| 摘 要： | 专家系统的核心问题是要使计算机具有一定的形象思维能力,而专家的“经验”又不便直接表达为数值,更不便直接进行经验的推断,而用模糊数学有可能成为总结归纳技术经验的一种重要手段。本文讨论如何把模糊数学用于机翼结构型式的评定,协助设计人员作出有关机翼结构型式选择的决策。

| Abstract: | The conception of CAD (Computer Aided Design) is briefly discussed.Moreover, the application of expert system and fuzzy sets theory to CAD is described.Two examples of choosing structural type of airplane wings are given in this paper to illustrate the method discussed here.A degree of "satisfaction" for index of structural weight and cost is expressed by a value of the membership function of fuzzy sets.The membership functions embody experiences of experts.The results of the two examples are satisfactory. |
