【Abstract】 Function modeling is a critical step in the conceptual design process.A Petri Net(PN) modeling technique for representation of function is presented based on the black box method and the elements which include flows,flow states and functions.The characteristics of function modeling are summarized.The feasibility of function modeling based on PNs is demonstrated.The functional model described in this work makes computer tools available that support functional design and innovative design in the future.更多还原
