Batch Arrivals II

Another variant on batch arrivals has batch size as a random variable. A simple extension to the previous model provides this alternative.

Figure 9.8: Batch Arrivals

Figure 9.8 shows two components added to the model of Figure 9.7: a Modifier labeled "capacity" and a Trigger labeled "Set Capacity.". The capacity Modifier samples a uniform random variable on the interval [0,30] and sets it in the capacity attribute on the transaction in the Arrival Process. The Set Capacity Trigger then sets the capacity of the Batch Source Sampler to that value. Then, the Start Trigger starts the Batch Source arrivals as before.

Compare the LinePlot labeled "Number in the Queue" in this model to the previous example. Here, in addition to the timing of the discrete jumps in queue length, the size of the discrete jumps in queue length is random.
