Abstract

Multi Parameter-Path length method for Resilience (MP-PLMR), has been proposed to determine the resilience of system multi-parameter considerations. It was applied to two engineering situations : (i) Passive catalytic device for hydrogen management in Nuclear Power Plant (NPP) (ii) Engineered systems for hydrogen mitigation in NPP. The method involves normalizations of the system parameters, the time domain and correlation coefficient across the parameters. The path length for the transient was defined using all the parameters and their correlations. The resilience value in the two case studies depended on the number of parameters considered and correlations. System resilience without the consideration of correlation was also estimated. The difference between the correlated and uncorrelated resilience was significant. While there is no established metric against which the calculated values could be compared, these values can be used to define system effectiveness in conjunction with reliability of systems.

弹性多参数路径长度法在工程系统中的应用

多参数路径长度弹性法(MP-PLMR)，已被提出，以确定弹性系统的多参数考虑。应用于两种工程情况:(1)核电厂氢管理的被动催化装置(2)核电厂氢缓解工程系统。该方法涉及系统参数、时域和参数间相关系数的归一化。利用所有参数及其相关性来定义瞬态的路径长度。两个案例研究中的弹性值取决于所考虑的参数数量和相关性。对不考虑相关性的系统弹性进行了估计。相关弹性与不相关弹性差异显著。虽然没有既定的度量来比较计算值，但是这些值可以用来定义系统的有效性以及系统的可靠性。
