Johanyák Zsolt Csaba The purpose of the Design Failure Mode and Effect A nalysis is to detect and avoid the potential failur es that may occur at a given part in the possibly earliest stag e of the quality loop. The procedure itself needs a large amount of time and material support, therefore the practical application of it is really paying only when applie d to very expensive components or to mass production. A way to make larger the field of application of th is method with increased efficiency is using comput er aiding. This enables a quick and intelligent reuse of the knowle dge expressed in previous examinations. This paper presents the model of a case based reasoning knowledge-based sys tem. Here the stored FMEAs represent different case s. In the case of a new project the system searches for simil ar cases in its database and adapts the knowledge t o th present situation.
