In this article, we present a family of algorithms for linear programming based on an algorithm proposed by von Neumann. The von Neumann algorithm is very attractive due to its simplicity, but is not practical for solving most linear programs to optimality due to its slow convergence. Our algorithms were developed with the objective of improving the(More)
The multimodal freight transportation planning is a complex problem with several factors affecting decisions, including network coverage, carriers and their schedules, existing contractual agreements with carriers and clients, carrier capacity constraints, and market conditions. Day-to-day operations like booking and bidding are mostly done manually and(More)
