PL-MOD; fault tree analysis by modularization. [IBM370,303x; PL/I]

Technical Report ·
OSTI ID:6228453
PL-MOD performs an analysis of operating systems modeled by means of fault trees using modularization techniques. The program was developed to perform the modularization and evaluation of the modular occurrence probabilities and Vesely-Fussell importance measures for analysis of nuclear reactor safety system fault trees efficiently. It is capable of modularizing fault trees containing replicated components and replicated modular gates and can handle mutually exclusive inputs and explicit higher order symmetric (k-out-of-n) gates.IBM370,303x; PL/I; OS/VS1 (IBM370/168) and OS/MVT (IBM3033); 200K bytes of memory are required for execution.
