User's manual for MOCUS-BACKFIRE [i.e. MOCUS-BACFIRE] : a computer program for common cause failure analysis

Abstract

This report is the user's manual for MOCUS-BACFIRE, a computer programme for qualitative common cause analysis. The MOCUSBACFIRE package code was developed by coupling the MOCUS code and BACFIRE code. The MOCUS code is a computer programme to generate cut sets of a fault tree. BACFIRE is a computer programme to search among the basic events of a minimal cut set for potential common casuse failures. Both codes are written in FORTRAN IV for the IBM 360/370 computer series. The input data to MOCUS-BACFIRE are the fault tree and common cause susceptibilities. The input and output of the programme are described in detail in this handbook.
