Since June 2004, EMS has employed advanced knowledge management practices, statistical analysis and modeling and simulation tools, to complete commercial supply chain and government transportation applied research, development, and analysis.
The analysis completed by EMS has been documented in numerous published reports, white papers, and presentations. Several of the papers and studies are available through links on this website.
One of the unique strategy and analysis tools being continuously enhanced by EMS is the National Integrated Inter-modal Modeling Tool (NIIM-T), which is a detailed node-arc network representing the national transportation infrastructure and modal interchange processes. NIIM-T was created by EMS to support analysis and policy development related to inter-modal facilities: airports, seaports, and rail terminals. The inter-modal facilities, which are represented as nodes in the model, are connected by the national air, rail and highway networks, which are represented as arcs in the model.
NIIM-T provides the flexibility to examine transportation issues at the level of detail the planner needs. NIIM-T is being developed to allow for the examination of local conditions at the micro-level while consolidating connecting corridors and nodes on a macro scale - thus allowing local models to be attached to regional and national nodes of interest as well. Through a modular design approach, planners can evaluate defined areas of interest in detail, and still view the regional, national, or international links that effect transportation activities at relevant levels of detail.
