Nowadays, RCM(Reliability Centered Maintenance), which means performing maintenance based on Reliability Analysis, is broadly applied to all over the industries. We also have seen an active utilization of big data in industries especially as advancements in big data processing technology is made. RCM and big data are also applicable to managing distribution facilities but are limited to fault resulted from deterioration only. However, as usage environment or usage level can cause different faults even from the same type of facilities, RCM must be performed in consideration of environmental factors to establish optimal maintenance plan. Currently, in case of domestic distribution facilities in Korea, there are issues to be resolved before applying RCM or big data such as maintenance and fault data system management, track record of environmental factors or more. This research studies the issues that must be settled in advance and the solutions to develop optimal distribution facility management system based on big data and RCM.
