We consider a generalization of the classical resource constrained project scheduling problem. We introduce so-called partially reiiewable resources by assuming for each resource a capacity on subsets of periods. The concept of partially renewable resources is a fundamental tool in order to make...

For most computationally intractable problems there exists no heuristic that is equally effective on all instances. Rather, any given heuristic may do well on some instances but will do worse on others. Indeed, even the 'best' heuristics will be dominated by others on at least some subclasses of...

It is well-known that for many project scheduling problems the Space AS of active schedules contains at least one optimal solution for each feasible instance, so restricting heuristic construction methods to AS will improve algorithmic efficiency without foresaking the chance to eventually find...

Since its advent, the 'just-in-time'-paradigm has considerable influence on production planning and control. While originally employed for high-volume production, 'just-in-time'-concepts are meanwhile documented for low-volume, make-to-order production as well. An example is the assembly of...

Die vorliegende Arbeit zeigt, welchen Beitrag die Koordinations- und Integrationsmechanismen des Projektmanagements zur effizienten Abwicklung von Projekten leisten können. Im Rahmen einer Taxonomie wird zwischen intrafunktionaler, interfunktionaler und interorganisationaler Koordination...

Most scheduling problems are notoriously intractable, so the majority of algorithms for them are heuristic in nature. Priority rule-based methods still constitute the most important class of these heuristics. Of these, in turn, parameterized biased random sampling methods have attracted...
