The original design of the berth system was optimized and the 9 optimal schemes were ob?tained by applying the process of DFSS. The relationship of the berth heat insulation and heat-insula?tion factor was studied by parameter design method. The benchmark and vehicle test results show the poor insulation of original design is improved, and system weight is reduced by 30%.
