The unified approach of two-phase method and big M method 谈两阶段法与大M法的统一处理方法
In the simplex method of linear programming, there is a big M method ( the penalty factor method) for finding an initial feasible basis. 在线性规划的单纯形法中,为求初始的可行基有著名的大M法,即惩罚因子法。
In view of the big noise and limited handling ability of large expanse of wild value in the existing Data Appraisal Function Weighted Method, this paper proposes a multi-sensor data weighting fusion method which combines the M-estimate and the uncertainty appraisal. 提出M估计与不确定度评定相结合的多传感器数据加权融合方法,克服了现有的数据评价函数加权法中存在的大噪声及成片野值处理能力的局限性。
In this paper, based on pointing out the mistake in, the author improves the fashion of introducing artificial variables in big M method. 本文在指出文献[2]缺点的基础上参考该法优点,对大M法引进人工变量的方式进行了改进,给出了至多引进一个人工变量的求线性规划问题的一种新算法。
Based on the characteristic that the guideway is long ( 3-6m) and straightness error is big ( 0.3mm/ m), and it is very easy to go beyond the range to use conventional methods, so we bring forward the straightness measurement method based vision measurement. 根据课题中发射筒的导轨长(3-6米),直线度误差大(0.3mm/m)的特点,利用传统的准直光管或激光准直法很容易超出量程,提出了基于视觉测量的直线度测量法。
An Analysis of the Consistency of Big M Method and Two-Phase Method 浅析大M法与两阶段法的一致性
The consistency of the Big M Method and Two-Phase Method in idea, auxiliary linear programming problem, initial feasible basis, initial simplex tableau and optimality criterion, etc., is analyzed. 分析了大M法与两阶段法在思想方法、辅助线性规划问题的构造、初始可行基、初始单纯形表、最优性检验和算法步骤等方面的一致性。
