Abstract

In this paper potential causes that lead to a failure are investigated through a digraph analysis utilizing graph theory tools and pseudo boolean expressions. A generic scenario of a multi-layered scheme for fault assessment for a UAV application, illustrates the proposed methodology. The resulting solution is obtained by the use of shortest path algorithms due to the means the problem is posed and its similarity to routing problems. In addition mathematical formulation and its relevance is also addressed.
