Methodology highly iterative design production

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.

增加个性化和高市场不确定性迫使公司不断使客户参与产品开发，并考虑到晚期开发阶段的产品变化。物理产品的高度迭代发展为应对这些挑战提供了巨大的潜力。但是，这也导致对生产技术（技术计划）平行计划的新需求。在物理产品的高度迭代开发过程开始时，对产品的要求几乎是未知的，导致有关产品属性和功能的不确定信息。在开发过程的过程中，这种信息不确定性正在不断减少。为了使技术规划人员能够将其计划和评估方法调整到现有信息不确定性方面，必须对其进行适当量化。此外，在高度迭代的开发过程中，预计将有望进行频繁和深远的产品变化，这在短时间内的生产技术规划中必须考虑并预期。由于在高度迭代的开发过程中经常生产原型，因此还需要进行系统的评估和用于此目的的制造技术。必须考虑到开发过程的何时使用序列技术作为原型生产是有意义的，以确保在早期阶段最小化过程不确定性。根据目前的研究状态，一种支持技术计划者在高度迭代的物理产品中的生产过程序列中支持的方法尚不存在。拟议的研究项目的基本目标是调查高度迭代产品开发项目中变化的框架条件之间的相互关系，并进行了优化的过程序列设计。为此，正在开发一种方法，该方法支持技术规划师在原型和系列生产的过程序列设计中，以高度迭代的物理产品开发。该方法允许技术规划人员在每个迭代循环中就需要用于所需原型的制造技术做出决定。此外，考虑到开发过程中产品设计的频繁变化，应该可以在开发过程中设计过程序列。因此，该方法首次允许在高度迭代的开发过程的背景下为过程序列推导一般适用的设计规则。
