摘要
针对产品个性化定制过程中装配工时不确定、装配车间动态扰动频发问题,提出基于数字孪生的实时装配工时车间调度模型.构建基于数字孪生的装配车间调度整体架构,利用射频识别(Radio Frequency Identification,RFID)技术实时采集物理装配车间的工时数据,用改进的Rete算法进行实时装配工时处理.建立基于实时装配工时的装配车间调度数学模型,采用改进的人工鱼群−禁忌算法对模型求解,以实现实时装配工时车间的调度优化.实证结果表明,模型算法进行实时装配工时车间调度具有一定的可行性及优越性.
Based on digital twin,a real-time assembly man-hours workshop scheduling model was proposed,considering the uncertainty of assembly man-hours in the process of product customization and frequent dynamic disturbances in the assembly workshop.The overall architecture of assembly workshop scheduling based on digital twin was constructed.Radio frequency identification(RFID)technology was used to collect real-time working hours data of physical assembly workshops,and the real-time assembly working hours were processed by using the improved Rete algorithm.A mathematical model of assembly workshop scheduling based on real-time assembly man-hours was established,and an improved artificial fish swarm-taboo algorithm was used to solve the model,so as to realize the scheduling optimization of the real-time assembly man-hours workshop.The empirical result shows that the model algorithm has certain feasibility and superiority in realtime assembly man-hours workshop scheduling.
