Design Advisor allows vehicle design decision makers to quickly and accurately examine material selection tradeoffs in terms of mass, cost and greenhouse gas emissions savings. It provides an easy-to-use simulation that allows users to enter vehicle design scenarios for quick evaluation. These material selection decisions are often made very early in the vehicle design cycle. Design Advisor is configured to operate in that context, the only required inputs being the information which would be available during the vehicle planning stage.  A sensitivity analysis is included to allow varying the input values to evaluate the robustness of the estimates.
