One of the main points of criticism on academic research in operations research (management science) is that there is too much emphasis on the mathematical aspects of the discipline. In particular, the mathematical models that lend themselves to rigorous mathematical analysis are often rough...

Although the possibility to combine column generation and Lagrangian relaxation has been known for quite some time, it has only recently been exploited in algorithms. In this paper, we discuss ways of combining these techniques. We focus on solving the LP relaxation of the Dantzig-Wolfe master...

In designing coordination contracts, the conflict between theory and practice often appears in the form of a trade-off between the complexity of theoretically optimal solutions and their ease of implementation in the real world. In this study, we explicitly consider complexity as a design factor...
