Precision of an expert fuzzy model

Abstract

The aim of this paper is to present some difficulties which can be met when a fuzzy model is built with a domain expert help. The paper discusses methods used at succeeding steps of expert modeling process and also presents some of them on a real example. The main concern of the paper is a high quality of a fuzzy expert model which can be easily missed when not all aspects of expert modeling are carefully tackled. Practical experiments presented in the last part of the paper shown that most popular methods used in the process of interviewing an expert are not always appropriate and can be a reason of creating a completely useless expert model. © 2012 Springer-Verlag Berlin Heidelberg.
