Comparison of the Air Force, Army, and Navy Test and Evaluation Reliability andMaintainability Data Base Systems

摘要

This study was conducted to create a single source document which could be usedby test and evaluation personnel involved in joint programs for translating reliability and maintainability terms. The comparison begins by describing the forms, data elements, and data items, as collected by the Air Force's System Effectiveness Data System, the Army's Reliability, Availability, Maintainability Logistics System, and the Navy's Maintenance and Material Management, Maintenance Data System. The Findings paragraph is a stand-alone document which could serve as a translating dictionary for reliability and maintainability data elements between the different service's data systems. Upon the conclusion of this study, several recommendations were made. 1. The Army should adopt the Work Unit Code structure of MIL-SPEC MIL-M-38769C. 2. The services need to agree upon the length of the Work Unit Code. 3. The services should establish a minimum set of collected data elements and items. 4. The services should publish an agreement on reliability, availability, and maintainability data elements and items for test and evaluation. Additionally it is noted that the major differences in data collection methodology is the Army's use of independent data collectors for improved data accuracy.
