摘要
通过对动力定位系统体系结构的分析,确立动力定位系统RAM评估指标的层次结构,即系统可靠性、系统可用性、系统可维护性。文章针对动力定位系统RAM的评估工作,采用AHP法确定评估指标体系各指标权重,建立了模糊综合评判模型,对系统的RAM进行量化,并对最终可能出现的不同评估结论进行分析与选择。最后以某耙吸式挖泥船为研究对象,验证了该方法的可行性和有效性。
In this paper,by analyzing the architecture of the Dynamic Positioning Systems,first,an index system for the RAM of Dynamic Positioning Systems is built up,namely Reliability,Availability and Maintainability. Then using the AHP method to confirm the weight of the index,a fuzzy-level evaluation method is established for evaluation of the RAM of Dynamic Positioning Systems. After that has analysis and made a choice according to different evaluation conclusion might appear. Finally,taking a key a trailing suction hopper dredger as research object,the feasibility and effectiveness of the method are verified.
