【Abstract】 This paper elaborated the function basis used to functional modeling, and described a functional model based on a function basis and a representation of meta-function and function object, then present the modeling framework of the conceptual design including meta-function layer, function object layer, behavior layer and behavior relation layer which could be conveniently used to product conceptual design. There is an example used to illuminate the functional model and conceptual design model in this paper.更多还原
