摘　　要：满意优化能有效解决机械设计中的复杂优化问题。满意度函数的设计在满意优化中占有重要地位。本文针对问题的不同情况 ,提出了几种满意度函数的建立方法。对于满意优化在机械设计中的应用、满意度原理的进一步推广以及机械设计能力的提高具有一定的推动作用。In the application of the satisfactory optimization in mechanical engineering, the design of the satisfactory-degree is difficult and important. In this paper, two new methods—— the direct method based on the objective function, and the indirect method based on the search cost of the solution —— are presented for the design of the satisfactory degree. Fuzzy logic and artificial neural network are employed to implement these methods. It is helpful to the application of the satisfactory optimization to mechanical design, and the extension of the satisfactory degree theory.
