Robustness Verification of Railway Level Crossing Control System by Formal Method

Logical consistency verification of state sensing in safety‐critical decision: A case study of train routing selection

“…Wang et al. [11] detected a flaw in the current specifications of the level crossing system by the RODIN modelling and verification platform, and revealed that defects might still exist in the verified model as long as the safety analysis is insufficient before the system modelling. In recent years in the field of the information disciplines, such as Gomes et al.…”

“…In the domain of railways, for example, Mekki et al [9] suggested a new automatic protection system of the level crossing to prevent two risky scenarios, and validate the new architecture with model checking techniques; Snook et al [10] proposed two alternative approaches to using scenarios during formal modelling, illustrated the two approaches on the 'Tokeneer' secure enclave example and the ERTMS/ETCS Hybrid Level 3 specification for railway controls based on the Cucumber framework, Event-B modelling language, and toolset. Wang et al [11] detected a flaw in the current specifications of the level crossing system by the RODIN modelling and verification platform, and revealed that defects might still exist in the verified model as long as the safety analysis is insufficient before the system modelling. In recent years in the field of the information disciplines, such as Gomes et al [12] developed a modular and reusable framework in the Isabelle/HOL interactive proof assistant for verifying strong eventual consistency in distributed systems; Hammal et al [13] proposed a formal method for compatibility and consistency checking of WS-BPEL orchestrations of composite OWL-S Web services; Zhao et al [14] proposed and verified a new consistency protocol to make write-dominant applications as fast as possible and as consistent as needed.…”
