基于改进层次分析法的动力定位系统综合评价

Improved analytic hierarchy process based design for evaluation system of dynamic positioning systems

文章从分析动力定位系统的体系结构入手建立系统评价的指标体系,即将测量效能、控制效能和推力效能3方面作为动力定位系统效能的第一层准则;位置参考系统可靠性、数据处理与融合能力、原动机功率转化能力等作为第二准则层。文章针对动力定位系统的效能评估工作,采用了改进的层次分析法为评估算法,以某耙吸式挖泥船为研究对象进行评估,最后评估结果与实际运行情况相符,验证了方法的可行性和有效性。

In this paper, an index system for Dynamic Positioning System efficiency is built up by analyzing the architecture of the Dynamic Positioning System,Then build the objective level of the mode ,namely measuring system,control system and thrust system,obtain the criterion level of the competency model which obtain System Reliability,data processing ability,Power transformation capacity and so on.Finally,it applies the improved AHP method to evaluate the capability of Dynamic Positioning System by taking a trailing suction hopper dredger as a research object.The example is illustrated to show the feasibility and practicability of the developed method.
