Outline D Background, Motivation and our Contributions a Overview of Robust Airline Schedule Planning a Robust Aircraft Maintenance Routing -reduce delay propagation O Flight Schedule Retiming- reduce passenger missed connections

Summary Lecture #2 Achieving good passenger service reliability at an acceptable operating costs Disrupted passengers suffer long delays on average(320 minutes) versus non disrupted passengers(14 minutes) Connecting itineraries have a much higher risk of being disrupted than local itineraries(2.7x) Late disruptions are often difficult to recover the
