Abstract:

Analytical models, which consider maintenance ratio as an independent variable when establishing system support requirements, are developed. The prime objective in developing these models is to minimize the total data requirement for implementation, and allow for a meaningful implementation at early stages of system development. System characteristics of availability and availability x reliability identified as an inherent effectiveness are treated from both a costed and uncosted point of view. Cost considerations consists essentially of development and support costs. For the costed models, cost ratios of fixed to variable costs are identified. Optimum system availability, reliability, mission, time, MTTR, and MTBF are identified for all values of the developed cost ratio parameter which is a function of the four basic types of costs identified.
