英文摘要:
In this paper we discuss an empirical phenomena known as the 20-60-20 rule. It says that if we split the population into three groups, according to some arbitrary benchmark criterion, then this particular ratio implies some sort of balance. From practical point of view, this feature often leads to efficient management or control. We provide a mathematical illustration, justifying the occurrence of this rule in many real world situations. We show that for any population, which could be described using multivariate normal vector, this fixed ratio leads to a global equilibrium state, when dispersion and linear dependance measurement is considered.

中文摘要:
在本文中,我们讨论了一种被称为20-60-20规则的经验现象。它说,如果我们根据任意的基准标准将人口分成三组,那么这个特定的比率意味着某种平衡。从实践的角度来看,这一特性通常会导致有效的管理或控制。我们提供了一个数学说明,证明了这一规则在许多实际情况下的合理性。我们证明,对于任何可以用多元正态向量描述的种群,当考虑色散和线性相关测量时,这个固定比率会导致一个全局平衡状态。
