Thirdly, the model solves the problem that multiple Nash equilibrium occurs in the game results by risk-dominant mechanism, and then the optimal solution could be obtained.

第三，模型通过使用风险占优机制来解决博弈结果存在多重纳什均衡的问题，从而选择出最佳应急物资调度方案；

For the more than one crossfeed dominant surfaces, the one whose safety index is least is defined as the crossfeed surface based on limit equilibrium theory.

对于多个互馈优势面，采用极限平衡理论计算各个面的抗滑稳定安全系数，定义安全系数最小的面为互馈面。
