Fuzzy model for analysing implicit factor influence

The article deals with the problem of analysing implicit factor influence. It later reveals a mathematical model for conducting a search for implicit factors within a system which is based on a fuzzy set theory and employs fuzzy binary relations and is put into practice as a combination of web-services posted on http://bi.usue.ru/. The model's capability to identify implicit factors by making use of expert judgements presented in natural language is lastly demonstrated.
