Title: A method to federate a discrete event-based logistics simulator and a discrete time step-based traffic microsimulator: a transportation case study (WIP)
Abstract: The primary focus of computer simulation in transportation engineering has been to model individual systems, using individual modeling software packages. However, this limits the ability to explore interactions between multiple disparate transportation systems in a dynamic modeling environment. To address this gap, this study develops and tests a technique to federate two transportation models, each constructed using different simulation software packages: (1) a discrete event-based simulation model of a freight trucking terminal, and (2) a discrete time step-based traffic microscopic simulation model of the network serving the terminal. The federation technique is tested to determine if feedback loops are established dynamically between the models during simultaneous simulation runtime. The findings suggest that this federated simulation technique captures the dynamic interaction of the two systems being modeled. A comparison of the observed versus expected time-based characteristics of the interactions are shown to yield statistically significant correlation.
