“…However, we consider different type of data that is time series data of faults. In a different work by Lazarova-Molnar et al 7 they consider timed data for components with more than two states and provide a complete solution to calculate reliability measures from observational data.…”

“…First, time series data recorded from n systems/machines are combined and converted to a truth table with time steps. Then, we follow our previous work, 7,22 and apply DDFTA algorithm that comprises of two main steps: (1) structure learning, or the qualitative analysis part and (2) quantitative analysis based on the output of the first step. In the structure learning step, we extract the minimal cut sets from the time series data set collected from multiple systems, and then use Boolean algebra to build a fault tree that aims to be mathematically identical to the true fault tree of the system.…”

“…More advanced tools are also used, including deep learning methods [9,38,10,53,77], based on Monte Carlo simulation [46,21] as well as kriging and first-order reliability [48]. Perti nets [17], Fault tree analysis (FTA) [34], and the load duration distribution method (LDD) [47] are also used. Particularly popular are also time series methods, including e.g.…”

“…Rare events and the thereby reached system states are guaranteed to be considered. The method has shown to be applicable for the numerical simulation of stochastic Petri Nets, warranty models and Fault Tree Analysis (FTA) (Lazarova-Molnar et al 2020;Lazarova-Molnar and Horton 2003;Niloofar and Lazarova-Molnar 2021).…”
