ABSTRACT

We consider the question of how stability in automotive manufacturing systems should be analysed. This topic is motivated by the need of original equipment manufacturers to evaluate the performance of their production system to ensure efficiency and long-term competitiveness. In order to deal with the increasing complexity of the manufacturing process, original equipment manufacturers need to focus on efficiency in the manufacturing process and supply chain. Since stability is one determining factor of efficiency they need to implement indicators to quantify and visualise stability. While the overall target for the long-, mid- and short-term planning processes remain the same, the application of and specifications for performance measures differ. We present, analyse and evaluate different indicators and reveal their capability to represent the status of stabilised production facilities. We also describe the challenges that arise when implementing these performance measures in real-world production facilities and give recommendations on how to manage these challenges. We provide a framework to assign indicators to planning problems. The transparency provided by accurately chosen indicators fosters understanding of the overall performance of the system and enhances the management of stabilised production.

摘要

我们考虑应该如何分析汽车制造系统的稳定性的问题。本主题的动机是原始设备制造商需要评估其生产系统的性能，以确保效率和长期竞争力。为了应对日益复杂的制造过程，原始设备制造商需要关注制造过程和供应链的效率。由于稳定性是效率的决定因素之一，因此他们需要实施指标来量化和可视化稳定性。虽然长期、中期和短期规划过程的总体目标保持不变，但绩效衡量的应用和规范有所不同。我们提出，分析和评估不同的指标，并揭示它们代表稳定生产设施状态的能力。我们还描述了在实际生产设施中实施这些性能措施时出现的挑战，并就如何应对这些挑战提出建议。我们提供了一个框架来为规划问题分配指标。准确选择的指标提供的透明度有助于了解系统的整体性能并加强稳定生产的管理。
