NETWORK PERFORMANCE IMPROVEMENT UNDER STOCHASTIC EVENTS WITH LONG-TERM EFFECTS

Natural disasters such as earthquakes and hurricanes can have long-term adverse effects upon networks. This paper examines the problem of improving a transportation network by reinforcing its links to increase their resistance to such incidents. A measure of link performance is presented based on consumers' surplus. This measure is then used to define and solve a network improvement problem. The measure identifies a set of feasible links, which when upgraded to withstand natural destructive incidents, would increase the network reliability significantly. Computational complexities are reduced by introducing an approximate measure of link importance that shows good accuracy compared with exact link importance values, and hence may be used for solving large scale problems. Several example networks that differ in link cost function and topology are used to demonstrate the applicability of the presented approximate method of computed link importance.
