| 摘 要： | 考虑了工程多目标优化设计中存在的模糊不确定性，在物理规划的基础上，引入模糊物理规划概念，建立了模糊物理规划的数学模型，提出了模糊物理规划的求解方法。应用建立的理论和方法对模梁进行优化设计，并与不考虑模糊性时的计算结果进行了比较。实例分析表明，应用模糊物理规划所得到的计算结果更准确，更符合工程实际情况。

| Abstract: | In this paper fuzzy uncertainty of multi objective engineering optimization design is considered, and on the basis of Physical Programming, a mathematical model and the solving approach of Fuzzy Physical Programming are developed. Fuzzy Physical Programming is used in the design optimization of a beam, and the results are compared with that obtained without considering the fuzzy uncertainty. The example illustrates that Fuzzy Physical Programming developed in this paper can obtain more reasonable results, and they accord more perfectly with engineering facts. |
