A system which includes overt instances of preemptive scheduling, or which requires the use of preemptive scheduling to model the system, can pose difficulties to a modeler. By preemptive scheduling we mean having to reschedule or cancel a previously scheduled event (or activity completion). The difficulties in modeling preemptive scheduling stem from the highly stylized constructs which simulation languages provide for such operations. This paper describes these difficulties, reviews an approach which can reduce the difficulties for some applications, and presents an approach which can be used to model preemptive scheduling, using only simple simulation language constructs.
