BUILDING STRONG ® Scarce O&M Funding Fiscal constraints are forcing the Corps to make difficult decisions concerning allocation of limited Operations and Maintenance (O&M) funds across the vast portfolio of inland navigation projects. This is driving the push towards system-based methods to ensure that limited resources are optimally distributed and benefits to the Nation are maximized.

BUILDING STRONG ® Waterborne Commerce Data  The Corps’ Waterborne Commerce Statistics Center (WCSC) collects and collates data from several sources concerning historical commercial use of US waterways. ► Dock-level, origin-to-destination routing (Corps-use-only) ► Includes tons, commodity types, vessel counts, drafts ► Aggregated data already published at project/port level  The richness of this dataset allows the performance of navigation projects to be objectively compared and also allows for rigorous, systems-based optimization strategies to be developed.

BUILDING STRONG ® Channel Portfolio Tool (CPT) CPT is a web-based decision-support package for Corps personnel at all levels to quantify the direct impacts of dredging and other O&M (in)activity on commercial shipping.

BUILDING STRONG ® Spatial Join to Waterway Network CPT spatially joins the docks in the WCSC database with the respective sub-reaches. Full network connectivity, ensuring that all transited channels are appropriately credited. Shortest-path routing used for domestic and inland river traffic transiting multiple projects.

BUILDING STRONG ® Optimization Strategies Application of Operations Research (OR) concepts to the Corps’ O&M budgeting process allows for improved system-level efficiencies to be realized. For Navigation O&M, there are interdependencies which arise due to commercial tonnage shared across projects → transportation system issues.

Certain projects seem to get funded regardless of budget ceiling, and for this example at least, they correlate fairly well with the “$/ton” heuristic.

BUILDING STRONG ® System Connectivity Analysis Presently exploring system optimization approaches for O&M budgeting of inland waterways using binary programming. Problem formulation will use results from the Corps’ Asset Management initiative to minimize the system-level risk to cargo flows.

BUILDING STRONG ® Navigation Systems Analysis The Waterborne Commerce data via the CPT gives the Corps a straightforward O&M budget formulation capability and allows for more advanced navigation systems analysis. These efforts are drawing interest from other Federal agencies (e.g. CMTS) as well as the Transportation Research Board (TRB).
