Why Traditional APS Falls Short
• Based on deterministic times and no unplanned events - leads to optimistic plans/schedules that cannot be achieved in practice – goes from feasible to infeasible over time
• Decision makers have no basis for judging the risk associated with a plan/schedule.
• Accurately predicting delivery dates with a high level of confidence is difficult if not unattainable

Simio RPS (Patent Pending)
• RPS is the dual use of a simulation model to generate both a realistic and detailed plan and an assessment of the risk associated with that plan.
• Simio adds variation to processing times and incorporates unplanned events and automatically replicates the model (across processors) to generate risk measures. – Probability of meeting target.
– Expected completion time.
