摘要
本文介绍了工程设计中的不确定性信息，着重讨论了轻型飞机在总体设计阶段中，对总体性能进行模糊优化设计的必要性．对蜜蜂１１号修改型飞机的总体性能参数建立了多目标模糊优化模型，并运用普遍型模糊规划的方法加以求解．优化的结果表明，蜜蜂号飞机优化后的总体性能有较大的改善，得到了更满意的飞机设计方案．本文的实践说明，如果能适当地运用模糊优化技术，会使工程设计与决策更现实、更合理．
Uncertainty information which exists in engineering design is introduced. In particular, the importance of fuzzy optimization in the preliminary design phase of light aircraft is discussed. The system performance of MFll-M light aircraft, such as takeoff. level-flight. stalling. speed. etc, is considered to found the model of multi-objective fuzzy optimization. Then the method of general fuzzy programming is used to solve this optimization problem in computer. The results obtained after optimization show that the system performance of this plane is modified to a very satisfactory .solution.
