Release Details

CAMBRIDGE, Mass.--(BUSINESS WIRE)--June 9, 2004-- Aspen Technology Inc. (Nasdaq: AZPN) today announced the availability of a new release of its supply chain solutions for the chemicals, polymers, pharmaceuticals and consumer goods industries. Release 5.0 of the Aspen Supply Chain Suite features new functional and integration capabilities that enable process manufacturers to optimize supply chain performance by creating Demand-Driven Supply Networks (DDSN). The new solutions further improve upon the market's fastest optimization time, and incorporate industry best practices through pre-configured application modules.

Key new capabilities provided by the solutions include multi-user collaborative planning and scheduling, and enhanced web-based collaborative forecasting. These capabilities are critical to responding quickly to market changes in operating environments with multi-stage manufacturing processes and parallel scheduling roles. They enable planners and schedulers to generate optimal results based on the most current and accurate information available, while minimizing planning cycle times.

"This release of the Aspen Supply Chain Suite gives process manufacturers unprecedented enterprise planning and scheduling capabilities," said Steve Pringle, Sr. Vice President Manufacturing and Supply Chain, AspenTech. "Until now, supply chain solutions that could handle the huge quantities of data required to capitalize on a dynamic marketplace simply didn't exist. Our clients are now able to manage their supply networks, from planning to the shop floor, using the latest production and demand data."

The new integration components transport real-time data between enterprise resource planning (ERP) systems, manufacturing execution systems (MES), and the AspenTech supply chain solutions. This enables decisions to be made with the most current data possible and then instantly communicated to execution systems, dramatically improving the organization's ability to respond. The components incorporate pre-configured data integration templates for leading ERP systems that substantially reduce implementation time and effort.

Additional improvements in the new release include an upgrade to the core technology with features such as a revised graphical user interface, support for eight languages and algorithmic enhancements. New process industry-specific functions include collaborative price-adjusted revenue forecasting and shared resources in planning and scheduling. The solutions significantly upgraded in release 5.0 include: Aspen Collaborative Forecasting; Aspen Demand Manager; Aspen Supply Planner; Aspen Distribution Scheduler; Aspen Inventory Planner; Aspen Plant Planner and Scheduler; Aspen Plant Scheduler; and Aspen Strategic Analyzer. Regional seminars are being scheduled to educate clients and partners on the complete solution family.
