The Initial Replacement Rates INREP project sought to identify sources of failurereplacementengineering data which could possibly be used to supplement existing Navy sources of initial replacement rate data. Data generated by the Government-Industry Data Exchange Program GIDEP and the Reliability Analysis Center RAC were identified as the most likely candidates. GIDEP and RAC data were compared with existing initial replacement rate data and with operational data to evaluate the range of coverage and the quality of the rates. The primary conclusion is that the range of coverage of the GIDEP and RAC data is much smaller than the range of coverage of the existing initial replacement rate data and that neither the GIDEP nor the RAC data compare more accurately with operational data than the existing initial replacement rate data. Therefore, the GIDEP or RAC data bases are not needed by the Navy for initial provisioning unless the existing initial replacement rate data do not include data for a particular item. Author
