基于Witness的步进巡回式装配线建模与仿真分析

Modeling and simulation analysis on stepping walking worker assembly line with Witness

针对传统装配线和巡回式装配线在实际生产中的局限性,提出步进巡回式装配线的概念,并对其状态转移过程进行了分析,建立数学模型对状态转移进行描述;基于Witness离散系统仿真软件平台,建立传统装配线和步进巡回式装配线的仿真模型,在不同工况下进行模型的仿真运行,并根据仿真数据在生产效率、生产平顺性及生产均衡性等方面对二者进行了对比分析,总结步进巡回式装配线的最优运行规律,为实际应用过程提供理论指导。

Aiming at the limitation of traditional Assembly Line(AL) and Walking Worker (WW) assembly line in actual production,the concept of Stepping Walking Worker(SWW) Assembly Line(AL) was proposed.The state transition of SWW is analyzed,and a mathematical model was established to describe the state transition.Then based on Witness software system simulation software platform,simulation models of AL and SWW were established,and the two models ran with different working conditions.At last,the production efficiency,production smoothness,and production balancing were compared and analyzed between AL and SWW according to the simulation data.And these analysis summarized the operation rules of SWW,which may serve as a theoretical guide for practical application process.
