摘　　要：在近些年的制造环境中,由于市场对多品种、小批量定制产品需求的增加,生产制造更加深入地向着柔性方向发展.如何利用现有资源,提高生产效率,实时地对系统性能进行评估与预测,并对基于小批量生产的实时调度进行优化改进,在分布式柔性生产系统中具有重要的研究意义.因此,基于退化机器模型的多批次串行生产线的性能进行分析,并对分布式生产系统进行任务调度及预测性维护.具体地说,对于具有退化机器模型及有限容量缓冲区的生产系统,首先采用马尔科夫分析方法建立数学模型;随后,提出精确方法来计算此生产系统模型实时的性能指标,并针对该模型下的调度问题,设计最优完成时间指标优化算法;此外,提出基于退化机器模型的预测性维护策略以减少完成时间;最后,通过数值实验验证该算法的可行性和有效性.In the modern manufacturing environment,the production systems develop towards a flexible direction due to the increasing of the market demands of multiple varieties and small batch-based customized products.In order to make better use of existing resources and improve production efficiency,real-time performance evaluation and prediction of real-time scheduling and optimization improvement based on small batch production have important research significance in distributed flexible production systems.This paper mainly studies the performance analysis of multi-batch serial production lines based on degenerate machines,and carries out task scheduling and predictive maintenance for the distributed production system.Specifically,for the production system with the degenerate machine model and the finite capacity buffer,the mathematical model is established using the Markov method firstly.Then,an accurate method is proposed to calculate the real-time performance indexes of the system based on the model,and an algorithm is designed to optimize the completion time index for the scheduling problem under the model.In addition,a predictive maintenance strategy is proposed to reduce the completion time for machines with degradation models.Finally,the feasibility and effectiveness of the mathematical model and algorithm are illustrated by numerical experiments.
