The report describes the theoretical background of the method implemented in ASTRA-SAM, the new module of the ASTRA tool-set, developed to perform sensitivity analysis of complex systems. The sensitivity analysis technique, applied on the results of a fault tree analysis, frequently represents a suitable and powerful tool to improve a complex system design from both the safety and availability viewpoints.

The new aspects of ASTRA-SAM, with respect to other analysis tools, concern essentiality the possibility to work on all systems fault trees concurrently and to apply, besides the modification of the reliability parameters, the redundancy concept. Other redundant configurations can be added depending on the user needs. .
