A SIMULATION STUDY ON TELEPHONE REMANUFACTURING PROCESSES

This paper focuses on modeling and simulation of two real telephone remanufacturing processes with the objective of improving the system throughput. We start with the system description and then build the corresponding simulation models. A series of s imulation experiments are done with different values for the model parameters and the results show that they are close to reality. In particular, the bottleneck processes are the same as those of the real systems. Using the simulation results, a method to improve the system throughput is proposed by adding more workstations to the bottlenecks. Also, we extend the basic simulation models to include multiple telephone types. Comparisons of dispatching rules are performed using the extended models and the result shows that the suggested rules are much better than the existing one.
