DEVELOPMENT OF CRITERIA AND QUANTITATIVE PREDICTORS OF MAINTAINABILITY OF AIR FORCE EQUIPMENT
Abstract
A technique was developed for measuring and predicting the maintainability of Air Force equipment. The criteria chosen, after analysis of the concept of maintainability, are active unscheduled maintenance time (the mean number of man-hours spent in actual unscheduled maintenance per maintenance action) and active unscheduled maintenance load (the mean number of man-hours spent in actual unscheduled maintenance per system operating hour). A technique was developed and predictions based on the technique were compared with skilled mechanics' estimates of the time required to perform a sample of F-106 maintenance actions. The results agreed quite well. The technique requires considerable work from systems analysts and maintenance engineers, and it does not provide many quantitative relations between the criteria and equipment characteristics. However, it promises to aid in design and technical order preparation, and it imposes no new data requirements. (Author)
