摘　　要：本文针对于混合整数非线性规划问题的全局最优化的难点，提出了一种全新的全局最优化方法一函数逼近的割平面全局最优化技术：通过对优化变量的函数构建和逼近，根据目标函数代表的性能进行广义的平面切割，反复交替的操作缩小全局最优解的区间；同时，基于这种方法分析和提出了优化变量的序列生成方法。In this paper, a new global optimization method is brought forward aiming at the difficult of mixed-integer nonlinear programming problem in global optimization research function approaching and cutting plane for global optimization method. Based on the objective function, Construct a new function and approximate the objective function through the optimization variables. cut the plane depending on the target function representative performance. Iterative operation, reduce the space of global optimization solution; at the same time, analyse this method and bring forward the method of the sequence of optimization variables.
