The model in Figure 9.16 accomplishes this batch service. In this model the multiple-server is set to the batch size and the Server On compound component turns the server on if it is empty and there are 10 or more transactions in the FIFOQueue. The Trigger labeled "Server Off" turns the server off when each transaction leaves service. When a server is off all transactions currently in service complete normally, but the server will not send out messages for additional transactions. As a result, service on all transactions in process will complete, but additional arrivals to the system will queue until there are at least 10 and the server is empty.
Notice the LinePlot labeled "Server Utilization." It shows the number of transactions in service over time. It demonstrates graphically the batch service and independent nature of the service completions.
