Abstract

ABSTRACTThis article presents a general account of the work of the Bureau of Ships in applying analytical statistical methods to problems in Naval engineering. An attempt is made to give a clear idea of the specific contribution of the statistical methodology in each of the various applications described. To this end, the statistical background is discussed at some length, both in the main body of the paper and in an Appendix. It is brought out in the discussion that the type of statistical methodology which has been most useful is the type in which the emphasis is not so much on the mere gathering of relevant data, as on the processing and interpreting of the data in such a way that probable inferences can be drawn from them through the use of the modern mathematical theory of statistics. The applications comprise studies of the engineering performance of the fleet, research in and development of materials used in shipbuilding and maintenance, and control of quality of purchased materials. Particular attention is paid to the establishing and enforcement of standards by statistical methods. The article concludes with emphasis on the fact that the statistical methodology is only a tool of the engineer, albeit at times an indispensable one, and is no substitute for sound engineering theory.
