In the previous research project "Tolerance management in early design stages", fundamental methods for early consideration of tolerances were developed. The results from the application of the individual approaches were linked with each other and with the conventional design process. Since the potential and applicability of these approaches strongly depend on the stored design and tolerance knowledge, the present project focuses not only on the further development of tolerance management methods but also on the specific provision of relevant data. For this purpose, robust design and tolerance management methods developed in the first phase of the project will be expanded and new ones are added in order to support the designer in the tolerance-compliant product development. The scientific challenge is the automation of the process in order to help to achieve reliable results independent of the user. The data management to be developed for this purpose allows consistent management of the product development information (from task classification to detail design) relevant to the tolerancing process. By defining rules (e.g. inferences in ontologies), relevant implicit knowledge can be used in early product development phases to automate the process. In this way, the methodology enables the tolerance concept to be verified even before the final product design without considerable additional effort. Due to the close link to the product development process this methodology improves the product design and thus contributes to avoiding costly iterations at the end of product development.

在先前的研究项目“早期设计阶段的公差管理”中，开发了早期考虑公差的基本方法。各个方法的应用结果相互关联，并与传统的设计过程相关联。由于这些方法的潜力和适用性在很大程度上取决于存储的设计和公差知识，本项目的重点不仅是进一步发展的公差管理方法，但也对相关数据的具体规定。为此，将扩展项目第一阶段开发的稳健设计和公差管理方法，并添加新方法，以支持设计师进行公差兼容产品开发。科学上的挑战是过程的自动化，以帮助实现独立于用户的可靠结果。为此目的开发的数据管理允许与公差过程相关的产品开发信息（从任务分类到详细设计）的一致性管理。通过定义规则（例如，本体中的推理），相关的隐含知识可以在早期产品开发阶段使用，以自动化过程。通过这种方式，该方法使得公差概念甚至可以在最终产品设计之前进行验证，而无需付出相当多的额外努力。由于与产品开发过程的密切联系，这种方法改进了产品设计，从而有助于避免在产品开发结束时进行成本高昂的迭代。
