Brazilian Air Force Uniform Distribution Process: Using Lean Thinking, Statistical Process Control and Theory of Constraints to Address Improvement Opportunities.

摘要

In the Brazilian Air Force, all enlisted Soldiers and Corporals (corresponding to USAF ranks from Airman Basic to Senior Airman) are entitled to receive their uniforms from their assigned, respective organizations, free of charge. An important portion of the uniform s distribution process is accomplished by the Brazilian Air Force Intendancy Central Depot (ICD). This organization carries the uniform inventory and performs the selection and distribution activities, following the guidance of the Sub-directorate of Supply. ICD process performance data for the peak distribution seasons of 2012 and 2013 was collected and analyzed. Several indications of inefficiencies became apparent, exemplified by a high number of late and partially fulfilled orders. This study applied fundamental principles of Lean Thinking, Statistical Process Control and the Theory of Constraints to identify potential areas for process improvement. Through statistical analyses, a simulation effort and capacity analysis, the negative impacts of variability throughout the process were assessed and several types of waste were recognized. Potential solutions to address the problems identified were suggested, as well as areas for further research
