Abstract : This report describes an application of ARMAN to the evaluation of electronics equipment maintainability. A comparative analysis of the effects of two different circuit technologies on the corrective Maintenance Task Cycle (MTC) is described. Circuit technologies represented are the hybrid vacuum tube-transistor type and the Integrated Circuit (IC) type. Vehicles for the comparison are the conventional circuitry F15A and the IC-based R45 airborne radars. The Inherent Corrective Maintenance Workload (ICMW) serves as the comparison denominator throughout the study. All possible component failures affecting each radar's Ground Mapping Mode were analyzed for corrective maintenance task sequences. Detailed MTC's and their performance times were synthesized by ARMAN for all failures. In addition, ARMAN was used to investigate the maintenance time effects of various design alternatives facilitated by the IC technology. The alternatives studied were four levels of R45 Built-In-Test (BIT) and four levels of R45 modularization. The study shows that the IC technology can contribute many significant improvements in equipment maintainability and that ARMAN is effective in evaluating them.
