Multi-Objective Optimization in the Conceptual Phase of Vehicle Development

This paper deals with the usage of multi-objective optimization techniques in the early stage of vehicle development. Integration of multi-objective optimization tools with vehicle dynamics simulation tools can provide significant improvements in the development process. Development of the optimization model, based on evolutionary algorithms, that is able to handle a large number of variables, constraints and objectives, and the usage of vehicle dynamics simulation tools, is a precondition for a complete solution for the conceptual phase of vehicle development. Some necessary steps lead to development of optimization models. These steps are identification of influence parameters, selection of criteria for the evaluation of vehicle dynamic characteristics and selection of optimization algorithms. Using a simulation eliminates the need for vehicle prototype in the early stage of development and reduces costs of development. Achieving optimum parameters of the vehicle at this stage of development reduces the possibility of wrong solutions or concepts.
