Cost Savings by Establishing Life Limits

摘要

There is often a tendency in engineering to be overly cautious without due cause. This can be very expensive when establishing life limits on components of mechanical systems, whether repairable or not. When one considers military systems this may mean tax dollars into the scrap bucket prior to realizing the inherent life left in a part or system. This paper, discards the often used 'I feel good about this number' in favor, of a budget conscience and statistically accurate method to obtain the life limit from a given set of data and hence, lower system operating costs. The technique applied is known as the ENTROPY method and the results can be cost savings.
