Bottleneck Information and Reduction: An analysis of the Logistics Reparable Pipeline

摘要

This article presents the analysis of select avionics line replaceable units (LRUs) from the F-l6 weapon system and centers on depot sourced Not Mission Capable Supply (NMCS) parts shipments. Lateral supply support was not considered in the analysis. The goal was to identify the specific location of bottlenecks within the logistics reparable pipeline (LRP) and offer recommendations that may reduce or eliminate them. A total of 768 NMCS, DD Form 1348-lA Issue Release- Receipt Documents (IRRD), were retrieved from the Enhanced Transportation Automated Data System (ETADS). Analysis identified 641 shipments that exceeded the allowable Uniform Material Movement and Is sue Priority System (UMMIPS) time standard. This is an 83.45 percent failure rate. Focusing on F- 16 avionics LRUs was not by chance. The top five problem parts, according to the then PACER LEAN project office, were selected for this study.' PACER LEAN, at the time was Headquarters Air Force Materiel Command's (HQ AFMC) test program to verify whether the Depot Repair Enhancement Process and Contract Repair Enhancement Program were working as planned. Problem parts are defined as those parts shipments that continually exceed UMMIPS standards. UMMIPS standards are used throughout the DoD and are set forth in DoD 4140. 1-R. UMMIPS recognizes the priorities used by both transportation and supply.
