Timing Transaction Arrivals

There are some issues concerning timing of transaction arrivals at a component. Consider model fragment A in Figure 4.3.

Figure 4.3: Model Fragment A

Although transactions leaving the multiple-server will arrive at the Trigger and the Bucket at the same simulation time, the logic and behavior of each of these components will be executed in sequence. There is no guarantee which will occur first.

Figure 4.4: Model Fragment B

To guarantee that the Trigger "Server Off" executes before the transaction traverses to the Bucket, connect the components as in Figure 4.4.
