Order and Ship Time Computation for Stocked Local Purchase Items.
Abstract
The current Air Force method for computing the Order and Ship Time (O and ST) for Local Purchase (LP) items is to determine an overall average for all requisitions not exceeding 175 percent of the Uniform Material Movement and Issue Priority System (UMMIPS) standard. With data collected from nine Air Force bases, three analyses were conducted; the result of which indicated that the currently computed O and ST average does not provide an accurate O and ST on which to base stock leveling decisions. The first analysis indicated that there were three factors affecting O and ST: the method of procurement, commodity group of the item, and the characteristics of the individual item. These factors were then used to develop alternative computational models for O and ST. The second analysis compared these models to determine which model provided the most accurate O and ST forecast. A final analysis was then conducted on the effect of the truncated O and ST values exceeding 175 percent of the UMMIPS standards. Conclusion and recommendations were drawn from the analysis of alternative computational models and the analysis of the 175 percent truncation policy. (Author)
