Lufthansa Adopts ILOG Optimization to Enhance its Crew Assignment Process

New automatic crew assignment system uses ILOG CPLEX to improve Operational Efficiency

BAD HOMBURG, Germany – April 11, 2006 – ILOG® (NASDAQ: ILOG; Euronext; SICOVAM: 006673) today announced that Lufthansa German Airlines has implemented an automatic crew assignment system which uses ILOG optimization software. Lufthansa can now create duty rosters in a more effective, responsive and cost-sensitive way – all while significantly reducing the time it takes to build crew duty rosters.

Prior to the new automatic rostering system, the crew duty rosters for 3,500 cockpit and 14,500 cabin staff were created manually. By using ILOG CPLEX, Lufthansa has streamlined the scheduling process and crew duty rosters are automatically processed. The new system takes into account costs, stability, individual crew preferences, industry and government regulatory requirements and internal corporate policies. Planners, freed from performing these tasks manually, now can use simulations to further improve the crew assignment process.

“Creating a higher amount of duty rosters of better quality and in a shorter amount of time is a big step forward and would not have been possible without ILOG CPLEX,” said Dr. Wilhelm Westerburg, IT project manager for Crew Management Systems at Lufthansa. “The automatic rostering system using ILOG optimization can solve complex problems very rapidly, allowing the schedule of a group comprised of 200 to 500 cockpit personnel, and 500 to 2000 cabin staff to be established in a matter of hours instead of days.”
