Abstract：In order to realize the autonomy and diversity of interaction among product development activities, an interaction model of product development activities is constructed based on the cell interaction mechanism, which can support the management and optiminization of product development process. Firstly, the cell interaction mechanism is analyzed. Secondly, the function of cell membrane and input/output channels of the matter, energy and information are illustrated in detail. Thirdly, the cell interaction meta-model is established by using Petri net. Finally, the meta-model is validated in the design process of automobile fuel pumps.
