Evaluate the Performance of a Hybrid Manufacturing System Using GI/G/1 Network
Abstract—This paper proposes an Queueing network to investigate the impact of a hybrid manufacturing system. The hybrid manufacturing system is a new conceptual manufacturing system that contains multiple channels that are analogous to cells of CM but where each channel resembles a JS configuration. Moreover, each channel contains the required machine types but fewer machines of each type than JS. Also, each product will always be processed in the same channel in terms of no inter-channel movements in MCM system. There are two objectives for this research. The first objective is to develop queueing approximations of flow time and WIP level for the hybrid system. In particular, GI/G/c approximations are developed using open queueing network in this research. The second objective is to evaluate the impact of the key factors on the performance of the hybrid system. By changing the value of the key factors in the approximations, the insights for the system performance can be realized. Through analytical models, different factors are analyzed and a suitable manufacturing system design with the combination of the factors is identified.
