Development and Benchmarking of an Epoch TimeSynchronization Method for Distributed Simulation

摘要

In this work, a new epoch time synchronization approach for distributed simulation federates is proposed.rnThe approach allows federates to advance their local times at full speed to the minimum of the estimatedrnnext epoch event times, which are calculated by a recursive look-ahead function at each federate. Arnclient/server infrastructure is also presented for distributed simulation. The proposed approach andrninfrastructure are demonstrated using a manufacturing supply chain simulation composed of fiverndistributed federates. The experimental results reveal the proposed approach improves supply chainrnsimulation execution time significantly while maintaining complete accuracy as compared with thernconservative synchronization approaches.
