Mercury Scheduling Systems Inc. - DHL and Maersk Airlines Live With Magellan.

Business Editors

VANCOUVER, British Columbia--(BUSINESS WIRE)--May 30, 2001

Over the past month both DHL Airways and Maersk Air have completed the transition of their day-of-operations crew management systems to Mercury's real-time Magellan solution. DHL and Mearsk have been engaged in an exhaustive proving phase where Magellan has been tested thoroughly in parallel mode against the previous scheduling systems. With testing completed, all live interfaces have been transferred to the Magellan day-of-operations scheduling system. Mercury's software solution now enables both airlines to operate in a real-time problem solving environment incorporating crew scheduling, government regulations, union requirements, training requirements, and the flight crew's own personal schedule requests via the internet. DHL also uses Mercury's Nova crew rostering and bidding system and was the lead customer for the Orion crew communications solution, the airline industry's first fully interactive internet and voice activated system providing real time communications with a day-of-operations solution. This application eliminates the bulk of the crewmembers' need to contact the airline's crewing department for routine information, allowing crew schedulers to concentrate on more urgent issues. The system provides for two-way communication such that crews can acknowledge receipt of change notices upon logging on, again reducing crew schedulers non-productive activities and allowing for quick and easy dissemination of information during periods of severe disruption when timely accurate communications are imperative to restore the operation to plan.

DHL Airways Inc. serves all U.S. destinations for DHL Worldwide Express, the world's largest international air express network. With over 68,700 employees and 254 aircraft worldwide, DHL Worldwide Express links more than 635,000 destinations in over 228 countries.

Maersk Air completed the switch over to Magellan on April 1, 2001 in compliance with new Danish government rules, which their existing legacy system could not implement. Mercury is pleased to have completed the Magellan installation on schedule and for the continuation of its good relationship with Maersk, who has been a fundamental part of the Magellan development since its inception. With Magellan live at Maersk, the airline is now running Mercury's complete set of crewing solutions including Cygnus pairing optimizer, Nova crew rostering, Nova OnLine internet bidding system, and Magellan day-of-operations system.
