About Us

CTI has been building optimization systems for more than a decade. We have a long history with Qantas (before that Australian Airlines) and Australian Rail Track Corporation.
Over the years CTI has built systems for these clients in the following areas:

  • Operations Control
  • Crew Planning
  • Crew Rostering
  • Schedules Planning
  • Fleet Assignment
  • Disruption Management
  • Warehouse Management
  • Maintenance Management

In 2006, the company embarked on a major exercise to productise these applications and the results are standard, configurable products and components that can be used stand alone or integrated into 3rd party solutions.

The first application of the new products within the Rail Industry was with Pacific National and Jet Airways within Aviation. We have since provided software and services to customers including Etihad AirwaysOman AirlinesMalaysian Airlines and Sydney Trains.

CTI has expanded our product range by acquisitions of rail software products that are now used by large Australian railways and airport terminal management systems that are used by many large international airports.

Constraint Technologies is constantly working on forming new partnerships and improving our business even further.
