| Abstract: |
| It is very complex of the process of conceptual design of fixture, and the corresponding results are uncertain. The case based reasoning technique is a good method to solve this problem. This paper introduces the triangle function as the membership function to calculate the similarity based on the features and the fuzzy demand during the process of conceptual design of fixture. The similarity measurement model of fixture is set up and used in the case based reasoning, which simplify the process and improve the efficiency conceptual design of fixture. |
