In recent years, the Navy has begun to include |
|
reliability requirements in procurement specifications |
|
for wet-end sonar hardware. For the most part the |
|
requested reliability evaluations have focused on |
|
exponential modeling and the use of handbook methods |
|
originally developed primarily for electronics systems. |
|
In this report, we examine the relevance of this and |
|
other approaches. Reliability concepts are reviewed |
|
without restricting their scope to the description of a |
|
single class of operating behavior. The discussion begins |
|
with the indoctrination of the mathematical functions |
|
most commonly used in reliability descriptions. Modeling |
|
of the constant, increasing, and decreasing hazard rate |
|
situations is discussed. Reliability and service-life |
|
concepts are compared and contrasted from the prediction |
|
viewpoint. The task of demonstrating reliability in as- |
|
built equipment is also dealt with. The report calls |
|
attention to some of the special problems such as limited |
|
production and long intended life associated with |
|
evaluating sonar equipment reliability. It concludes with |
|
several recommendations directed toward the systematic |
|
improvement of sonar hardware. (Author) |
