Resource Management (MRM) 2.0 Solution Suite

WATERLOO, Ontario, June 16, 2010 (GLOBE NEWSWIRE) -- Descartes Systems
Group (TSX:DSG) (Nasdaq:DSGX), a federated global logistics network,
acquired privately-held Belgian-based Routing International nv, a
leading developer and distributor of optimized route planning

wireless mobile technology to manage resources in motion.

"Descartes is a world-class leader in MRM 2.0 solutions. The addition

enterprises of all sizes and across industries to optimize distribution
planning to improve the productivity and performance of their

advanced geocoding, historical traffic support and complex moveable and
multi-compartment routing for food service and fuel industries. Routing
International's pan-European customer base adds more than 200 members
to Descartes' federated Global Logistics Network (GLN).

MRM 2.0 is part of Descartes' Resources in Motion Management Systems
(RiMMS) initiative which recognizes the convergence of route planning
and MRM technologies into a unified solution and market. MRM 2.0
leverages the power of real-time planning and wireless mobile
technology designed to work as one. WinRoute becomes an integral part
of Descartes MRM 2.0 solution suite, and is now available to all
Descartes customers.

"Routing International and WinRoute are aligned with Descartes' culture
of serving customers," said Art Mesher, CEO of Descartes. "Like
Descartes, Routing International's success is built on making customers
successful using leading technology solutions. We look forward to
helping Routing International's customers and partners achieve superior
results using our MRM 2.0 solutions and federated GLN."
