PROBABILISTIC DEPENDABILITY ANALYSIS OF ADAPTIVE FUNCTIONS: A FAULT-TREE BASED APPROACH AND ITS APPLICATIONS IN TRANSPORTATION

Abstract

In this paper, a new method is proposed as an extension of the classic fault-tree analysis for the treatment of functionally re-configurable logic. Such logic may change its operation if a failure has occurred and been detected. Since this logic can distinguish between the detected failure and the undetected failure, these must be considered in the fault-tree structure. Closed formulas are applied to ensure efficient algorithm for the analysis. The paper summarizes that way which enables the treatment of re-configuration, and analyzes the limitations of the described methods.
