摘　　要：为了提高配合比优化速度,用最小二乘法思想把矿料组成设计问题转化为带有约束非线性规划数学模型,并用内部罚函数法将其转化为无约束线性规划的问题,采用迭代法中的最速下降法进行求解,得出最佳矿料比例。To improve the coordination ratio optimization speed, the mathematical model of the mineral composition design problem with constrained nonlinear programming is converted by the idea of least squares,and the internal penalty function method is used to transform it into a problem of unconstrained linear programming, and the fastest descent method in the iterative method is used to solve and the optimal ore proportion is obtained.

关 键 词：最小二乘法 非线性规划 最速下降法 CAVF法 路用性能
