基于仿真的巡回式Chaku-Chaku生产线员工配置与产能分析

Modeling and simulation analysis for determining numbers of workers and output for Chaku-Chaku production lines of itineration style

为解决巡回式Chaku-Chaku生产线员工数量确定及产能计算问题,对Chaku-Chaku型双资源约束制造系统进行了研究,提出了指派员工数量的计算方法和生产线产能计算方法。建立了基于面向对象Petri网逻辑模型并形式化定义了Chaku-Chaku规则,通过仿真方法确认生产线稳态后系统的空间及物理层面特征,采用数值分析方法分析了同质员工与异质员工两种情况下生产系统的特性,确定了员工在生产线中的等待时间计算方法及产能计算方法。最后通过案例和仿真验证了计算方法的有效性,为企业应用该生产线提供了重要指导作用。

To solve the problem of determining the operator quantity and capacity for the Chaku-Chaku semi-automatic production lines,this paper studied the production lines constrained by dual resource,and proposed the method for determining the operator quantity and capacity.It built logical model based on colored timed Petri net and formalize defines Chaku-Chaku rules.It was confirmed the steady state of production lines from physical and space aspects by simulation system,studied the system features for the homogeneity staff and heterogeneous staff by the numerical analysis methods.Simultaneously,it worked out concrete calculation algorithm for waiting-time for operator and developed production capacity.Finally,based on the case and discussion of the simulation results,the case study shows that the algorithm is an effective approach to determining system operator quantity and capacity and very useful for the enterprise.
