Object-oriented undirected graph model in P&ID design system

  • When developing P&ID aided design system, the logical topology information between entities needed to be represented. In order to avoid the complexity of importing additional abstract entities, a new model is designed in which the logical topology information is united to the primary entity's data structure. This model has been successfully practised. The modeling process of P&ID undirected graph model from piping network graph was presented. After analyzing the characters of P&ID undirected graph, it points out what should be paid attention to when applying the model and how to extend the undirected graph.
