1) Re-recognize the design process.
The development of intelligent design system depends on the understanding of the design process itself. Although people have made a lot of explorations in design methods, design procedures and design rules, from the perspective of computerization, the current design methodology is far from meeting the needs of the development of design technology, and it is still necessary to explore design theories and design patterns suitable for computer processing.
2) Design knowledge representation
The design process is a very complicated process, involving the application of many different types of knowledge, so a single knowledge representation is not enough to effectively express all kinds of design knowledge. How to establish an effective knowledge representation model and effective knowledge representation has always been the key to the success of designing an expert system.
3) Multi-expert system cooperation technology
A complex design process can generally be divided into several links, each of which corresponds to an expert system, and multiple expert systems work together and share information. Fuzzy evaluation and artificial neural network are used to effectively solve the multidisciplinary and multi-objective decision-making and optimization problems in the design process.
4) Redesign and self-learning mechanism.
When the design results can't meet the requirements, the system should be able to return to the corresponding level for redesign to complete the local and global redesign tasks. At the same time, we can use inductive reasoning and analogical reasoning to acquire new knowledge, sum up experience, constantly expand the knowledge base, and realize self-improvement through re-learning.
5) Comprehensive application of various reasoning mechanisms.
In the intelligent design system, besides deductive reasoning, it should also include inductive reasoning, analogy reasoning based on examples and various fuzzy logic reasoning methods based on incomplete knowledge. Comprehensive application of the above reasoning methods can learn from each other's strong points and better realize the intelligence of the design system.
6) Intelligent man-machine interface
Good man-machine interface is very necessary for intelligent design system. For complex design tasks and some decision-making activities in the design process, with the participation of design experts, better design results can be obtained, thus giving full play to the respective strengths of people and computers.
Intelligent design refers to the application of modern information technology, the use of computers to simulate human thinking activities, improve the level of computer intelligence, so that computers can better undertake various complex tasks in the design process, and become an important auxiliary tool for designers.
