Agent-Based Dantzig-Wolfe Decomposition
, 2009 We present an agent-based approach to Dantzig-Wolfe column generation (a decomposition approach), which is applied to an integrated production, inventory, and distribution routing optimization problem.

International Journal of Satellite Communications and Networking, Volume 42, Issue 4, Page 286-312, July/August 2024.This paper presents solution techniques that find beam patterns and frequency allocation for GEO high‐throughput satellites and maximize the total demand met across all users. An integer program is used to select an optimal set of beams from a pool of candidate beams generated by our new algorithms.

Decision support for the technician routing and scheduling problem
Networks, Volume 83, Issue 1, Page 169-196, January 2024.Abstract The technician routing and scheduling problem (TRSP) optimizes routes for technicians serving tasks subject to qualifications, time constraints, and routing costs. In the literature, the TRSP is solved either to provide actual technician work schedules or to perform what‐if analyses on different TRSP scenarios.

Dantzig—Wolfe Decomposition of Variational Inequalities
The creation and ongoing management of a large economic model can be greatly simplified if the model is managed in separate smaller pieces defined, e.g. by region or commodity.

International Journal of Intelligent Systems, Volume 2024, Issue 1, 2024.This study identifies critical inefficiencies within a dual‐channel operation model employed by a fast fashion company, particularly the independent operation of three logistics distribution systems. These systems result in high operational costs and low resource utilization, primarily due to redundant vehicle dispatches to meet the distinct demands of

Simplicial with truncated Dantzig-Wolfe decomposition for nonlinear multicommodity network flow problems with side constraints [PDF]
, 2000 The simplicial decomposition (SD) subproblem for a nonlinear multicommodity network ow problem is simply its linear approximation. Instead of solving the subproblem optimally, this paper demonstrates that performing one iteration of Dantzig-Wolfe ...

A New Dantzig-Wolfe Reformulation And Branch-And-Price Algorithm For The Capacitated Lot Sizing Problem With Set Up Times [PDF]
The textbook Dantzig-Wolfe decomposition for the Capacitated LotSizing Problem (CLSP),as already proposed by Manne in 1958, has animportant structural deficiency.
