Abstract
Systems engineering practices in the Navy consider operational availability as a system attribute determined by system components and a maintenance concept. A better understanding of the risk attitudes of system operators and maintainers may be useful in understanding potential impacts to operational availability that the system operators and maintainers have. The method presented in this thesis synthesizes the concepts of reliability, risk attitudes, and utility theory to quantify the effect that risk attitudes of systems operators and maintainers have on system operational availability. The method consists of four main steps providing the engineer with a risk-attitude-adjusted insight into the system’s “utility” as determined by a system “value” parameter, which, in this case, is system reliability. This is accompanied by a final step that may be taken by systems engineers that uses the output of the previous four steps to inform any necessary iterations to the system design process. If it is deemed necessary to redesign the system (Step 5), the systems engineers will likely choose new system components and/or alter their configuration; however, redesign is not limited to physical alteration of the system. Several other options, which may be more practical depending the system's stage in the life cycle, address this issue from a maintainability or supportability perspective rather than a reliability perspective.
