MULTINARY SYSTEMS AND RELIABILITY MODELS FROM COHERENCE TO SOME KIND OF NON-COHERENCE
After a general viewpoint on reliability models for multinary systems, coherence generalizations are examined. In terms of structure functions, binary coherent systems can be fully characterized in terms of minimal path (cut) sets and life functions. These treatments are briefly reviewed and generalized for the multinary case. The (N+1)-level broad sense coherent systems are first considered. Various fundamental notions are introduced in terms of structure functions. Binary decompositions are used for characterizing broad sense coherence in terms of sets; this leads to some fundamental relations for multinary systems analysis. Binary-type coherence, homogeneous coherence and the various types of strict sense coherence are reviewed and characterized. Life functions lead to some model useful for reliability calculations whereas the results first obtained in terms of (N+1) levels systems can be generalized for the whole multinary case. Methods for determining, in an "exact" or "approximated" way, reliability characteristics of multinary coherent systems are studied from both of the fundamental models of reliability, then possible. Furthermore, some kind of non-coherent multinary system is suggested.
