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.
