| Abstract: | A solution method is proposed for the problem that it is difficult to obtain the global optimal solution in the early stage of vehicle development, including multi-system co-simulation, multi-objective optimization and comprehensive evaluation. The vehicle thermal management system is studied by applying this method. Based on Dymola and Isight, the 1D multi-discipline co-simulation is carried out and Pareto solution set is obtained. Then the analytic hierarchy process (AHP) and weighted score are used to comprehensively evaluate the Pareto solution set, and the global optimal solution is obtained. Under the constraint conditions, compared with the basic solution, the comprehensive score increased by 27.3% . |
