Reliability prediction is the most basic task in performing integrated product support, and should be managed as a very important measure in terms of operating and maintaining. This paper conducted a reliability prediction in the military field for a commercial computer. As a result of calculating the failure rate using Windchill SW according to the reliability prediction procedure, it was 81.333194 failures/hours. In this case, MTBF was calculated at 12,295 hours during MTBF conversion using the failure rate. In addition, an impact analysis according to the operating environment and operating time was performed. Since the operating environment and operating time of the equipment are different when operating the equipment, it was confirmed that the MTBF was calculated differently even if the same equipment was operated.
