FTANS ߝ A Computer Program for Probabilistic Analysis of Non-Coherent Structures

A code for probabilistic analysis of non-coherent structures is described. An input to the program is a dual fault tree description and probabilities of primary events, an output of the code is a complete nonredundant set of prime implicant sets and probability of the top event. The main features of the code are simple use, good speed, and low computer memory requirements based on the use of environmental assembler routines and on the description of the events by one byte words.
