... · guide the technology teams in their research and development efforts and assure that all assumed metrics are opti~nized to Me overall vehicle requirements · provide the Vehicle Engineering Team with a mean.c to make tradeoff studies between contender subsystems and components and to determine the minimum acceptable performance parameters for competing technologies objectively optimize selected subsystems and systems to meet performance requirements with minimum fuel consumption The PNGV org~nwation concluded at a USCARJgovernment modeling conference in November 1994 that the system analysis tools available are inadequate for the PNGV challenge. It was decided that a qualified contractor, capable of performing systems analysis and modeling was a vital requirement.

... The Technical Roadmap, in Section IIIA, clearly states: The role of systems analysis in He PNGV is to support component, systems, and vehicle development by providing the analytical capability to efficiently and accurately assess competing technologies, and vehicle concepts against Goal 3 objectives and vehicle performance requirements. This will enable an objective evaluation of risk, benefit, and cost, in order to focus on the best options, win Be least expenditure of resources.

... Within the PNGV there does not appear to be complete awareness of the composite state of the art of the competing technologies, nor are the best models and simulation codes for these technologies available. In Be committee's view, there is a clear need for focused, central leadership to coordinate the technical teams and address overall vehicle requirements.

... Recommendation. Overall vehicle system and subsystem analysis driving component developments should be under the control of a USCAR technical director.
