Minimum Formwork Stock problem on residential buildings construction sites

The Minimum Formwork Stock problem (MFS) consists in minimizing the quantity of shuttering materials needed for a construction site. This paper introduces this problem encountered in a French building company and presents two different solving approaches: a constraint programming model combined with a constructive heuristic and a Dantzig–Wolfe decomposition taking advantage of the size of real world instances. Then, a NP-hardness proof of the problem is established before providing results on real instances.
