The objective of this project is to examine the feasibility of developing an ibm pc cost estimating model for determining the economic impact of incorporating emerging technologies into new weapon systems/subsystems during Premilestone I planning. The technology areas of interest to be examined are; advanced avionics, high-performance turbine engines and high-temperature materials. The effort to be accomplished during Phase I will include; developing a "functional requirements analysis" philosophy, designing an emerging technologies database, designing a data collection mechanism, defining a "regressive learning curve" theory and defining cost estimating concepts. The planned cost impacts concepts will encompass not only the direct costs but also the interoperational (i.e. industrial base, military and commercial infrastructures, logistics, training) costs associated with the incorporating new technologies into weapon systems.
