基于图形转换的构件组装研究与应用

Padberg J,Ehrig H等使用代数规格语义的Petri,基于图形转换理论提出一种通用构件组装框架,该框架可以适用于不同领域的动态和静态的构件组装.但由于其限制连接件的输入接口是互不相交的,即割裂了与传统Petri网的同步合成和共享合成的联系,也限制了其实际应用的灵活性.给出一种较弱的唯一性条件,及基于该条件的结构唯一性和内容兼容性的证明,并讨论在此框架体系中融合传统Petri网综合方法.最后将该框架体系实际应用于联锁逻辑的描述.

Research and Application of Component Composition Based on Graph Transformation

A Generic framework of component composition with algebraic Petri nets,which was presented by Padberg J and Ehrig H on the basis of the graph transformation rule,provides a powerful support for dynamic and static component assembly in different fields.However,this framework is not flexible enough in practice due to the disjunction among import interfaces in each reduction step.The framework is extended by presenting a unique condition of composition.Based on the condition,the structure uniqueness and content compatibleness are proved,and the conventional synthesis of Petri nets in this framework is also discussed.Finally,the interlocking logic based on this framework is illustrated.
