Passenger and resource reaccommodation in the wake of a delay costs the airlines -- an industry that operates on less than two percent profit margins -- billions of dollars each year. A reduction in delays, cancellations and their cascading downstream impacts would greatly benefit the U.S. airline industry and travelers, the researchers said.
The study, published in the journal Computers and Operations Research, looks at early phase flight schedule and aircraft route planning. It takes a proactive approach in designing cascade-resistant schedules, rather than the reactive approach of trying to manage delays after they occur.

"There is an overwhelming amount of data generated from airline on-time performance records," said Lavanya Marla, an industrial and enterprise systems engineering professor and lead author. "It is challenging to find the best model to quantify the uncertainty in the aviation system in order to improve on-time performance and cost savings. Our research shows that the existing models are unable to distinguish the cascading downstream impact of one solution over another, which is critical to the airlines for decision-making."
The team, which also includes Vikrant Vaze, a professor of engineering at Dartmouth College, and Cynthia Barnhart, chancellor and a professor of engineering at the Massachusetts Institute of Technology, used historical data from U.S. airlines to tweak aircraft routing to help prevent and minimize delays from the extent to which they exist today.

Aircraft routing refers to the route that a single aircraft takes between Federal Aviation Administration-mandated maintenance checks that typically occur on a 72-hour cycle and multiple flights. The team hones...
