Design and Implementation of Real-Time DEVS Event Scheduling Algorithm

This paper focuses on the concept and description specification of Real-Time Discrete Event System(RT-DEVS) simulation, and proposes a frame-based real-time event scheduling strategy and multi-thread real-time event scheduling algorithm in RT-DEVS simulation. Based on the JMASE platform discrete event scheduling engine, the real-time event scheduling module of discrete event system simulation is designed to increase the function of real-time event scheduling service, and the implementation method and steps of real-time synchronization behavior are described in detail. Finally, the function and real-time performance of real-time event scheduling module are tested through the simulation experiment. The results show that the RT-DEVS simulation event scheduling algorithm implemented in this paper can meet the requirements of real-time simulation.
