In process oriented simulations the simulation is defined by a collection of processes: that is the sequence of events that an entity experiences as it goes through the sys- tem. In languages which support both paradigms the process-oriented part of the model is "interpeted" or "compiled" internally as event-oriented. Rather than go into more detail here, I recommend you check an introductory text on simulation. E.g., Averill Law has a pretty good text available. Sorry, I don't have the title with me. George Fishman's Principles of Discrete Event Simulation is also good. -- Dr. Robert J Frey, Kepler Financial Management, Ltd. rjfrey@kepler.com *or* frey@chaos.sunysb.edu voice: (516) 689-6300 * fax: (516) 751-8678
