much investigation has been given to this issue, the role of setup savings from the perspective of the workload control concept has hardly received attention. This paper reports a simulation study on this matter. The study evaluates the potential for savings in setups, dependent on the level of workload in the shop, for two alternative strategies, namely considering setup times centrally, withi...

This paper presents a heuristic algorithm for solving the job-shop scheduling problem with sequence dependent setup times (SDST-JSSP). The algorithm relies on a core constraint-based search procedure, which generates consistent ordering of activities requiring the same resource by incrementally imposing precedence constraints on a temporal feasible solution. Key to the effectiveness of the sear...

Resource-constrained project scheduling with activity pre-emption assumes that activities are allowed to be interrupted and restarted later in the schedule at no extra cost. In the current paper, we extend this pre-emptive scheduling problem with setup times between activity interruptions and the possibility to fast track pre-emptive subparts of activities. The contribution of the paper is twof...
