Research on an expert system for TRIZ Method applying
Abstract
TRIZ method is a powerful creative technique, used in the most diverse and competitive fields of engineering, and, among others, in value analysis / engineering. Psychological creativity tools, including brainstorming and related methods, have the disadvantage that they have unpredictable and unrepeatable results. Unlike these TRIZ provides repeatability, predictability, reliability and algorithmic approach. One of the fundamental concepts of TRIZ is that contradiction which must be removed from a technical system. It was found that there are 39 standard technical features that could lead to contradictions in the technical system analysis and 40 inventive principles that can resolve generated conflicts creatively. For this a method was developed to correlate the conflicts with inventive principles known as the “contradictions matrix”. On the other hand, a problem in a particular area, it is a good candidate for expert system technology if it meets several criteria. One of the most important activities that precede construction of an expert system is knowledge representation, among the most popular models of knowledge representation being decision tables. The contradictions matrix can be transformed in decision tables with standard structure. An expert system for TRIZ method should, based on the 39 parameters that may in conflict, choose the inventive principles from contradictions matrix and then for each inventive principle chosen provide examples and afferent details and other related items resulting from experience.
