Abstract : The report develops the concepts of reliability, maintainability and availability, and emphasizes application to shipboard machinery of new design. A specific objective of study has been to arrive at methods for quantitatively specifying and predicting shipboard machinery utilization characteristics such as service life, capability to operate for given time intervals without failure, and maintainability. These methods were required to be practical, and amenable to quantitative numerical computation. A charcteristic of shipboard machinery, and of machinery in general, is the non-experimental failure behavior of the parts. This contrasts strongly with the generally accepted exponential behavior of electronic parts. Because of this nonexponential behavior, new approaches are necessary for predicting, specifying and measuring a machine's reliability, maintainability and availability. For non-exponential probabilities, the mathematical description decomes complex. An objective of this study has therefore been to reduce the difficult mathematics to a straightforward engineering technique suitable both for manual arithmetical computation and for computer evaluation.
