A Cost-Efficiency Equilibrium Problem of Regional Single Emergency Resource Guarantee with Multi-objective Programming

In the background of regional emergency resource guarantee engineering to respond to earthquake disasters, a multi-objective model of cost-efficiency equilibrium problem is built to guarantee the supply of single emergency resource in an area, combined with qualitative analysis of key factors affecting the resource layout. The model quantifies constitutional indexes about emergency resource guarantee cost and rescue efficiency. With robust optimization ideas, the model is transformed to single-objective programming model according to three decision criteria, and solved with branch-and-bound algorithm by Lingo software. Finally, a numerical example is illustrated to verify the model and decision criteria.
