在这一贡献中，提出了一种适用于轿车轮胎开发过程的结构设计概念。重点是一方面提供适当的多目标优化方法，使轮胎能够考虑在使用寿命期间应满足的多个要求，另一方面考虑到设计概念中的不确定性。由于在设计阶段考虑的一些结构参数是基于模糊、有限或不精确的信息来确定的，因此需要将它们建模为不确定的量。在这一贡献中，利用了不确定性模型的模糊性。在设计方法中考虑不确定性，除了优化目标函数外，还可以进行稳健性量化和优化。通过用基于神经网络的响应面近似代替昂贵的有限元轮胎分析，提高了计算效率。
In this contribution, a structural design concept, suitable for the application to passenger car tire development process is proposed. The focus is set on one hand on providing an appropriate multi-objective optimization approach, enabling the consideration of multiple requirements which a tire should satisfy during the operating life, and on the other hand on accounting for uncertainty within the design concept. Due to the fact, that some structural parameters, considered at design stage, are specified on the basis of vague, limited or imprecise information, it is required to model them as uncertain quantities. In this contribution, the uncertainty model fuzziness is utilized. The consideration of uncertainty in the design approach enables, beside the optimization of the objective functions, also robustness quantification and optimization. Numerical efficiency of the proposed methodology is increased through the substitution of the expensive FE tire analysis by a neural network based response surface approximation.
