  • ML/AI Based Feedback Loop for Airline Operations

    Developing an intelligent feedback system for airline operations that leverages cloud infrastructure, automated data pipelines, compelling visualization, and advanced AI/ML techniques. The objective of this system is to apply advanced data science techniques to systematically and rapidly learn from past events by relating outcomes to contextual information for the purpose of objectively assessing performance, creating scenario-based decision making, and capturing meaningful data to support…

The objective of this system is to apply advanced data science techniques to systematically and rapidly learn from past events by relating outcomes to contextual information for the purpose of objectively assessing performance, creating scenario-based decision making, and capturing meaningful data to support upstream planning functions.

  • Probabilistic Decision Making

    Created an innovative framework for incorporating weather uncertainty into airline operational decision making. Established and directed a unique collaboration between The MITRE Corp, The Weather Company, IBM, and American Airlines to design and build a probabilistic decision-making framework that was tested against a real operational scenario (e.g. cancellation decisions during FAA Ground Delay Programs).

  • Collaborative Trajectory Options Program and Arrival Fix Balancing

    Led the conceptual design, development, and deployment of a solution for managing airport arrival fix demand and capacity imbalances. This system works with FAA automation and internal flight planning systems to optimize the selection of alternative routes that minimize airspace arrival congestion and delay.

  • Diversion Planning, Tracking, and Recovery

    -

    Developed and implemented a comprehensive diversion management program including decision support tools for planning, tracking, and recovery of flight diversions. This effort also included development of an automated post-event analysis tool for better understanding and evaluating operational effectiveness during disruptions.

  • Flight Cancellation Advisor

    -

    Developed and deployed a real-time schedule reduction tool for generating cancellation plans for addressing operational irregularities caused by snow or convective weather. Plans are constructed to minimize impact on passengers, crew, and aircraft routings using an approach that combines subject matter expertise with mathematical optimization techniques.

  • FAA Ground Delay Program Slot Optimizer

    -

    Developed and deployed decision support for arrival slot management during FAA-mandated Ground Delay Programs (GDP’s). This tool identifies operational problems related to crew, curfew, and critical connections and contains logic for optimizing slot assignments to resolve crew legalities and to minimize critical passenger misconnections. It was subsequently been enhanced to recommend an optimal mix of cancellations and delays to minimize passenger re-accommodation delays.

    "Improved Decision Making for Disruptive Weather Events using Ensemble Forecasts"
    John Williams, Mike Robinson & Tim Niznik, IBM, MITRE & American Airlines

    Decisions made in the absence of probability-based analytics will not just usually be wrong, they will consistently be sub-optimal, especially when those decisions involve weather. An increasingly important need for both airline operation centers (AOC’s) and air traffic management (ATM) is for improved response to weather events…

    "Improved Decision Making for Disruptive Weather Events using Ensemble Forecasts"
    John Williams, Mike Robinson & Tim Niznik, IBM, MITRE & American Airlines

    Decisions made in the absence of probability-based analytics will not just usually be wrong, they will consistently be sub-optimal, especially when those decisions involve weather. An increasingly important need for both airline operation centers (AOC’s) and air traffic management (ATM) is for improved response to weather events, specifically in terms of quantifying the level of risk around potential courses of action. What is needed is a practical, data-driven process that explicitly considers weather uncertainty in balance with the costs and risks for decision options. Such a capability would yield more consistent and efficient ATM initiatives and AOC responses that reduce avoidable delay, flight cancellations, costs, and passenger disruption. This talk brings together the perspectives of The MITRE Corporation, The Weather Company, and American Airlines who will present a framework to “bridge the gap” from deterministic to probabilistic decision-making using ensemble weather forecasts and multiple “trajectories” of possible weather constraint scenarios.

    "Probabilistic Decision Making and Airline Operations: Why it Pays to Play Games of Chance"

    Decisions made in the absence of probability-based analytics will not just usually be wrong, they will consistently be wrong, especially when those decisions involve weather and ATC. One of the objectives of our Decision Support Vision for the Operations Control Center is to improve how we respond to weather events, specifically in terms of the determining the timing, level of risk, and specific actions to take. We need to move away from deterministic decision making that is primarily ad-hoc and experience-based to a more data-driven process that is built on predictive analytics and accounts for uncertainty. This talk looks at some examples where probabilistic decision making could be applied, some examples in the industry of where these techniques are already being applied, and finally, our current efforts to develop this capability internally.

    "A New Approach to Airline Hub Disruption Management"

    Severe thunderstorms at an airport can result in ramp closures, extensive Air Traffic Control delays, and flight diversions, all of which can lead to major disruptions of a flight schedule, especially when that airport is one of your major hubs.

    "A New Approach to Airline Hub Disruption Management"

    Severe thunderstorms at an airport can result in ramp closures, extensive Air Traffic Control delays, and flight diversions, all of which can lead to major disruptions of a flight schedule, especially when that airport is one of your major hubs. In an effort to better manage such events a new decision support tool was developed to both predict and respond to degraded airport capacity, gate congestion, customer connectivity, and other operational constraints such as crew legality and curfew restrictions. This talk will discuss how the ability to anticipate operational irregularities before they actually occur combined with the ability to dynamically generate a new flight schedule in minutes has resulted in a significant shift in the disruption management philosophy at American Airlines.

    “Attila the Hub: Decision Support for Airline Hub Reduction”

    We discuss the development and implementation of an automated tool that identifies alternative cancellation plans to address operational irregularities such as those caused by snowstorms, thunderstorms, and ATC ground delays. These plans are constructed so as to minimize the impact on passengers, crew, and aircraft routings using an approach that combines subject matter expertise with mathematical optimization techniques.

    The most intensive form of routine aircraft maintenance, known as a “D-Check”, occurs every 6-8 years or approximately every 20,000 flight hours, involves thousands of tasks, and costs between $1-$2 million. Scheduling the tasks during such an event is typically performed by hangar supervisors and crew chiefs who use experience and judgement…

    "Network-Based Methods for Large-Scale Resource Constrained Task Scheduling Problems with Applications to Aircraft Maintenance at American Airlines"

    The most intensive form of routine aircraft maintenance, known as a “D-Check”, occurs every 6-8 years or approximately every 20,000 flight hours, involves thousands of tasks, and costs between $1-$2 million. Scheduling the tasks during such an event is typically performed by hangar supervisors and crew chiefs who use experience and judgement to make decisions about what tasks to do, when to do them, and with which resources. This presentation discusses a modeling approach and solution algorithm for overhaul task scheduling, with the objective of minimizing aircraft downtime and reducing overtime labor costs.
