摘要大规模定制一直是制造业面临的重大挑战。为此，柔性制造系统（FMS）通常被设计为适应变化并批量制造不同类型的产品，但产品使用传送带遵循单一的刚性路径，如果单台机器出现故障，整个生产线都会受到影响。然而，多产品动态生产系统可以在单台机器上长期故障的情况下运行。开发了一种针对多产品生产线的新颖动态建模方法，用于研究系统在机器故障和市场需求变化等随机干扰下的动态特性。多生产线的永久生产损失（PPL）和需求不满意被正式定义为实时性能指标。开发了一种实时分析方法来评估 PPL 和需求不满意程度。数值案例研究验证了实时多产品生产线模型的保真度和实时分析方法的有效性。
ABSTRACT Mass customization has been a major challenge in the manufacturing sector. For this purpose, Flexible Manufacturing Systems (FMS) are usually designed to accommodate variations and manufacture different types of products in batches, but the products follow a single rigid path using a conveyor and in case of a failure on a single machine, the whole production line is affected. However, a multi-product dynamic production system can operate under an elongated failure on a single machine. A novel dynamic modeling method for a multi-product production line is developed to investigate dynamic properties of the system under random disruptions such as machine failures and market demand changes. Permanent production loss (PPL) and demand dissatisfaction for multi-production lines are formally defined as real-time performance metrics. A real-time analysis method is developed to evaluate the PPL and demand dissatisfaction. Numerical case studies are presented to validate the fidelity of the real-time multi-product production line model and the effectiveness of the real-time analysis method.
