A Geotechnical KBS Using Fuzzy Logic
This paper presents an application of knowledge-based systems techniques involving a fuzzy logic framework in the domain of geotechnical engineering. Knowledge-based systems (KBS) are emerging as a powerful means of dealing with the ill-structured problems encountered in many engineering and medical applications. Stefik et al. [Stefik 82] state that expert systems are problem-solving programs that solve substantial problems generally conceded as being difficult and requiring expertise. They are called knowledge-based because their performance depends critically on the encoding of facts and heuristics (rules of thumb) used by experts. In a KBS the knowledge pertaining to the domain are encoded in the system in an explicit manner; this knowledge can be examined and modified, if necessary.
