An Improved Method for Evaluating Torpedo′s Working Reliability in Sea Trial

Aiming at the limitation in evaluating torpedo′s working reliability only by success/failure type or index number type, an improved method for objectively and accurately evaluating torpedo’s working reliability in sea trial via combination of the two types is proposed. The evaluation result is a comprehensive one concerning test sample size, total voyage time, task time, fault number of success/failure type and index number type, etc. The variation of reliability level with task time is more significantly influenced by the fault of index number type than by the fault of success/failure type. The evaluation result of the proposed method is more objective and accurate than the conventional ones.
