Carmen at Deutsche Bahn
Producing reliable and cost-effective schedules for conductors and locomotive drivers at Deutsche Bahn, the world’s largest railway which employs more than 240 000 persons is definitely considered to be an extraordinary challenge. The task, which essentially means solving one of the world’s most complex planning problems, was in 2001 awarded to Carmen Systems.

Considering the positive business effects experienced by DB and the fact that both crew categories are now in production it is unmistakable that the implementation has been, to say the least, a major achievement.

Carmen at Green Cargo
The relation with Green Cargo, the largest railway cargo carrier in Sweden, has since its origin in 1995 covered increasing areas. All with a bottom-line impact enabling Green Cargo to significantly improve the operational efficiency. One of the fruits resulting from the partnership is the unique real-time system VADIS (Carmen Rolling Stock Distributor) that autonomously controls and optimizes the distribution of empty freight cars. Annual savings from this system alone are estimated to 7.8M euro. These are mainly due to:

• Decreased capital costs
• Decreased maintenance costs
• Reduced staffing requirements

Green Cargo also successfully uses Carmen Crew Pairing, Carmen Crew Rostering and Carmen Fleet Assignment.
