技术链的优化通常是作为每个单独工艺步骤的局部问题进行的。然而,要在产品特性方面优化技术链,局部优化是不够的,必须采取更全面的方法。现有的方法考虑了一个零件的制造历史,通常伴随着高水平的研究工作。本文提出了一种系统的方法,将制造历史集成到技术链优化过程中,与现有的基于模拟和实验的方法相比,工作量大大减少。根据以前的方法和模型,确定了一组代表性变量来描述技术链内的交互和依赖关系。此外,开发了一种由三个步骤组成的方法,该方法允许可视化以及解释技术链内的因果关系。利用该方法推导出了两种不同的技术链优化策略。第一种策略通过调整指定的参数来实现全局优化,而不会改变技术链中的流程。而第二种战略包括重新设计整个链条。
The optimization of technology chains is usually conducted as a local problem of each individual process step. However, in order to optimize the technology chain in terms of product properties a local optimization is insufficient and a more holistic approach is indispensable. Existing methods, which consider the manufacturing history of a workpiece, are often accompanied by a high level of effort in research. This paper presents a systematic approach to integrate the manufacturing history into the technology chain optimization process going along with a significant reduction of effort compared to existing methods based on simulation and experiments. Resulting from previous methods and models a set of representative variables is identified to describe interactions and dependencies within technology chains. Furthermore, an approach consisting of three steps is developed which allows a visualization as well as an explanation of the cause-and-effect relationships within technology chains. This approach is used to deduce two different optimization strategies for technology chains. The first strategy allows a global optimization by adjusting specified parameters without changing the processes within the technology chain. Whereas the second strategy comprises a redesign of the whole chain.
