Operational constraints control system

  • 4000 automated workstations
  • The average number of aircraft changes per flight in the operational window was reduced by 15%
  • The range of “sustainable” assignment of aircraft outside the operational window was extended from 72 hours to 7 days
Система контроля операционных ограничений

Prerequisites for implementation and problems

Employees manually controlled the operational environment indicators for execution of passenger flights, while existing systems took the cross-influence of factors only partially into account. This led to larger labor costs and flight delays.

Project goals

Centralized and automated processing of constantly changing factors - deferred defects, the nature of transported baggage, weather, crew qualifications
Increased speed of operational decision making, for example, aircraft replacement
Reduced delays in flight performance, optimized use of the airline’s fleet

Implementation complexity

  • Integration with a variety of production systems, online processing of heterogeneous information
  • Development of a flight model that takes various factors such as aircraft characteristics, passengers, baggage, cargo, and airport capabilities into account
  • The global nature of the project. About 4,000 workplaces of production department employees, airline’s representatives at airports, flight attendants and pilots have been automated


The implementation of the operational constraints control system made it possible to:

  • obtain comprehensive information about a planned flight from a variety of production systems;
  • automatically take into account the relationship between different factors of the flight based on customizable rules;
  • pre-form operational restrictions for a specific flight;
  • promptly inform staff about the need to make adjustments to flight planning;
  • reduce the number of errors of personnel who manually control such factors.

About the project

“The Operational Restrictions Control System is a project that is unique for the aviation industry, as it is a superstructure above a variety of production systems and allows setting flight restrictions based on a visual rule constructor. This makes it possible to transfer functions of setting and analyzing data to line employees and flexibly respond to changes in the airline’s operating conditions. The project is a development of the Data Lake concept, in which the use of a large array of heterogeneous production data enables the achievement of a synergistic effect and implementation of functions that are not available in the existing production systems (MRO, flight planning, etc.)”
