Inaccurate and Non- quantity Information for Qualitative Digital Prototyping

To solve the problem that inaccurate information and non-quantity information can not be used for quantitative simulation, the qualitative digital prototyping concept is developed by combining Kuipers qualitative sim-ulation theory with digital prototyping. The definition of qualitative digital prototyping is given with quaternion, and the conceptual framework of qualitative digital prototyping is established. According to the digital prototyping charac-teristics, the Prolog programming language and object- oriented knowledge representation method are selected to ex-pound the knowledge repersentation and system framework establishment of digital prototype system. The knowledge structure representation framework and structual model of qualitative digital prototyping are established, validated and simulated by qualitative simulation method. Finally, the feasibility of system simulation by digital prototype is verifi-cated through an example.
