The study reports the results of a transshipment linear programming analysis applied to export shipments of dry peas via the Columbia/Snake navigation system in the Pacific Northwest (PNW). Similar analyses have been applied to bluegrass seed and lentil exports, but for the sake of brevity only the results for dry peas are reported here (Bahn and Jones, Belcher). The analysis identified least-cost modes and alternative routes encompassing combined inland and ocean movements under several alternative transportation conditions. It also identified inland origins of shipments and optimal port transshipment points. The primary objective of our study was to examine intermodal transportation systems, specifically container-on-barge, barge-carrying vessel, and minibridge, by comparing them with traditional transportation systems. A secondary objective was to introduce two factors potentially affecting the rate structure--waterway users' fees and higher container handling charges--to assess the sensitivity of the model results to changes in rates or charges. Another important aspect of the model was that it permitted the inclusion of port charges in the analysis of export movements by specifying shipments from interior land points to overseas destinations.
