In this paper, we present a semi-open queuing network modeling approach to estimate performance measures of a manufacturing system. It is assumed that the arrival rate of the product and the service rates of the various servers are available. The manufacturing system is assumed to have a fixed number of pallets. A job arriving into the system first enters the system's job queue. If there is a pallet available in the pallet pool, the job enters the network of servers immediately, along with the pallet. Otherwise, it waits in the job queue until a pallet becomes available. When a job exits the system, the pallet associated with the job returns to the pallet pool. The semi-open network is a more realistic model of a manufacturing system because it estimates the time an arriving job waits to be paired with a pallet. Experimental results are provided to demonstrate the effectiveness of the approach.
