Computer Codes for System Reliability Analysis

Assigning the correct probabilities to the components, combining these numbers according to system logic and numerically solving the system model, only can be done practically with a computer using the codes that have been developed over the years. 

The PSA Procedures Guide (NUREG/CR-2300) summarizes many of the codes, and the Fault Tree Handbook (NUREG-0492) contains an overview discussion, but these sources do not
