GSM-R (Global System for Mobile Communications-Rail) is employed as the main channel to transfer safety data in high speed rail control system. Its reliability directly affects train safety. In the analysis of two different GSM-R redundant networks, we use the Alta Rica language and Markov Chain in modeling. Combined with related data, system reliability(More)
Fault Tree Analysis (FTA) is a classic method in reliability and safety engineering. With the increase of system scale and complexity, the amount of work is heavily loaded. Thus the computer aided FTA method is important for related analysis. Existing computer aided FTA analysis methods invariably confront combinatorial problems which are computationally(More)
The messages sending process, especially caused by the monolithic function correlations defined in the application layer of Open Systems Interconnection (OSI) field bus system used in building and home automation, results in a message peak in the Data Link Layer (DLL), which has been seen as the new feature challenging the Quality of Service (QoS) of the(More)
