This study combines aspects of utility theory, probability theory, and mathematical programming to develop an efficient method for performing reliabilitymaintainability analysis during the early conceptual stages of system development. The general concepts of operational capability and system life cycle cost are used to construct an operational model for determining subsystem reliability and maintainability design point characteristics. Consideration of both technological and cost uncertainty is incorporated within the model. Specifically, the method developed provides a systematic and operationally efficient technique for selecting subsystem reliability maintainability alternatives when 1 attainable subsystem reliability maintainability levels are not known with certainty, 2 all life cycle element cost flows are not known with certainty, 3 chance-constraint restrictions exist on some or all of the following factors system availability, weight, reliabilty, maintainability, andor R and D cost, 4 some subsystem reliabilitymaintainability design alternatives are interdependent contingent andor mutually-exclusive, 5 the suitability of selecting any particular system combination of subsystem reliabilitymaintainability alternatives depends upon both cost and risk considerations.
