Posted 1 month ago

Ph.D. Project to be done at KTH and Aviolinx in collaboration with Navblue – an AIRBUS company

KTH Royal Institute of Technology is represented by the division of optimization and systems theory at the department of Mathematics.

AVIOLINX provides software and services to the airline industry. Our focus is on developing innovative products and services designed specifically for the airline industry to optimize processes, reduce cost and increase revenue. Our flag ship product, N-RAIDO, is an Airline Management System that puts our customers in complete operational control of all strategic, financial and operations business processes throughout all stages of the airline operations including: Commercial planning, Flight operations, Crewing and post production analysis. AVIOLINX has a partnership with NAVBLUE. NAVBLUE, an Airbus Company, is a leading global provider of flight operations solutions which directly support millions of flights each year and help NAVBLUE’s airline customers maximize efficiency, reduce costs, ensure compliance with complex national and international safety regulations, and effectively deliver their services.

Project Description

Airline operation control involves the planning and coordination of the complex flows of aircraft, passengers and crew in airline operations. The airline industry is very competitive, and an optimized resource management is necessary to be profitable. However, it is not enough to make the schedule as efficient as possible, it should also be robust to disruptions in the operations. The disruptions could be unpredictable events such as bad weather, airport shutdowns, emergency maintenance, and in-disposable crew. These events cause immediate delays, and with a tight schedule they risk propagating through the planned flow. Delays, redirections, and cancelling of flights leads to a substantial increased cost for the flight operations and affect the customer satisfaction negatively. When a disruption occurs, it is essential that a recovery plan is formed as soon as possible so that it minimizes the propagation effects on the planned flow of aircraft, passengers and crew. Even finding a feasible flow, that satisfies the demands, is complicated, so to quickly minimize the cost of operations is very challenging and one of the main problems in the airline industry today. The online character of the problem makes it intriguing and specialized mathematical methods, algorithms and solvers must be developed to quickly respond to the disruptions.
