基于模糊层次分析法的船闸人字门提升方案评价

Lifting Scheme Evaluation of Chevron Gate of Ship Lock Based on Fuzzy Analytic Hierarchy Process

针对在多方案评价中层次分析法不宜求取各方案权重值的问题,以三峡船闸人字门提升方案为例,提出了一种基于层次分析法和模糊理论的多方案综合评价方法,建立了船闸人字门提升方案评价模型,并对比评价了三种船闸人字门提升方案,最终选出跨闸室简支梁提升方案为最优方案,表明该方法和评价模型合理、有效。

The analytic hierarchy process （AHP） method is not fit for obtaining the weight value of each plan in multi-plan evaluation problems. Taking lifting scheme of chevron gate of three gorges lock for an example, a multi-plan compositive evaluation method is proposed based on AHP and fuzzy theory. And then, the evaluation model of lifting scheme of chevron gate of ship lock is established and three kinds of schemes are compared. Finally, the lifting scheme of spanning lock chamber simply supported beam is selected as the optimum scheme. It shows that the scheme and evaluation model is reasonable and effective.
