A target cascading method using model based simulation in early stage of vehicle development
Vehicle specifications which satisfy various constraint conditions of target performance indices are required in the early stage of vehicle development. For this decision making, model based simulation plays important role to provide candidates of feasible specifications and can be used to find optimal specifications by applying optimization method. In order to enhance the efficiency of later development processes, those optimal specifications obtained from the optimization problem are required to be not only feasible but also flexible. To guarantee these requirements, it is important for decision maker to understand feasible region space and its mechanism where satisfies every constraint based on model based simulations. The purpose of this study is not to find best solution in design space but to understand feasible design space and its mechanism.
