PARIS and MOUNTAIN VIEW, Calif., July 20, 2005 --ILOG® (NASDAQ: ILOG; Euronext: ILO, ISIN: FR0004042364) today unveiled Optimization Decision Manager (ODM), for interactive business planning and scheduling applications. ILOG ODM is the first software tool that automatically generates custom planning and scheduling applications that can save organizations millions of dollars in operating costs and dramatically increase their responsiveness to business change. ILOG ODM is also the first optimization-based application development tool that lets business users configure and modify the applications that will drive their operational decision making. Leveraging ILOG’s experience creating user-driven applications based on business rules (BRMS), ILOG ODM lets business users create, test, and compare scenarios before committing to a particular plan or schedule.

Targeting businesses that want to develop standalone optimization-based decision support applications, ILOG ODM allows users to create plans and schedules that accurately match business realities because it enables them to take into account all of the costs, operating constraints, customer requirements, employee preferences and goals inherent in economic planning and the operational management of complex schedules. These benefits are possible due to the use of powerful optimization software “under the hood ” including ILOG CPLEX®. ILOG ODM will widen the use of optimization by unlocking the power of math-based planning and scheduling for business users.

ILOG ODM introduces many innovations to the planning and scheduling process. Since businesses rarely make major decisions about resources without testing their ideas first, ODM provides “out of the box” what-if analysis and scenario comparison so that users can understand the impact of change on their business. ILOG ODM allows business users to adjust assumptions, operating constraints and goals for planning and scheduling resources and see the results in familiar business terminology, allowing them to identify the best strategy for a range of business problems, such as where to locate warehouse distributions centers, whether to build a new plant or assembly line, or how to schedule staff optimally while considering customer service requirements, labor laws, skills requirements and employee preferences. Business users can interact with the system and have greater insights into the underlying conflicts and economics and more faith in the recommended schedule or plan.

“We have long depended on the power and reliability of ILOG CPLEX for solving our toughest optimization problems, and we are delighted to see ILOG make this valuable technology easier to use with the introduction of ILOG Optimization Decision Manager,” said Pano Santos, senior scientist, HP Labs in Palo Alto, Calif. “We believe that ILOG’s out-of-the-box support for ‘what-if analysis’ and scenario comparison will help us develop better models and create decision support applications with ease.”
