摘　　要：提出一种支持产品创新设计的流形对象Petri网数据模型MOPN(Manifold Object Petri Net),其利用面向对象技术来刻画产品的静态结构,实现了产品数据的封装、抽象与层次化建模,特别是扩展了对象的属性类型,将对象的属性值扩展到流形上,因而可刻画对象属性值非均匀变化的情况。模型利用高级Petri网刻画产品的动态工作过程,不仅可支持产品工作过程的创新,而且还可通过模型的形式化来验证产品创新概念的逻辑正确性和完整性。Creative design includes a large number of design intents, design elements, materials, activities, in addition to a diversity of data types and complex relationships. The need to adopt appropriate product data model schemes and database technologies that can handle these complex cases continue to hinder the implementation of creative design for product. A new product data model called MOPN （Manifold Object Petri Net） is proposed to support for creative design with the ability of depicting the static structure and the dynamic working process of the product. The model is integrated with object-oriented paradigm to implement encapsulation, abstract and hierarchical modeling of the product, particularly where the attribute value of the product can be extended to manifold, and the high level petri net can be applied to describe the dynamic working process of the product. A prototype of a simulation tool with graphical interface has been implemented for this model.
