We present the first known polynomial time approximation schemes for the non-preemptive case of several identical parallel machines scheduling problems with ...

A scheduling problem in which the processing times of the jobs can be reduced at some expense is called a scheduling problem with controllable processing times.

Approximation schemes for parallel machine scheduling problems with controllable processing times. KJKlaus Jansen. Klaus Jansen. Monaldo Mastrolilli.

Approximation schemes for job shop scheduling problems with controllable processing times. February 2005 · European Journal of Operational Research.

Approximation schemes for parallel machine scheduling problems with controllable processing times. We consider the problem of scheduling n independent jobs ...

This note studies a unrelated parallel-machine scheduling problem with controllable processing times and job-dependent learning effects.

The problem is to find a schedule of the jobs and a processing time reduction tij (tij 6 uij) for each job j if it is processed on machine i such that the total ...

Feb 25, 2015 · In this paper, we study the parallel machine scheduling problems with controllable processing times and preemption. We assume that the extra ...

Downloadable (with restrictions)! In this paper the approximability of parallel machine scheduling problems with resource consuming jobs is studied.

Nov 14, 2009 · We study scheduling problems with controllable processing times on parallel machines. Our objectives are to maximize the weighted number of ...
