Research on consistency measurement and weight estimation approach of hybrid uncertain comparison matrix

The consistency measurement and weight estimation approach of the hybrid uncertain comparison matrix in the analytic hierarchy process （AHP） are studied. First, the decision-making satisfaction membership function is defined based on the decision making＇s allowable error. Then, the weight model based on the maximal satisfactory consistency idea is suggested, and the consistency index is put forward. Moreover, the weight distributing value model is developed to solve the decision making misleading problem since the multioptimization solutions in the former model. Finally, the weights are ranked based on the possibility degree approach to obtain the ultimate order.     

文化观转型与“象思维”之失

20世纪初以降，自从教育制度西化之后，在开启科学思维理性之窗时，却关闭了自己“象思维”的悟性之窗，致使中国学人陷入失去主体话语境地。后来几代学人，由于只有单一科学思维理性，以至于不能真正进入和领会中国传统经典。中西思维方式不同，源于语言不同。“象思维”作为前语言前逻辑的思维，是最具本原性和原刨性的思维。在“轴心时期”，西方在“象思维”基础上产生出理性的逻辑的概念思维，并逐渐构成西方文化主流的思维方式。而中国的“象思维”则经过儒、道、佛三家而推向高级形态，构成中国文化主流的思维方式。崇尚不同最高思想观念（非实体与实体）的中西思维方式，各有不同的功能和价值，但都非万能。两种思维方式相互不能取代，而只有经过会通，才能推进各自文化的创新与发展。

排序向量的三个近似解系研究

AHP排序向量的"近似解法"至少可导出三个解系:K阶行平均法解系、K阶规范列平均法解系和K阶列平均倒数法解系.均在给定的比例判断矩阵的前提下,进行归一化处理,获得各自的排序向量.而当判断矩阵不一致时,其排序向量的结果也存在着差异.同时还存在继续研究的"真序"向量和AHP排序向量的其它近似解法.

Exponential smoothing: Behavior of the ex-post sum of squares near 0 and 1

When using simple exponential smoothing on a given time series the nature of the relationship between the optimal smoothing constant and the autocorrelation structure of the series remains an unresolved question. Although numerical search routines can easily be used to find optimal values of the smoothing constant, they offer little insight into the nature of the relationship between the estimated smoothing constant and the structure of the underlying time series. We suggest that renewed investigations of the ex-post sum of squares function may prove helpful in this pursuit. Results are presented that illustrate how the optimal smoothing constant depends upon the value used to initialize the smoothing and upon the sample autocorrelation coefficients of the observed series. These results are based on a new formula for the derivative of the ex-post sum of squares function. In particular, the derivative is examined near 0 and 1, where great simplifications occur in its form, thereby facilitating investigations near these points. A necessary and sufficient condition is stated for when the ex-post sum of squares must have a positive derivative at 0 and the autocorrelation coefficients of the differenced series are shown to affect the sign of the derivative near 1. Based on these results, a general algorithm is presented as an alternative to grid search routines for minimizing the ex-post sum of squares.
