A recurring problem in project management involves the allocation of scarce resources to the individual jobs comprising the project. In many situations such as audit scheduling, the resources correspond to individuals (skilled labour). This naturally leads to an assignment type project...

Die Netzplantechnik zählt zu den für die Praxis wichtigsten Gebieten des Operations Research. Insbesondere die Modelle und Methoden der Struktur- und Zeitplanung werden in vielen Fällen mit Erfolg angewendet. Vorgehensweisen der Kosten- und vor allem der Kapazitätsplanung haben jedoch...

Die Prüfung des Internen Kontrollsystems (IKS) ist eine der Hauptaufgaben bei Abschlußprüfungen. Der vorliegende Beitrag untersucht grundlegende Techniken der künstlichen Intelligenz, insbesondere regelbasierte Expertensysteme, auf ihre Eignung zur Unterstützung der Beurteilung des IKS bei...

This paper addresses methods for formulating and solving a general class of nonpreemptive resource-constrained project scheduling problems in which job durations are discrete functions of committed renewable, nonrenewable and doubly-constrained resources (multi-mode time resource tradeoff). We...

Lotsizing and scheduling comprises activities which have to be done repeatedly within MRP-systems. First, we show via a simple example the deficiencies arising within the MRP-context by neglecting the interrelationships of multi-stage systems. Second, we propose a new model for multi-item,...

Two phases can be distinguished in academic course scheduling: In phase one lectures have to be assigned to professors, whereas in phase two the lectures have to be scheduled. Here we assume that the lectures are already assigned to professors, i.e. the first phase has been done. For the second...

The discrete lotsizing and scheduling problem with setup-times is transformed into a single-machine scheduling problem, denoted as batch sequencing problem, which integrates sequence-dependent setups as well. The relationship between the lotsizing and the batch sequencing problem is analyzed....
