利用模糊数学中的择近原则,以容差-成本模型为基础,通过引入模糊数学中的隶属度函数和贴近度原则,结合实验并设计方法提出了一种模糊容差稳健优化设计方法,较好地解决了多目标容差设计的全局最优问题.最后通过一个实例验证了该方法的合理、有效性.
Based on the tolerance-cost model and by introducing the membership function and closeness principle in fuzzy mathematics, a method of fuzzy tolerance robust optimization is proposed based on the principle of proximity, which is based on the tolerance-cost model. The global optimization problem of multi-objective tolerance design is well solved.Finally, an example is given to verify the method’s validity and effectiveness.
