Abstract :

We are facing a knowledge economy and digital era. What is the process of an engineering design? It can be understood as the designer under the design requirements â�?�?to make a series of decision under uncertain design environmentâ�? in order â�?�?to do the right designâ�?; â�?�?to do the design rightâ�? as well as â�?�?to get the design right implementationâ�?. The designer needs to go through system analysis; i.e., to review past design alternatives in their mind (experiences) and make a comparison among them for satisfying design requirements; â�?�?To do the right designâ�?. Secondly, â�?�?To do the right designâ�? is guaranteed by engineering rules and specification as the design constraints and the third one â�?�?To get the design right implementationâ�? means the design should be well treated through acceptability to the related stakeholders. The intelligent design methodology needs to follow designerâ�?�?s intelligence during design processes through simulation by artificial intelligence technology, among them, first of all is the designerâ�?�?s fuzzy reasoning processes of comparing his past design samples (experience) in their mind with the assigned design requirements. According to above statements, the available Computer Aided Design (CAD) nowadays is no longer CAD, but CAG, for there will have no design parameters from the fuzzy reasoning by computer, but the heuristic considerations from the designer and input to the drawing machine for the engineering drawing. As the emergence of digital era, characterized by â�?�?Softening of theoryâ�? and â�?�?Hardening of the experienceâ�?, the theorem are going more and more softened by uncertain mathematics such as fuzzy logic for accommodating to the changeable environment; on the contract, the experiences are going more and more hardened and stored in computer as the knowledge base. It provides the theoretical basis and possibility of realizing intelligent CAD (as we prefer to ICAD), a conclusion can be made that Fuzzy-AI model is suitable for intelligent design.
