Analysis of U.S. Air Force Administrative Lead Time for Procuring Aircraft Spare Parts
Abstract
This thesis describes the spare parts procurement process at Ogden ALC UT in terms of administrative lead time. Specifically, this research describes the process from MMILBB to either PMWFW or PMWFL. The process was described in three ways. A flow chart depicting the flow of paperwork and associated activity times was constructed. This was translated into a SLAM network diagram and then into SLAM computer code. The computer code was used to experiment with the procurement system by varying the activity times and branching probabilities. The important parameters were then used to construct a metamodel, an equation that describes the SLAM of the procurement syste. Within MM, the metamodel is sensitive to the percentage PF Forms 761 that need to be updated, to MIPR Control activity time, to the percentage of PRs going to PMWFW instead of PMWFL, and to the percentage of Prs under $100K going to PMWFW. Within PM, the metamodel is sensitive to activity time in PMWFW for Prs over $100K. Keywords: Administrative lead time; Simulation; Flow chanting; Computer Programs; Spare parts; Metamodel. (JHD)
