摘要
提出基于模糊决策及集对分析的船舶动力装置可靠性检测分析方法,假设船舶动力装置中共存在若干传感器对动力转置的故障进行检测,确定隶属度函数,给出隶属度函数的详细数值。通过隶属度矩阵对所有传感器中各决策判断的可信度进行描述,依据最大隶属原则、阈值原则等完成模糊判断。在增强综合检测精度的前提下,采用最大隶属原则和阈值原则相结合的方法完成故障检测。将影响船舶动力装置的可靠性因素作为评价指标,评价指标及评价标准作为2个集合,并构成一个集对,在此基础上对船舶动力装置的可靠性进行检测分析。仿真实验结果表明,改进方法具有很高的检测精度。
Put forward based on fuzzy decision and set pair analysis of a ship power equipment reliability testing method,assuming that ship power plant of the communist party of China there are several sensors to detect the failure of dynamic transpose,determine membership functions,detailed numerical membership functions are given. Through the membership degree matrix of all sensors in the decision to judge the credibility of the description. Based on the principles of maximum membership,etc,the principle of threshold fuzzy judgment. On the premise of enhancing comprehensive precision,using the principle of maximum membership principle and threshold value method of combining the fault detection. Will affect the reliability of the power plant of ship factors as evaluation index,evaluation index and evaluation standards as two collections,and form a set of,on the basis of the reliability testing analysis of the ship power equipment. The simulation experimental results show that the improved method is of high precision.
