Abstract:

Headquarters Air Force Materiel Command AFMCLG tasked the AFLMA to determine which method quarterly 7WS transactions or daily DAC transactions more accurately records and reports reparable item failure data. AFMC receives DAC images on a daily basis and 7WS images on a quarterly basis. At this time, AFMC uses data obtained from DAC images to compute worldwide requirements computation. Data on 7WS images is compared to data contained on DAC images. Thus far, AFMC personnel have noted a big difference both and - in the number of failures reported for reparable items on DAC images when compared to 7WS images. We analyzed 7WS and DAC data from 10 bases for the period 1 Jul - 30 Sep 99. When we compared data on each bases repair cycle record to data on 7WS images we found that 99.99 percent of 7WS images are direct reflections of failure data contained on the repair cycle record. When we compared DAC failure numbers to 7WS failure numbers we identified differences similar to those found by AFMC. We discovered several reasons for the difference in numbers reported by the two methods, all of which could be attributed to DAC images. The bottom line is buy and repair requirements are both under and over estimated when DAC data is used for worldwide requirements computation. The 7WS image is more accurate. Therefore, we recommend using 7WS images as the source of failure data for worldwide requirements computation. We propose come changes to the 7WS images as the source of failure data for worldwide requirements computation. We propose some changes to the 7WS process to make it even more accurate, and when these changes are completed, to eliminate the DAC process.
