ASTRA 3.0: Test Case Report

Abstract

In the context of activities related to the application of system analysis to safety and security of critical installations a new logical and probabilistic fault tree analysis procedure was developed and implemented in the software package ASTRA, version 3.0. This report contains the results of the logical and probabilistic analysis for a limited, but significant, subset of test cases considered during the test campaign performed at the JRC. Most of the described test cases come from the open literature, for which results are available to the reader. For more complex test cases ASTRA 3.0 was compared with other available tools, such as ASTRA 2.0 and XS-MKA, a Markovian analysis package. The experience gained with the testing activity also allowed the identification of a set of recommendations for future improvements.
