In chapter 3, the group decision - making is applied in the safety evaluation, and the credit degree is put forward to considering the experts " appraisal level. the principle of set - valued statistics and the fuzzy gravity center based decision theory are put into a new method, and are applied in the uncertain type of ahp. hence, the weights of evaluation indices that reflect the experts " level are gained. this measure, which reflects the objective of the evaluation process and the subjective of the experts, can concentrate various opinions and lower the deviation of the evaluation process. a new method of calculating weights and variable weight is presented in the safety evaluation, and it is discussed that how the method of variable weight is applied in several evaluation methods
在原有的集值統計原理的基礎上，引入對專家評判水平的評判? ?專家的權重，形成加權的集值統計原理，並與重心決策理論相結合，計算出考慮了專家水平差異的橋梁安全性評價指標的權重。這樣處理反映了評價的客觀性和參評人員的主觀性，能很方便地集中多種不同意見，減少了評價過程中的隨機誤差。在橋梁安全性評價中，為了反映橋梁狀態發展的不均衡性，使評價過程更趨于合理，評價結果更可靠，將變權原理應用於橋梁安全性評價，探討變權原理在多種評價方法中的運用。
