提出了多参数路径长度复原法(MP-PLMR)来确定系统多参数的复原性。它被应用于两种工程情况：(I)核电厂(NPP)氢管理的被动催化装置和(Ii)核电厂氢缓解工程系统。该方法包括对系统参数、时间域和参数间的相关系数进行归一化。使用所有参数及其相关性来定义瞬变的路径长度。两个案例研究中的恢复力价值取决于所考虑的参数数量和相关性。在不考虑相关性的情况下，估计了系统的弹性。相关复原力与非相关复原力的差异显著。虽然没有可与计算值进行比较的既定指标，但这些值可用于定义系统效率和系统的可靠性。
Multi-parameter-path length method for resilience (MP-PLMR) has been proposed to determine the resilience of system multiparameter considerations. It was applied to two engineering situations: (i) Passive catalytic device for hydrogen management in nuclear power plant (NPP) and (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.
