SCOTTSDALE, Ariz. -- JDA(R) Software Group Inc. (Nasdaq:JDAS) announced today that Stephen C. Graves, Ph.D., a professor at MIT's Sloan School of Management, will serve as JDA's chief science advisor. A renowned authority in the field of supply chain optimization, Graves has engaged in several initiatives with JDA that have delivered significant ROI for the more than 600 retail and supply chain customers that rely on JDA Portfolio(R) merchandise and distribution optimization software solutions. In this newly created role, Graves will provide ongoing expertise and visionary thinking to further JDA's leadership position in embedding sophisticated mathematical techniques and demand intelligence in its software to advance its customers' enterprise planning, forecasting, replenishing, assorting and overall business execution processes.

"We're constantly striving to find more effective ways to get the optimum amount of product from supplier to shelf in the most efficient and profitable manner," said Peter Charness, JDA's chief product officer and senior vice president of global marketing. "While JDA already employs a highly specialized team experienced in elaborate mathematical models and statistical concepts, Steve Graves' work at MIT puts him at the forefront in uncovering research models and methods that we believe will accelerate our efforts even further. Now we have the best minds in the country focused on our next generation of optimization solutions, designed to deliver a high return on investment for our customers," added Charness.

"Over the years I've collaborated with JDA developers and witnessed firsthand JDA's dedication to solving real-world problems related to strategic inventory positioning challenges," said Graves. "I am now excited to work with JDA customers and consultants on a next-generation forecasting and replenishment infrastructure that will open new doors for supply chain advancement and optimization."

Graves will also be a key advisor to JDA's new Demand Optimization Council. Primarily comprised of JDA customers in the retail, wholesale and manufacturing industries, the Demand Optimization Council will provide input regarding the strategic direction, design and development of JDA's demand-driven, predictive and optimization solutions.
