Multiplicity and complexity issues in contemporary production scheduling

N. Brauner, Y. Crama, A. Grigoriev, J. van de Klundert
2007 Statistica neerlandica (Print)  
High multiplicity scheduling problems arise naturally in contemporary production settings where manufacturers combine economies of scale with high product variety.  ...  The paper extends the framework presented in Brauner et al. (2005) for single machine, non preemptive high multiplicity scheduling problems, to more general classes of problems.  ...  A job-oriented description of the schedule describes the complete routing of a job through the shop. The mapping S M T (k, t) describes the state of machine k at time t.  ...

On the generation of circuits and minimal forbidden sets

Frederik Stork, Marc Uetz
2004 Mathematical programming  
Our motivation to study these problems is their relevance in the solution of resource constrained scheduling problems, where an independence system arises as the subsets of jobs that may be scheduled simultaneously  ...  We are interested in the circuits of this system, the so-called minimal forbidden sets, which are minimal subsets of jobs that must not be scheduled simultaneously.  ...  We appreciate the input of two anonymous referees. Particularly the deep remarks of one of them greatly improved our understanding of several issues; he also suggested the simplified Example 1.  ...
