Abstract: A freight logistics efficiency modeling software embodied in a system and a process for implementing the software. The software interface allows an interactive, visual, user-defined freight transport supply model to be created at the instructions of the user. The model includes a seaport node, hinterland nodes, transportation links that represent transport pathways between nodes, and transportation transition nodes to represent discrete alterations of transport performance along transport pathways. The present invention allows a user to model logistics chain from a low level of abstraction, and to create highly effective theoretical alterations of existing models to examine proposed changes to an existing logistics chain. The use of existing standards allows completion of a model lacking complete data values, and further allows comparison of existing logistics chains to benchmark logistic chain performance and normal logistic chain performance.
