A major portion of the Life Cycle Cost (LCC) of a modern high technology weapon system is determined by design decisions made very early in the development process. Many of these decisions affect the design so fundamentally that later changes become impractical. Although a computerized weapon system LCC methodology has been developed at Pratt & Whitney to evaluate engine trades, its complexity limits its usefulness during preliminary design when the largest number of decisions must be made. This paper describes a technique used to provide a simplified version of this methodology to design engineers to conduct configuration/cost/performance trades. By supplying the designer with a simple, effective evaluation tool, LCC becomes an integral part of the design system from the beginning.
