Abstract : The paper attempts to standardize repair time predictions by introducing a new technique for making these estimations. This technique utilizes the predetermined motion time system Work-Factor and also Mento-factor which is a predetermined time system that estimates times necessary for mental activities. The repair time analysis was done by the Wofac Company, which developed both of these prediction systems. Experimental apparatus was designed to simulate a system with semi-automatic built-in test equipment. The experimental subjects used were completely unfamiliar with the equipment. They were required to simulate repairs by following a repair procedure in the accompanying maintenance manual for the system. The validity of the theoretical times was statistically determined by comparisons with the experimental times. This was done to verify the utilization of this new prediction technique in maintainability applications. (Author)
