项目摘要

Increasing individualization and high market uncertainties force companies to continuously involve their customers in the product development and to take into account product changes even in late development phases. The highly iterative development of physical products offers great potential to meet these challenges. However, it also leads to new demands regarding the parallel planning of production technologies (technology planning). At the beginning of the highly iterative development process of physical products, the requirements to the product are often almost unknown, resulting in uncertain information regarding product properties and features. In the course of the development process, this information uncertainty is continuously diminishing. In order for technology planners to be able to adapt their planning and evaluation methods to the existing information uncertainty in terms of application effort, it must be quantified appropriately. In addition, frequent and far-reaching product changes are to be expected during the highly iterative development process, which must be taken into account and anticipated in the planning of production technologies in a short period of time. Due to the frequent production of prototypes in the highly iterative development process, a systematic evaluation and selection of the manufacturing technologies to be used for this purpose is also required. It must be taken into account at what point in the development process the use of serial technologies for prototype production makes sense, in order to ensure that process uncertainties are minimized at an early stage. According to the current state of research, a methodology that supports technology planners in the design of production process sequences in highly iterative development projects for physical products does not yet exist.The basic objective of the proposed research project is to investigate the interrelationships between the changed framework conditions in highly iterative product development projects and an optimized process sequence design. To this end, a methodology is being developed that supports technology planners in the design of process sequences for prototype and series production in the highly iterative development of physical products. The methodology allows technology planners to make a decision in each iteration loop regarding the manufacturing technologies to be used for the required prototypes. In addition, it should be possible to design the process sequences during development for subsequent series production, taking into account the frequent changes in product design during the development process. Thus, for the first time, the methodology allows the derivation of generally applicable design rules for process sequences in the context of highly iterative development processes.

越来越多的个性化和高度的市场不确定性迫使公司不断地让客户参与产品开发，并考虑产品的变化，即使在开发的后期阶段也是如此。实体产品的高度迭代开发为应对这些挑战提供了巨大的潜力。然而，这也导致了对生产技术的并行规划(技术规划)的新需求。在物理产品高度迭代的开发过程开始时，对产品的需求通常几乎是未知的，导致关于产品属性和特性的不确定信息。在发展过程中，这种信息不确定性正在不断减少。为了使技术规划者能够使他们的规划和评估方法适应现有的应用努力方面的信息不确定性，必须对其进行适当的量化。此外，在高度迭代的开发过程中，预计会出现频繁和影响深远的产品变化，这在短时间内的生产技术规划中必须得到考虑和预期。由于在高度迭代的开发过程中经常生产原型，还需要对用于此目的的制造技术进行系统评估和选择。必须考虑到在开发过程的什么时候使用系列技术进行原型生产是有意义的，以确保在早期阶段将工艺的不确定性降至最低。根据目前的研究现状，目前还没有一种支持工艺规划者在实体产品高迭代开发项目中设计生产工艺序列的方法，该研究项目的基本目标是研究高迭代产品开发项目中改变的框架条件与优化的工艺序列设计之间的相互关系。为此，正在制定一种方法，支持技术规划者设计实物产品高度迭代开发中的原型和系列化生产的工艺序列。该方法允许技术规划者在每个迭代循环中就用于所需原型的制造技术做出决定。此外，考虑到产品设计在开发过程中的频繁变化，应能够在开发过程中为后续系列生产设计工艺序列。因此，该方法第一次允许在高度迭代的开发过程的背景下推导出过程序列的一般适用的设计规则。
