Abstract

Summary & Conclusions -Much research has been done on computing connectivity-probability in probabilistic networks. More recently, the area has been expanded to other performance measures, such as maxflow & distance. These problems are, in general, NP-hard. Therefore efficiently computable, and accurate, lower & upper bounds are sought. This paper presents: 1) distance renormalization which generalizes the reliability renormalization algorithm of Harms & Colbourn for bounding probabilistic distances in bi-directional probabilistic weighted networks; 2) a mechanism based on non-planar duality for using this algorithm to bound probabilistic maxflow and mean maxflow. The results obtained via distance renormalization compare favorably with other current techniques for our suite of test cases.
