to calculate the weight coefficients of the combination model firstly the lagrangian multiplier method is applied to object function and equality constrains.
在组合模型的权重系数求解中,首先对目标函数和等式约束使用拉格朗日乘子法来求解权重系数。
with the equivalent problem, the lagrangian multiplier method is finally employed to obtain the optimum solution in an analytical form to the original problem.
