【Abstract】 The structural properties of synchronization composition of Petri nets are deeply discussed. Some conditions of the structural property preservation by synchronization composition of Petri nets are obtained. It is shown that some structural properties are directly preserved by synchronization composition of Petri nets, but other structural properties are preserved under some conditions. These results are useful for studying synchronous composition of net systems.更多还原
