A Method and Application of Dynamic Comprehensive Evaluation
一种动态综合评价方法及应用

Decreasing dimensions is key of dynamic comprehensive evaluation problems,which turns multi-dimensional time series to 2-dimensional data.This paper extends the ordered weighted averaging(OWA) operator to aggregating data in dynamic comprehensive evaluation problems and presents two new operator(time ordered weighted averaging(TOWA) operator and time ordered weighted geometric averaging(TOWGA) operator).Then,two new methods are presented,which are twice-weighted evaluation and prefix comprehensive evaluation.And the paper introduces mathematical programming model in order to solve TOWA and TOWGA weights(time weights).Finally,a numerical example was given to illustrate the effectiveness of the proposed method.
