摘要
将有序加权算子(OWA)及其相关算子推广到时序数据集结的方法中,提出了时序加权平均(TOWA)算子和时序几何平均(TOWGA)算子两种新的算子,并应用于动态综合评价方法中.同时介绍了TOWA和TOWGA算子加权向量(即时间权向量)的确定方法.最后,将该方法用于评价西部12省市在国家实施"西部大开发"战略后6年的宏观经济发展状况,结论验证了方法的有效性.
Decreasing dimensions is key of dynamic comprehensive evaluation problems, which turns multidimensional 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 twlce-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.
