| Summary: | Queueing models have been widely used to evaluate the performance of manufacturing systems. However, due to the trend of rapid growth in regards to the emergence of clustered machines in contemporary manufacturing systems, proper approximation for queueing models have to be derived in order to take the complex tool configurations into account.
In this paper, the performance of simple cascading machine; a single server with an input load port is being investigated. By assuming Poisson and Gamma arrivals with Gamma/Uniform distribution for load port and service time (M/G/1 and G/G/1), simulations are carried out to study the properties and behaviours of the queueing system. The research paper started off by addressing the verification of the queueing model. Through these simulations, the variation of queue time with several factors such as inter-arrival time, mean load port and service time and variability are evaluated. This paper also proposes several possibilities for future development in this field. |
