Abstract: In order to realize the modularity design of the body-in-white (BIW) at the concept stage, a method for module identification and selection is proposed. Based on considering manufacturing costs and assembly costs, a modified graph-partitioning algorithm is used to optimally divide the vehicle body assembly structure into a set of components, which also means, modules. In the next moment, sort the order of the molds by differing cost values, then define and divide three different kinds of modular from the BIW structure:Kernel module, parameterized module and flexible module. After applying the platform constraints, the performance differences of a car build on a platform or not should not be evident, otherwise, a dynamic regulation should be adjusted in accordance with the difference. In the example, the result of the module identification and selection proves the effectiveness of this method.
