摘要: 针对具有自动装卸搬运机器人的制造单元,着重考虑其双重资源约束的特点,提出了该系统的有限缓冲开排队网的建模方法。根据工件的加工、装卸与搬运等工艺流程,定义该系统的排队网模型的各种状态,基于连续时间马尔可夫链,采用精确解法对该模型进行分析求解,获得系统一系列的稳态性能指标。为了验证排队网建模方法的有效性,建立其对应的仿真模型,分别采用排队网模型的数值计算与仿真模型的仿真统计2种方法求出系统的性能指标进行对比,并基于排队网模型对该制造单元的系统性能进行分析,为该类制造单元的资源配置优化和设施布局优化等问题提供重要的理论支撑。

Abstract: Focused on a manufacturing cell with an automatic loading/unloading and transporting robot, considering dual resource constrained in particular, an open queuing network model with finite buffer capacity was put forward. Firstly, according to the processing, loading and unloading, transporting of the workpiece, each kinds of state about the queuing network model of the intelligent manufacturing cell is defined. Secondly, based on Continuous-time Markov Chain, this model is solved by exact solution method, and a series of the steady-state performance of the system is obtained. Thirdly, in order to verify the validity of the queuing network modeling method, the corresponding simulation model is established. Finally, the system performance is solved and comparing the two methods which are the numerical calculation in the queuing network model and the simulation statistics in the simulation model, the system performance of this manufacturing cell is analyzed based on the queuing network model. This research can provide important theoretical support for the capacity configuration optimization and facility layout optimization of this kind of the manufacturing cell.

Key words: dual resource constrained, queuing network, continuous-time Markov chain, system performance
