Man-hour is most important factor to evaluate the maintainability. Man-hour as in multiply repairing hours per case and number of repairers per case are depend on the difficulty and urgency of the recovering works, Thus, this paper tried to find die relationship between man-hour and effected factors to the maintainability by applies the MIL-HDBK472. The basic data used about 90000 cases statistical failure data from ships. According to the statistical data, man-hour approximated a Logarithmic Normal Distribution. And man-hour are effected on four primary factors. These factors are the difference of an installation systems, the difference of number of repairers, the difference a kind of ships and the difference of main engine outputs. Then, we made some equations to estimate man-hour using above four primary factors. Furthermore, we made some evaluation table to calculating the estimated MH based on human factors and circumstances factors. Finally, this estimated equations of maintainability characteristics are compared with the actual data from ships.
