“…This is the probability that a pair of nodes in a network remains connected-i.e., there continues to exist a connected path between themwhen one or more links in the network have been cut. Bell and Iida (1997) provided an analytical procedure for assessing connectivity reliability, and a summary of the procedure is given by Iida (1999). Subsequent research was directed at degraded networks, usually urban road networks subject to traffic congestion, in which the network remained physically intact but the performance of one or more links could be so severely affected by congestion that their use by traffic is curtailed.…”

This paper describes the development of a method for strategic assessment of vulnerability in road networks. Our vulnerability analysis considers the socio-economic impacts of network degradation, on the basis of changes in the levels of accessibility provided by the degraded network. A number of standard indices of accessibility are considered, including generalised travel cost, the Hansen integral accessibility index, and the ARIA index used in Australia to assess levels of remoteness in rural areas. Simple case studies of a national strategic road network and a regional road network are used to illustrate both the general approach and specific implementations.

“…2.1.4. Reliability of routes by using a graph theoretical-matrix permanent approach Nowadays, road networks with high reliability are needed to ensure drivers' safety in uctuations of tra c ow and avoidance of unforeseen delays caused by network disruptions [45]. In this study, reliability is de ned based on \graph theoretical-matrix permanentdecision making" as concepts of multi-criteria decision making, which results in determination of the best route with maximum reliability.…”

Abstract. In the event of natural disasters, relief distribution is the most challenging problem in emergency transportation. What is important in response to disaster is victims' relief in disaster areas with the quick distribution of vital commodity. In this regard, damage to infrastructure (e.g., roads) can make trouble in designing a distribution network. Therefore, this paper considers a problem using a three-stage approach. In the rst stage, pre-processing of model inputs is done through an Arti cial Neural Fuzzy Inference System (ANFIS) followed by investigating the safest route for each cluster using decision-making techniques and graph theory. In the second stage, a heterogeneous multi-depot multimode vehicle routing problem is formulated for minimizing the transportation time and maximizing the reliability. Finally, since the routing problem is NP-hard, 2 multi-objective meta-heuristic algorithms, namely, Non-dominated Sorting Genetic Algorithm (NSGA-II) and Multi-Objective Fire y Algorithm (MOFA), are proposed to obtain the optimal solution and their performances are compared through a set of randomly generated test problems. The results show that for this routing problem, the MOFF gives better solutions than NSGA-II does, and it performs well in terms of accuracy and solution time.
