考慮評(píng)價(jià)信息滿意度的群體信息集結(jié)方法研究

摘要： 信息集結(jié)方法是群體評(píng)價(jià)的重要研究?jī)?nèi)容,針對(duì)該問(wèn)題本文對(duì)評(píng)價(jià)信息滿意度進(jìn)行測(cè)度,并基于此對(duì)群體信息的集結(jié)方法展開(kāi)研究。該方法根據(jù)指標(biāo)信息的變化賦予評(píng)價(jià)者不同的權(quán)重,以改變現(xiàn)有研究中評(píng)價(jià)者權(quán)重大多固定不變的做法,旨在使群體信息集結(jié)的結(jié)果更加公正和準(zhǔn)確。首先對(duì)問(wèn)題進(jìn)行界定并給出評(píng)價(jià)信息滿意度的定義;然后分別給出先驗(yàn)信息滿意度和評(píng)價(jià)過(guò)程中的信息滿意度的確定方法,利用先驗(yàn)信息滿意度確定各評(píng)價(jià)者的初始權(quán)重,并利用評(píng)價(jià)過(guò)程中的信息滿意度對(duì)其修正,從而得到各評(píng)價(jià)者的權(quán)重矩陣。最后,按照各評(píng)價(jià)者的評(píng)價(jià)信息滿意度對(duì)群體評(píng)價(jià)信息進(jìn)行集結(jié)。
Information aggregation method is an important research in group evaluation. This paper proposes a method to determine the satisfaction degree of group evaluation information,and further researches a group information aggregation method. In order to further improve the fairness and accuracy,a different weight instead of a fixed one is placed on each index from the same expert in this method. Firstly,the evaluation situation and question are developed,and the satisfaction degree of the evaluation information is defined. Secondly,the methods to determine the satisfaction degree of priori information and the one of current information are presented respectively. The former is used to determine initial weights of experts,and the latter is used to modify those weights. A weight matrix of every expert can be determined in this process. Finally,the final aggregation result of group information is obtained by using these weight matrixes.
