“…At the same time, the model checking method also faces the challenge of state-space combination explosion. As a model checking technology, timed automata are often used in the fields of protocol verification (Li, 2014) and system behaviour stability analysis (Shengxin et al, 2017). In recent years, model checking tools for timed automata, such as UPPAAL (David et al, 2015), have been able to detect large-scale systems by optimizing model checking analysis, which produces good performance in the modelling of the medical monitoring system (Wetselaar et al, 2020), vehicle network system (Guo et al, 2019), system linkage control (Meng et al, 2021) and so on.…”
