Civil aircraft manufacturer Learjet, a subsidiary of Canadian-based Bombardier Aerospace, will use Optum Inc. to enhance its supply chain efficiency. Optum will work with consultants Arthur Andersen to address Learjet's major logistics challenge -- improving the management and control of components at its Wichita, Kan. facility. Learjet will use Optum's warehouse management software (WMS) to manage aircraft part inventory levels as well as improve receiving and shipping processes. The distribution software will enable Learjet to track in real-time and maintain line-item detail for individual aircraft components as the parts move from stock to the assembly floor. The company expects to improve its ability to complete aircraft assembly on time, reduce aircraft downtime, and increase customer satisfaction in maintenance operations. "Bombardier is looking to leverage supply chain automation and real-time inventory visibility to improve our manufacturing and service operations, and work more quickly and profitably," says Alan Young, director of work and material planning at Bombardier Aerospace. "With Optum software, we can reach world class levels of logistics and inventory support."
