Hence, advanced algorithms are needed to solve the 2E-IRP heuristically and optimally. This paper proposes a novel exact branch-and-price algorithm for the 2E-IRP. The contributions are threefold: • We propose a mathematical model for the 2E-IRP, where customers can be visited from any ...
A Branch-and-Price Algorithm for Multi-mode Resource Leveling 227 Our Contribution. We approach the turnaround scheduling from both ends. Besides presenting a heuristic which improves on the results reported in [MMS10], we formulate a mixed integer programwhich is based on working shifts, and th...
molten iron allocation problem as an integer programming model and then reformulate it as a set partitioning model by applying the Dantzig–Wolfe decomposition. We solve the problem using a column generation-based branch-and-price algorithm. Since the ...

and availabilities. We present a branch-and-price algorithm to solve this problem. The pricing subproblems in column generation are formulated with context-free grammars that are able to model complex rules in the construction of feasible shifts for an employee. We present results for a large set...
Using Branch-and-Price-and-Cut to Solve Origin-Destination Integer Multicommodity Flow Problems We present a column-generation model and branch-and-price-and-cut algorithm for origin-destination integer multicommodity flow problems. The origin-destina... C Barnhart,Christopher A. Hane and Pamela H....
The results show that better bounds can be obtained in less computational time when compared to the state-of-the-art algorithm, especially because of the new features for the ng-path relaxation. In particular, the branch-and-price solved all the 9 instances with up to 150 vertices not ...
