Abstract
This paper attempts to develop an expert system for assessing the reliability of existing structures. Similar to the usual expert system, this system consists of interpreter, rule-base and working memory. However, this system has such a remarkable feature that it includes a fuzzy manipulation system which can treat fuzzy sets in the process of data handling, rule representation and inference procedure. Using this system, it is possible to deal with various kinds of uncertainties and ambiguities involved inherently in the data, rules and inference process in a unified and simple manner. An illustrative example is presented to demonstrate the applicability of the system developed herein.
