dc.description.abstractThe United States Coast Guard continues to conduct major environmental and humanitarian response efforts in addition to the other mandated missions that must be performed. In 2009, the Coast Guard Surface Forces Logistics Center implemented a reliability engineering program in an effort to improve the availability of its aging surface fleet. This thesis is an exploratory analysis of the current status of the newly implemented reliability engineering program using Soft Systems Methodology (SSM) and statistical analysis techniques with the objective of determine how the shift to reliability-centered maintenance approaches and procedures has affected the availability of the medium endurance cutters, which have long been the workhorses of the modern Coast Guard. A key goal of this work is to determine what improvements can be made to the current reliability engineering program to enable the US Coast Guard to better achieve its mission. The SSM analysis discovered several key issues including procedures, personnel training, data mining, and data reporting. Further, the analysis led to examination of eight (8) years of cutter machinery failure data as a measure to transform cutter maintenance activities into constructive mission availability information using Goal Tree - Success Trees and Boolean logic. This preliminary analysis revealed lower than desired availability percentages and a decrease in cutter availability over time. The root causes for these results are examined and found to include program implementation issues, lack of proper training, a lack of adequate funding, the age of existing fleet assets, and the Coast Guard culture. Key research questions are answered and several key opportunities for improvement are identified. Several next steps or areas for future work are proposed. A more detailed analysis of the maintenance data could assist in improving the allocation of maintenance funding and logistics support. Additionally, analyzing the data by cutter operating location and associated maintenance costs could provide useful information regarding resource allocation. With the completion of these steps, the Coast Guard can adapt its program to fit the needs of the service.en_US
