A RELIABILITY-MAINTAINABILITY TRADE-OFF PROCEDURE FOR NAVY ELECTRONIC EQUIPMENT,
Abstract
The development of a reliability-maintainability trade-off procedure for electronic systems and equipment is presented. The procedure constitutes an analytical design tool for systematically gen erating and evaluating design approaches for reliability and maintainability, and for select ing a design which: (1) satisfies a specified availability goal (or an alternative goal such as dependability); (2) satisfies design and mission related constraints; and (3) results in design optimization with respect to a trade-off cri terion such as minimum cost. The procedure is oriented to the task of assisting design initia tion as opposed to design review in accordance with the requirement to make major design deci sions during the planning stage or in the early phases of the design and development cycle. The concept of a ''standard design'' or starting point design assumption, and a well defined method of considering alternative design ap proaches facilitate the use of the procedure as a design initiation tool. Although the procedure can be applied in its present form, its use will be greatly simplified by the development of im proved restore time and failure rate prediction techniques, the collection of a body of standard design and support data, and refinement of the procedure itself though application.
