Repair Process Improvement at the Ogden Air Logistics Center, Landing GearDivision: A Case Study in the Application of the Theory of Constraints

摘要

This study explored the nature and extent of success that resulted from theimplementation of the Theory of Constraints (TOC) in a depot repair environment. The actions taken to implement TOC were determined. Performance measures which defined success were identified and data were collected and summarized to demonstrate performance before and after implementation of TOC concepts. Improvements in flowdays and work-in-process (WIP) were determined to be attributable to the TOC effort. In addition, the unique characteristics of probabalistic repair and supply system variability were noted as those characteristics that posed the greatest challenges to implementing TOC in a remanufacturing environment. Despite these challenges, analysis revealed that the Landing Gear Division at Ogden Air Logistics Center (ALC) successfully implemented TOC concepts and improved performance within the wheel repair process in terms of the performance measures defined.
