摘要
为合理评价既有结构构件可靠性,基于博弈论和可拓学理论构建博弈论-可拓学评价模型.首先运用区间数对博弈论赋权计算方法进行改进;分别使用区间层次分析法和熵权法计算指标的主客观权重,通过改进后的博弈论赋权计算方法得到指标的综合权重;利用可拓学对既有结构构件进行可靠性评价.研究结果表明:博弈论-可拓学评价模型能够全面、合理地评价既有结构构件可靠性.
In order to evaluate the reliability of the existing structural members in reason,this paper constructed game theory-extenic evaluation model based on game theory and extenics theory.Firstly,this study improved the game theory empowering calculation method by intervals,and calculated the subjective and objective weights of indicators using interval analytic hierarchy process and entropy method respectively.The comprehensive weight of the indicator was obtained by the improved game theory.Extenics was used to evaluate the reliability of existing structural members.The results indicate that game theory-extenics evaluation model is effective to evaluate the reliability of existing structural members comprehensively and reasonably.
