Problems solved by technology

[0011] Furthermore, none of the above work provides a sea transport program that optimally maximizes the total net surplus (as opposed to merely minimizing cost) for transport schemes
The cost minimization approach alone does not always provide the fullest results, as it does not properly represent the economic impact of ship assignment decisions, does not properly reflect the trade-off between contract and spot ship use, and did not rate long and short voyages on a consistent basis

[0025] definition

[0026] All words in this specification are intended to have their broadest ordinary meanings. For further clarity, the conventional meanings of some terms used in this specification are set forth below.

[0027] "Allocation" means assigning available goods to various demand locations based on some preference (eg, economic) in order to satisfy destination requirements while satisfying existing constraints and limitations.

[0028] "Blending Ratio" means the set of constraints that limit the mixing (or blending) of supply grades of bulk materials (e.g., crude oil) that, when delivered on a single vehicle, are critical for demand location segregation (e.g., port segregation ) is acceptable.

[0029] "Bulk material" means any material that is unbound and substantially liquid when loaded; in other words, it is in loose, unencapsulated form. Examples of bulk materials include coal, grain and petroleum products.

[0030] "Cargo" means any product or material...

Abstract

A method and apparatus for optimal transporting of cargo is provided. The method includes optimizing a plurality of transportation decisions and mechanically transporting cargo through movement of a plurality of vehicles in accordance with a set of optimized transportation decisions. The decisions include transportation routes and schedules for the transportation vehicles, allocation of cargo to be transported to one or more demand locations by the transportation vehicles, nomination of cargo pickup by the transportation vehicles from the one or more supply locations, the use of specialized transportation locations, and vehicle assignments for each of the transportation vehicles.; The set of decisions is optimized by collecting data relating to the various transportation decisions, using the data collected as part of a mixed integer linear programming model, and obtaining a solution to the model to arrive at a set of optimized transportation decisions.
