  3. Problem Statement • Analyze Waikiki evacuation preparedness • Given: • 30 min • 20,000 evacuees • One-way roads with choke points • County assigned disaster shelters

  4. Assumptions • Rational actors • 2 pax per vehicle • 20,000 will attempt to evac • Simplified Network • Everyone traveling at the same rate and departing at the same time • No public transportation

  5. Objective: maximize the number of evacuees during a limited laps of time (MOE) • Constraints : • Must evacuate people from starting points to shelters : Supply points • All evacuees must be directed to shelters • Can’t have evacuees in others locations than hotels and shelters • Maximum Capacity of roads and bridges (during all the evacuation time)
