This paper presents a graph-based representation of success trees to evaluate the reliability of an embedded system. First, a success tree is constructed by deriving a characteristic function from a graph-based system model automatically. The constructed success tree is then translated to a graph (called a success graph) which supports both cyclic and acyclic data dependencies in applications to be...
Trust is a crucial basis for interactions among parties in social networks. This paper presents a binary decision diagrams-based algorithm for trust sensitivity analysis in social networks. Based on trust scores of direct links, the trust sensitivity analysis can help identify which direct link (s) in the social network contributes the most to a trust relationship between two particular parties who...
Two different methods of flow analysis are discussed, one a significant generalization of the other. It is shown that the two methods have significantly different intrinsic computational complexities. As an outgrowth of our observations it is shown that a feature of the programming language used by Dijkstra in A Discipline of Programming makes it unsuitable for compile-time type checking, thus suggesting...
