In the overall digital computer reliability estimates the repairability factors such as the detection, removal, and prevention of failures must be included in the analysis. These in turn do not depend on the computer system organization above, but also on the capability of the maintenance personnel. The design of a computer system with a specific repairability figure is difficult since the statistical data for the new system is not available a priori. The authors make an attempt to correlate certain experience gained during the operation of a Ural-2 computer with the repairability design parameters for inclusion in future designs. Thus, the computer availability time is related to the mean restorability time which in turn is shown to depend on a number of factors computer functional organization i.e. whether provisions are made for executing test programs, amount of equipment redundancy and built in control circuitry, location of fault indicators, structural organization i.e. whether the structure is modular and access to measuring and test equipment is easy, organization of maintenance routines and schedules, and the qualification of maintenance personnel.
