About the Definition of Coherency in Binary System Reliability Analysis

  • A. Amendola

This paper was stimulated by discussions which arose at the last NATO-ASI in Urbino and by Caldarola’s new definition of coherency [1]. Moreover, the development of a procedure, for the analysis of a fault-tree constituted by AND-OR-NOT gates [2], showed the necessity of identifying the possible logic structures of actual physical systems.
