Military deployment planners and analysts must consider the constraints, options, and available infrastructure of a network of installations and ports, from the beginning of the transportation system in the United States to the end of the deployment in the host country. Argonne National Laboratory developed a suite of models that simulate and visualize these deployments. There are discrete event simulations (the Enhanced Logistics Intra-theater Support Tool, the Transportation System Capability model, and the Port Simulation model) as well as several data editing and visualization tools. This paper presents the models, and discusses how they interact and leverage their shared data and technologies, to facilitate deployment analysis.
Visualization techniques for simulations are often limited to statistical reports, graphs, and charts, but simulations can be enhanced through the use of animation. A spatio-temporal animation allows a viewer to observe a simulation operate, rather than deduce it from numerical output. The Route Viewer, developed by Argonne National Laboratory, is a two-dimensional animation model that animates the objects and events produced by a discrete event simulation. It operates in a playback mode, whereby a simulated scenario is animated after the simulation has completed. The Route Viewer is used to verify the simulation's processes and data, but it also benefits the simulation as an analytical tool by facilitating spatial and temporal analysis. By visualizing the events of a simulated scenario in two-dimensional space, it is possible to determine whether the scenario, or simulation model, is reasonable. Further, the Route Viewer provides an awareness of what happens in a scenario, when it happens, and the completeness and efficiency of the scenario and its processes. For Army deployments, it highlights utilization of resources and where bottlenecks are occurring. This paper discusses how the Route Viewer facilitates the analysis of military deployment simulation model results.
