engine of KEE. Thus, fuzzy facts and fuzzy rules can be easily combined. FUZZY reflects the necessity of representing uncertain knowledge and reasoning with it. FUZZY has already been successfully applied both in the synthesis and in the diagnosis domain and is a promising approach for knowledge engineering tools.<<ETX>>","PeriodicalId":117336,"journal":{"name":"[1991] Proceedings of the IEEE/ACM International Conference on Developing and Managing Expert System Programs","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1991-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127003092","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Both imprecision of temporal measurements and uncertain temporal knowledge are taken into consideration. Various causes of temporal uncertainty or fuzziness are discussed. On the basis of fuzzy set and possibility theory, each temporal uncertainty is represented in terms of possibility distributions. Definitions of temporal relations between two fuzzy temporal elements are proposed, and a computational model for combining different uncertainty bodies is described in order to compute the fulfilment degree of a generalized propositional statement under uncertainty. Fuzzy temporal constraint propagation is discussed.<<ETX>>","PeriodicalId":117336,"journal":{"name":"[1991] Proceedings of the IEEE/ACM International Conference on Developing and Managing Expert System Programs","volume":"206 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1991-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116192217","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
