Use the Average Waiting Time program to determine a reasonable number of queues to use if there are 1000 customers and:

a) The inner-arrival time is 5 and the service time is 5

b) The inner-arrival time is 1 and the service time is 5

c) The inner-arrival time ranges from 0 to 20, and the service time ranges from 20 to 100

d) The inner-arrival time ranges from 0 to 2, and the service time ranges from 20 to 100

AWT model

public class GlassQueue extends ArrayUnbndQueue

public class ArrayUnbndQueue implements UnboundedQueueInterface

public interface UnboundedQueueInterface extends QueueInterface

{

void enqueue(T element);

//Adds element to the rear of this quee.

}

public interface QueueInterface

{

T dequeue() throws QueueUnderflowException;

//Throws QueueUnderflowException if this queue is empty;

//otherwise, removes front element from this queue and returns it

boolean isEmpty();

//Returns true if this queue is empty; otherwise, return false

}

description of the AWT model

description of the assignment based on:

Identify which of the authors' classes used for their Average Waiting Time (AWT) model is responsible for each of the seven items identified in #42.

Use the AWT model to determine a reasonable number of queues needed to serve a thousand customers, under four different scenarios specified in #43.

Modify the AWT model to:

report out the largest number of customers enqueued at the same time

assign the next arriving customer to a specific queue based on shortest finish time

provide a user interface control to allow user to select shortest finish time or shortest queue for assignments
