Abstract
Abstract A method for re-configuring a pre-compiled discrete-event digital simulation program. The method comprises the steps of creating a template having a series of generic tasks and incorporating the template onto a computer to create a generic computer simulation. Next information associated with the steps of a process are input on the computer. The information includes the time duration of each step and the resources expended in accomplishing each step. Finally, the step information is applied to the generic computer simulation to create the discrete event simulation model of the process.
