业务中心“分类矩阵式考核法”

设计中心是某电力行业经研院(以下简称“经研院”)核心业务单位之一,是经研院落实新时代战略发展要求的重要支撑。随着上级单位要求提升、业务定位发展,原有的绩效管理模式在运行中反馈出一些问题,影响员工活力动力的激发。按照建立“导向清晰、评价科学、激励有效的一流绩效管理体系”的导向,经研院基于业务中心目标实现,结合业务特点和业务流程全过程管理,重新设计符合设计中心特点的分类矩阵式考核法,进行分类考核,提升考核激励的有效性,促进公司高质量发展。

Effect of Heteroscedastic Variance Covariance Matrices on Two Groups Linear Classification Techniques

The authors investigate the comparative classification performance of the two groups linear classification techniques. They compared the Fisher linear classification analysis, its robust version based on the minimum covariance determinant with the Filter linear classification rule and the linear combination linear classification technique. These procedures are investigated using laboratory reared aedes albopictus mosquito data set and simulated data set generated based on heteroscedastic covariance matrices with various proportion of contamination. The evaluation procedure is based on the effect of contamination on the mean probabilities of correct classification obtain for each technique. The comparative analysis revealed that the robust Fisher linear classification rule and the linear combination linear classification rule are robust and comparable than the other procedures.
