  7. Abstract:
  8. Resiliency is, now, recognized as a vital characteristics of every urban transportation network. This is so, because transportation network is considered as a life-line in disastrous events, such as major earthquakes. In this respect, design of networks may be considered (1) before the incident, (2) after the incident for 72 hours, and (3) from this 72 hours on. From the point of view of (1), design of the network may be considered as strengthening important links under budget constraints to withstand the design incident, in order to be able to function properly (to help the affected people, to evacuate the populated area, etc.).Design of network based on the point of view of (2), the one of concerns in this study, may be designed as a bi-level programming, in the upper-level of which crippled links in the disaster are chosen by the operator to be brought back to the network: this is done by an array of crews stationed at certain locations in the network to help the devastated populated areas in regions. Their movements to save the people in the ruined structures are the tasks followed in the lower-level problem.The problems is formulated and solved by applying it on two test networks, the Sioux Falls, USA, and the Kish Island, Iran. Considerable analyses of sensitivity are also done and the results are presented
