Profit-oriented scheduling of resource-constrained projects with flexible capacity constraints

Schnabel, André; Kellenbrink, Carolin; Helber, Stefan - In: Business research 11 (2018) 2, pp. 329-356

We consider a novel generalization of the resource-constrained project scheduling problem (RCPSP). Unlike many established approaches for the RCPSP that aim to minimize the makespan of the project for given static capacity constraints, we consider the important real-life aspect that capacity...
