摘要
针对纯定性的SDG模型在复杂系统中建模难度大、分辨率低、可能产生信息爆炸的问题,提出一种结合层次分析法的结构递阶层次,划分故障并建立层次SDG图的方法。在实际应用中结合密相干塔烟气脱硫系统,建立了层次SDG分析,提高了诊断速度。
The fault diagnosis model based on common signed directed graph （SDG） is difficult to built, computationally expensive and with poor resolution to complex system. To solve the problem, an analytic hierarchy process （AHP）-SDG method based on hierarchy structure is proposed and implemented in dense-flow flue gas desulphurization （FGD） system. The application shows that it is efficient.
