进行医院工作质量的多指标综合评价几乎无一例外地要涉及到指标值的标准化,以消除各评价指标量纲不同的影响,达到指标间的可加性或可乘性.目前指标值的标准化多使用线性方法.而事实上医院工作质量的指标值所反映的实际水平却极少为线性变化,故标准化值作为刻划原指标值实际水平的一个指标,采用原指标值的线性变换则具有明显的不合理性.本文引入了非线性变化的思想并提出一种幂转换的非线性标准化方法,结合一个实例运用非线性标准化方法进行了综合评价.
Comprehensive evaluation of multi-criteria for hospital quality of work almost without exception involves the standardization of index values to eliminate the effects of different dimensions of the evaluation indicators and to achieve inter-index additiveness or multiplicity. The current standardization of index values The linear method is often used. In fact, the actual level reflected by the index value of hospital work quality is rarely a linear change. Therefore, the standardized value is used as an indicator of the actual level of the original index value, and the linear transformation using the original index value has Obvious irrationality. This paper introduces the idea of nonlinear change and proposes a power conversion non-linear standardization method, combined with an example using a nonlinear standardization method for comprehensive evaluation.
