英文摘要：

For product layout design, abstracting it to a convex hull plus rubber band analogy layout pattern and establishing the optimization model is a innovative physics-based design method. This work expounded the critical technical problem and digital design technique of convex hull plus rubber band model design of 2D layout design from object-oriented program design method. That is, based on architectural structure of convex hull plus rubber band analogy layout pattern, establishment of object-oriented class model, generation of convex hull and rubber band, and rubber band analog design based on pitch time, etc. are represented, the critical technology of model digital design is resolved. This is an effective salution fror packing layout design model based on convex hull plus rubber band analogy.
