工程设计中面向对象语义的实现

The Implementation of Object Oriented Semantic in Engineering Design

面向对象的方法的研究目前在基于产品的研究领域中是一个热点,该方法已经在产品设计与管理中得到一定的应用。但是由于在工程设计中各阶段对象情况比较复杂,不同阶段的对象不易进行统一的管理和相互转换,因此在工程设计环境中面向对象的语义的实现上有一定的难度。文章在产品参数化建模系统中成功的定义和实现了面向对象语义,采用装配关系对各阶段对象进行统一的管理,通过版本机制实现对对象的演化进行有效的管理,解决了一些将OO方法应用于工程设计环境中的技术难题。

Object Oriented method is a hotspot in field of product deslgn.It has been accepted widely in domain of product design and management.In different phases of Engineering Design,there is more complex instance.The objects in different phase are different and difficult to be managed effectively and transformed each other.Therefore,it is more difficulty to implement Object Oriented Semantic.In this paper,the Object Oriented Semantic has been implemented successfully in the product modeling system.The assembly relationship is used to manage the different object effectively. The version mechanism is used to implement object evolvement.So some technical difficult problems have been solved for OO method using in Engineering Design.
