针对生产线生产能力受行走工人效率差异影响的问题，以单元生产模式下的生产线为对象，提出了利用超越站运行超越机制的解决方案，并验证了其有效性;定义了超越机制下的多种运行规则，建立了包含超越机制的面向对象Petri网运行逻辑模型;通过数学分析，通过建立仿真平台，利用实测数据，研究了采用超越机制和不采用超越机制时系统产能、设备利用率和工时利用率的变化规律，为企业设置超越站提高竞走生产线产能提供理论指导。
Aiming at the problem that capacity of production line was affected by walking-workers'difference efficiency,by taking production line in cell production mode as object,a solution that using overtaking station to operate overtaking mechanism was proposed,and its effectiveness was verified.Multiple operating rules under overtaking mechanism was defined,and object-oriented Petri net operating logic model including overtaking mechanism was built.Through mathematics analysis,the production cycle saving with overtaking mechanism was calculated.The simulation platform was established to research the system variation of capacity,equipment utilization and worktime utilization under overtaking mechanism and non-overtaking mechanism by using measured data.The research provided theoretical guide on setting up overtaking station to improve walking-worker line capacity for enterprises.
