Supply chain simulation (SCS)is a strong and populartoolfordesigning,evaluating,andoptimizingthestructureofsupplychains,anditrequiresanimpor-tant task to estimate the effect of the planning to coordinate such ﬂows in SCM. Stochastic naturesexisting in the supply chain can be analyzed efﬁciently using simulation. One uses discrete-eventsimulation to model a supply chain in general. However, the nature of the supply chain system isneither completely discrete nor continuous; both aspects must be considered together in developinganSCSmodel.Inthispaper,aframeworkofdiscrete-continuouscombinedmodelingforsupplychainsimulation is proposed. Equations for the continuous aspects of a supply chain in this framework areincluded, and a simple example of the SCS model using this equation is presented.
