【Abstract】 A product model was proposed to support creative design process with the ability of depicting the sta tic structure of product and the dynamic working process. The model is integrated with object oriented paradigm to implement encapsulation, abstract and hierarchical modeling of the product, particularly where the attribute value can be extended to manifold. And then the model employs Petri net to describe the dynamic working process of the product. The proposed model can be used to effectively support the creative design of product.更多还原
