The results of a study to define the significant factors which affect the feasibility of discard at-failure maintenance DAFM for USAF electronic equipment are presented. Included is a mathematical model which can be used to evaluate the total resource cost for DAF and repairable modules. To ensure model usability, a simple step-by-step procedure is presented which minimizes the requirement for complex mathematical manipulations. In addition to determining which is the more economical approach i.e., design for DAF or design for bit and piece repair, the model provides a means of defining the optimum DAF module size. Also included are discussions of recommended packaging techniques for DAF modules, the impact of microminiaturization on DAFM, and criteria for DAFM design.
