Improving Purchasing Productivity at IBM with a Normative Decision Support System
Abstract
A computerized vendor selection system was implemented for the purchasing department of IBM's Poughkeepsie manufacturing facility. The system, called the Vendor Selection System (VSS), employs advanced mixed integer optimization techniques within a flexible but structured environment to help purchasing personnel to make better contract decisions. They can use the VSS without prior training in computer science or programming and achieve significant savings.
