The proactive scheduling approach aims to generate a robust schedule minimizing the impact of disruptions, which may cause a schedule delay, on the primary performance measure of the predictive schedule. One of the simplest ways to absorb delays is to insert buffers or unforced idle times into the schedule on the basis of a minimum perturbation strategy. This paper proposes the concept of a dummy job aiming to build a generic model for proactive scheduling under the minimum perturbation strategy and the framework of dummy job based scheduling. Through some computational experiments, we clarify some properties of a predictive schedule on which dummy jobs are allocated. Finally, we discuss the applicability of dummy jobs to shop scheduling problems.
