In order to quickly establish a customer specified PDM platform, the guidance of effective methods is
needed. In this paper, a function analysis model based on granular computing is proposed and is applied
to guide conceptual design of PDM platform in a medium-sized automotive enterprise. The obtained solution has been implemented and a customer specified PDM platform has been established which meets
the basic needs of this automotive enterprise well. This practical example is the initial application of this
model. In order to achieve the full application of this model, there are still many issues to be resolved. In
the follow-up study, the function representation based on granular computing will be discussed.
