| Abstract | This thesis studies the effect of various factors on the performance of the CONWIP/push and DEWIP/push production control systems. The experiments are performed using simulation model of a hypothetical flexible manufacturing flow shop. In this thesis, the simulation models are developed using Sigma software. The developed models are used to evaluate the performances of those two hybrid systems under the exponential processing times. The initial buffer sizes are estimated using queuing formula. The simulation model is then used to determine suitable buffer sizes to meet the demand target. The performance of the CONWIP/push and DEWIP/push production control systems are compared with the identical environment. The results from the experiments of this hypothetical manufacturing system show that the total output and the average workload of CONWIP/push system are better than DEWIP/push system. However, the standard deviation of the DEWIP/push system is better than CONWIP/push system. |
