A hierarchical method for the reduction of temporal expressions in Pandora

Walker, Martin; Papadopoulos, Yiannis

Abstract

Fault Tree Analysis (FTA) is a popular safety analysis technique used to determine the logical combination of events needed to cause a particular system failure. However, FTA is purely combinatorial and cannot analyse the effects of sequences of events. A recent technique named Pandora was proposed as one method of overcoming this limitation by introducing a temporal logic to fault trees, but the resulting expressions are generally more complex. In this paper, we propose a hierarchical method for reducing these expressions to simpler logical equivalents, which can be more easily understood and thus provide a better view of the system failure behaviour.
