Abstract

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