Factors Underlying Recent Trends in the Operational Availability of Shipboard Equipment (Material Support Study).

摘要

This is a study of trends in the operational availability of shipboard equipment and factors underlying these trends. Using 3-M data, the study found decreasing operational availability for all three kinds of equipment analyzed. The main components of operational availability, reliability and mean downtime, were examined to determine which was responsible for the decrease. The finding that mean downtime was the main reason, for electronic and HM/E (hull, mechanical, and electrical) equipment, led to an investigation of the trends in deferred maintenance actions, supply times, and administrative delay times.
