In this paper, the concept of packing optimization with shape morphing is introduced. The AAO formulation and bi-level formulation are studied and compared. By decomposing the original problem into system level and component level, the problem is simplified. For the system level global search, the GA could be used. For the system level local search and component level optimization, a gradient method may be used. Therefore the computational efficiency can be greatly improved. The convergence of the bi-level formulation for the complex system needs to be studied further. A parameterization-based morphing method and a mesh-based morphing method are implemented for comparison. The parametric-based morphing method is sufficient and applicable for most of the vehicle components. Mesh-based morphing has great morphing freedom and it is more suitable for components that can have any arbitrary shape such as fuel tank and various kinds of reservoirs. It is proposed that this kind of components should be morphed at a late stage of the configuration process to try to fill some available space. Therefore, how to find the available space in a given layout and efficiently morph the components to fit them in is an important issue to be investigated.
