under Time Constraints

Abstract: Network reliability refers to the probability of a successful connection between a source node and a sink node in a network. Network reliability is extremely important since networks have been widely applied to data transmission, telecommunication, and power transmission. A novel network called the time-constrained multi-commodity multistate-flow network (TMMN) is a new extension involving the quickest path problem and the multi-state network which transmits multi-commodities. This work obtains feasible solutions with considerable constraints using a novel simple algorithm and evaluates network reliability when u types of commodities are sent from a source node to a sink node through a TMMN within T units of time. No existing method can evaluate all quick paths (QPs) in a TMMN.
