摘要: 串行生产系统的可靠性和维护活动极大地影响系统产能、产品质量、生产成本和服务水平等关键绩效指标。为提高系统可靠性、增加产能、降低运维成本、保证产品质量和服务水平,提出一种考虑客户满意度的带缓冲串行生产系统维护建模方法。引入客户满意度模型量化客户对产品质量和生产时间的要求,考虑设备退化对产品质量的影响,建立基于设备状态的产品质量损失模型。采用质量维护阈值离散质量损失过程,结合机会维护理论制定系统维护策略。以最大化订单利润为目标,求解最优预防性维护阈值和质量维护阈值。最后,以某15工位汽车生产线为例,验证了所提方法的有效性及可行性。

关键词: 串行系统, 客户满意度, 维护决策, 缓冲, 质量损失

Abstract: The reliability and maintenance activities of serial production systems greatly affect key performance indicators such as system capacity, product quality, production costs, and service levels. To improve system reliability, raise production capacity, save operation and maintenance costs, and ensure product quality and service level, a novel maintenance policy considering customer satisfaction for buffered serial production systems is proposed. The customer satisfaction model is presented to quantify the customers' requirements for product quality and production time. The impact of equipment degradation on product quality is analyzed, and the quality loss model for products based on equipment states is established. Based on the threshold of quality for maintenance, the process of quality loss is discretized, and combining the theory of opportunity maintenance, the maintenance policy for the system is provided. By maximizing the order profit, the optimal preventive maintenance threshold and quality maintenance threshold are derived. Finally, an automotive production line consisting of 15 stations is taken as an example to show the effectiveness and feasibility of the proposed maintenance strategy.
