Structural quantization of vagueness in linguistic expert opinions in an evaluation programme
This paper aims to develop a methodology for the construction of a membership function for linguistic expert opinions in a realistic evaluation problem. It contains a PC-aided procedure of information acquisitions and modelling of data for favour of an evaluator's aid. It assumes that the evaluator need not he knowledgeable in fuzzy mathematics but use common linguistic terms in the making of his expert comments and uses his subjectivity and common reasoning ability (and sincerity) in conversation with the system. For this purpose, a follow-up model is supplemented which assumes existence of a single expert only. (C) 2001 Elsevier Science B.V. All rights reserved.
