生产单元人机合作策略仿真分析

生产单元不仅要强调先进制造技术,还要重视高素质员工和灵活的人机合作方式,才能适应快速变化的制造环境。为动态、定量地研究生产单元的人机合作策略,结合计算机仿真和Agent建模技术,进行了基于Agent的生产单元人机合作策略仿真研究。建立人机合作仿真模型,提出人机合作仿真的实现方法;研究生产单元指定合作、部分自主合作和完全自主合作的合作机制;并以某发动机生产单元为例,设计了一系列仿真实验,通过比较任务等待时间、订单准时完成率、机器等待率和操作工利用率4个绩效指标,对该生产单元的各种人机分工模式进行了仿真分析和评价,从而指导实际生产单元采取更加合理的分工模式。

Simulation on human-machine cooperation strategy in production cells

To adapt to the rapid changes of manufacturing environment,production cell needs to focus on high qualified staff and flexible human-machine cooperation method at the same time,when advanced manufacturing technology(AMT) is emphasized on. In order to study human-machine cooperation strategy dynamically and quantitatively in production cells,a simulation study which combined computer simulation with agent modeling technology is carried out. Firstly,a human-computer cooperation simulation model is established,and its realization method is presented. Secondly,specific cooperation mechanisms of designated production cell cooperation,partly independent cooperation and completely independent cooperation are studied respectively. Finally,an engine production cell is taken as an example,a series of simulation experiments are designed,and four performance indicators of the task waiting time,order on time percentage,waiting rate of machine and operator utilization are established to analyze and evaluate all kinds of man-machine division modes of the production cell to find a more reasonable mode.
