Early robustness evaluation considering the sensitivity of a product design to manufacturing induced geometry variation is a crucial basis for an efficient product development. In early design stages, this aspect is best implemented by a holistic quantitative robustness evaluation. However, despite the awareness regarding its great benefit, this aspect usually remains unconsidered in industrial practice. This is due to the missing structure of existing robust design approaches and the lack of necessary product information in early stages. Motivated by these current drawbacks the proposed research program addresses these issues through an integrated approach combining aspects of the design domain and the tolerancing domain. The approach is based on the contact and channel approach for structured analysis and documentation of embodiment function relations including boundary conditions and the tolerance graph enabling a computer-interpretable mapping of information relevant in the context of robust design. The approach fosters an explicit documentation of interrelations and a structured analysis. Thus, it enables a holistic robustness evaluation in early design stages.

考虑到产品设计对制造引起的几何变化的敏感性，早期的稳健性评估是有效产品开发的重要基础。在早期设计阶段，这方面最好通过整体量化健壮性评估来实现。然而，尽管人们意识到了它的巨大好处，但在工业实践中通常没有考虑到这一点。这是由于现有稳健设计方法的结构缺失，以及在早期阶段缺乏必要的产品信息。受当前这些缺陷的激励，拟议的研究方案通过结合设计领域和公差领域的各个方面的综合方法来解决这些问题。该方法基于接触和通道方法，用于实施例功能关系的结构化分析和记录，包括边界条件和公差图，使得能够对稳健设计环境中的相关信息进行计算机可解释的映射。这种方法促进了对相互关系的明确记录和结构化分析。因此，它能够在早期设计阶段进行全面的健壮性评估。
