The reliability of large systems can be represented by reliability fault trees that contain the failure probabilities for the individual elements in the original network and the logical connectives that describe the interdependence of those probabilities. The PATREC 1 computer code was written to demonstrate the feasibility of using list processing techniques for the resolution of a reliability fault tree by pattern recognition. PATREC 1 was written in PL/1 and is used widely in France. The fault tree is expressed as a linked data structure, oriented, mapped into an end-ordered traverse, and used to retrieve known patterns stored as a linked-tree library. The basic idea of pattern recognition is to prune the fault tree by identifying known patterns, retrieving the corresponding mathematical equation, and evaluating the replacement leaves. This process is repeated until the original tree is reduced to a single leaf - the system reliability.
