Rescue trips are time-sensitive and always generated after an earthquake disaster. However, the earthquake destructions to the network might cause costly detour travel time from supply units to demand areas. To make the network structure more reliable, network design strategies are presented in this paper. The concept is to designate a time-efficient structure of shortest path forest among supply-demand pairs. To bring network survivability for the demand group, the bridge routes are prepared beforehand to avert disconnections to the supply units. To enhance reliable supply resources, mutual assistance network is embedded to connect each territory to another supply unit. The software developed for different network patterns to implement this concept is proposed. Edge-set representation of undirected graph data files is applicable for the network design. Supply units and demand areas can be directly assigned on the network map. And indices of average travel cost, detour cost, mutual assistance cost, and network cost are calculated and provided for the network planners' reference.
