Operations for General Cartesian Multiplication of P/T Nets
Petri网的广义笛积运算

Two composition methods of Petri nets had been given in 1] i.e. addition and Cartesian multiplication of p/T nets. In this paper, some operations of general Cartesian multiplication for p/T nets are given. These operations preserve the structural properties of Petri nets. An example is given to show that it is useful for the composition and analysis of P/T nets.
