Profile: A Technique for Projecting Maintenance Performance from Design Characteristics.
Abstract
The report describes PROFILE, a computer-aided technique for assessing the maintainability of a system, based upon a specification of the system's design. For each fault of interest, PROFILE generates a sequence of actions required to isolate and correct the malfunction, and it determines the time to perform the generated procedure by accessing a data bank of standard times for generic maintenance actions. The projections are sensitive to design characteristics which determine what actions must be performed to isolate and rectify the fault, and to factors which affect the time to perform those actions. A PROFILE analysis of a representative sampel of failures yields a distribution of maintenance times and actions performed, to aid decision making throughout the design cycle. The projections of maintenance actions also are of potential value in assessing training requirements. Two experiments, using different electronic systems and technician populations, were conducted to obtain detailed corrective maintenance data. The corrective maintenance performances predicted by the model correspond well with the observed performances. (Author)
