查询词典 labeled graph

In general,given two vertices V and W in a graph,it is not always possible to find a path connecting them（see Fig.3-9）;such a path will exist only when the graph is"in one piece".

一般而言，给定图的两个顶点V和W并非总能找到连接它们的路（如图3-9所示）；只有图"在一块之中"时，这样的路才存在。

One is by knowledge Petri net First AND/OR graph was evolved by calculating cut set of relationship Matrix of parts which shows the assembly relation between the parts. Then the KPN was generated with AND/OR graph automatically. Running the KPN, an optimum assembly sequences was obtained last. The other is by Hopfield neural network.

一是利用知识PETRI网对装配过程进行建模，并自动规划出最佳装配序列的方法；这种方法首先根据产品装配的关联图，利用割集计算，自动生成产品装配的与/或图，由产品装配的与/或图转化成知识PETRI网，然后，运行此知识PETRI网，便可得产品的最佳装配序列。
