Scheduling preemptable jobs on identical processors under varying availability of an additional continuous resource

Rafał Różycki, Grzegorz Waligóra, Jan Węglarz (2016)

International Journal of Applied Mathematics and Computer Science

Similarity:

In this work we consider a problem of scheduling preemptable, independent jobs, characterized by the fact that their processing speeds depend on the amounts of a continuous, renewable resource allocated to jobs at a time. Jobs are scheduled on parallel, identical machines, with the criterion of minimization of the schedule length. Since two categories of resources occur in the problem: discrete (set of machines) and continuous, it is generally called a discrete-continuous scheduling...

Multicriteria scheduling problems: a survey

V. T'kindt, J.-C. Billaut (2010)

RAIRO - Operations Research

Similarity:

This paper presents a state-of-the-art survey on multicriteria scheduling and introduces a definition of a . It provides a framework that allows to tackle multicriteria scheduling problems, according to Decision Aid concepts. This problem is decomposed into three different problems. The first problem is about obtaining a model. The second one is how to take criteria into account and the third one is about solving a scheduling problem. An extension to an existing notation for...

Scheduling jobs in open shops with limited machine availability

Jacek Błażewicz, Piotr Formanowicz (2010)

RAIRO - Operations Research

Similarity:

In this paper, open shop scheduling problems with limited machine availability are studied. Such a limited availability of machines may appear in many real-life situations, as preventive maintenance activities. Three types of jobs are distinguished: non-preemptable, resumable and preemptable. An operation of a resumable job if not completed before a non-availability period of a machine may be suspended and continued without additional cost when the machine becomes available. In the...
