A branch-and-bound procedure for the resource-constrained project scheduling problem with partially renewable resources and general temporal constraints

Watermeyer, Kai; Zimmermann, Jürgen - In: OR Spectrum 42 (2020) 2, pp. 427-460

In this paper, we consider the resource-constrained project scheduling problem with partially renewable resources and general temporal constraints. For the first time, the concept of partially renewable resources is embedded in the context of projects with general temporal constraints. While...

Mixed-integer linear programming for resource leveling problems

Rieck, Julia; Zimmermann, Jürgen; Gather, Thorsten - In: European Journal of Operational Research 221 (2012) 1, pp. 27-37

We consider project scheduling problems subject to general temporal constraints, where the utilization of a set of renewable resources has to be smoothed over a prescribed planning horizon. In particular, we consider the classical resource leveling problem, where the variation in resource...
