Abstract:

The purpose of this study was to identify and provide pipeline managers with the knowledge and tools necessary for reducing process variation associated with retrograde asset flow time. Several Air Force studies have been devoted to researching portions of the pipeline process. Our study continues this trend of investigations by studying the Base Processing Segment. This study demonstrates the potential for analyzing the Base Processing Segment of the depot-level reparable pipeline using Statistical Process Control. Retrograde asset flow time data collection methods and current management practices were examined. Control charts were used in the passive mode to analyze and determine the statistical stability of the Base Processing Segment. Control charts were used in the active mode in a one-factor experiment that demonstrated the techniques for continuous improvement. Control charting will improve managerial efforts to reduce the flow time of assets through the Base Processing Segment, and ultimately the depot-level reparable pipeline. Elimination of Assignable Causes of variation reduced average flow times by 31 percent. Identifying and eliminating Assignable Causes of variation will immediately improve process performance. The subsequent removal of Common Causes of variation will improve the process. Pipeline, Control charts, Reparable assets, Variation, Quality.
