最优综合评价模型的原理

Principle of Optimal Synthetical Appraise Model

最优综合评价模型是充分利用全部数据当中所包含的信息,把表征每一年技术水平的多指标数据(x_1,x_2,…,x_3)构成一个向量,给向量空间定又一种距离,用距离的大小来表征技术进步的程度,实际上是找到一种直观、简单、易行的映射把向量变为标量,即把被评价单位的技术水平的多指标的数据变成一个数,以便于进行比较。

If technology advance index gain observational guantitative date, the technological advancde level of every unit which be appraised can be indicatde by distand magnitude, ie, weight coefficients is determimted by mecms of nonlinear programming model. This paper strictly gives algebraic proof to principle and puts foward opinion to optimal synthetical appraise model.
