Abstract: Decomposition of Petri nets is an important approach to analyze the properties of complex net systems. With the decomposition method of Petri nets by defining an index function on the transition set, a net system can be decomposed into a set of T-nets. The properties of original net are provided by obtaining the properties of the de-composition subnets and the property preservation between the original net and the subnets. A determination condition for the liveness of the original net system is provided. The obtained results offer an effective way for property analysis of some structure- complex Petri nets.

Key words: decomposition of Petri net, indexes of transitions, property analysis
