New Modeling Issues• Service rather than manufacturing system — canstill use many of the same ideas, constructs• More complex — need more detailed modeling• Nonstationary arrival process– Often need to represent it for model validity– Appealing (but wrong) approach• Keep track of current arrival rate• Generate next interarrival as EXPO [1/(current arrival rate)]• See text for explanation of why this is wrong– Useful probabilistic model: Nonstationary Poisson Process(NSPP)<strong>Simulation</strong> <strong>with</strong> <strong>Arena</strong> — Chapter 8 — Detailed Modeling 8 - 12
