Abstract :
RVSM (reduced vertical minimum separation) means reducing vertical minimum separation from 2000 feet to 1000 feet between FL290 (flight level) and FL410 (inclusive). However, it must be sure that it is safe to implement RVSM. The internationally accepted collision risk model-Reich model with a target level of safety is used to determine whether it is safe or not to implement RVSM. RVSM airspace includes discrete-event model and continuous-time model, while both the discrete-event model and continuous-time model are unable to simulate the airspace system accurately, Multi-agent based simulation can merge different types of simulation models into a combined simulation model. Therefore, this paper used multi-agent based simulation to establish several agent models and an environment model of Chinese RVSM airspace firstly, then through adopting the proper timing mechanisms, safety of Chinese RVSM airspace was estimated based on the internationally accepted collision risk model.
