Abstract: Stochastic network technology was applied in concurrent product development process modeling. The information prerelease model and the degree of concurrence definition were presented, and the stochastic network planning method was put forward to support concurrent product development. Thus, the corresponding simulation method was proposed. Based on the definition of eigenvalue, such as degree of concurrence, degree of time overlapping and degree of information coupling, the degree of concurrence of the whole product development process could be calculated accordingly. An example of product development process calculation was provided to illustrate the validity of this method.
