基于改进AHP和熵权法的预制节段梁生产运输方案研究

摘要

针对桥梁的节段梁生产运输方案,分析了近些年已建、在建的具有代表性的桥梁工程节段梁生产运输方案的制约因素,提出了基于改进层次分析法(AHP)和熵权法的节段梁运输方案分析方法.该方法通过定量、客观和可信的分析结果,克服了传统测评中各指标权重确定方法的局限性,做到静态赋权与动态赋权相结合,为建筑单位制定正确、合理和具有高效生产效率的节段梁运输方案提供了重要参考.分析结果表明:对于本文案例中桥梁,方案三和方案二综合指数分别为0.6986和0.6901,在所有方案中排序靠前,而方案一综合指数为0.4140,排序第6,为不宜采用方案.%The festival for bridge precise production transportation scheme,and analyses the already built in recent years,the construction is representative of the bridge engineering festival transportation plan the restriction of the precise production factors,put forward the improvement based on the analytic hierarchy process (AHP) and entropy weight method section of precise plan analysis method.This method through the quantitative,objective and reliable analysis results,overcome traditional evaluation method of determining the weights of the indexes in the limitation of the static and dynamic empowerment to empowerment,combined with construction unit to make correct,reasonable and efficient production efficiency of the quarter with precise plan provides important reference.The analysis results show that:for this paper cases Bridges,scheme sanwa scheme ii composite index were 0.6986 and 0.6901,in all scheme sort in front,and plan a composite index is 0.4140,sort,6 for unfavorable use scheme.
