Prepare for the simulation
To make the model ready for simulation, we’ll specify general project information and the
duration of the simulation run. Since we’re just testing our first-cut model, we’ll perform
a short, 20-day run.
1. Open the Project Parameters dialog box by using the Run > Setup menu item and
clicking the Project Parameters tab. In the Project Title field, type Mortgage
Review Analysis; we’ll leave the Statistics Collection check boxes as the
defaults, with Entities, Queues, Resources, and Processes checked and also check the
costing box.
2. Next, click the Replication Parameters tab within the same Run Setup dialog box. In
the Replication Length field, type 20; and in the Time Units field directly to the right
of Replication Length, select days from the drop-down list. Click OK to close the
dialog box.
Save the simulation model
Now that you’ve done some work on your model, it seems like a good time to save it.
Click Save on the Standard toolbar or select the File > Save menu item. Arena will
prompt you for a destination folder and file name. Browse to the target folder in which
you want to save the model (e.g., C:\My Documents) and type a name (e.g., Mortgage
Review) in the file name field.
Arena’s model files store all of the model definition, including the flowchart, other graph-
ics you’ve drawn, and the module data you entered. When you perform a simulation run,
the results are stored in a database using the same name as the model file.
Simulate the process
With these few, short steps, we are ready to predict the future! The mortgage application
model contains all of the information needed to run the simulation.
Start the simulation run by clicking the Go button or clicking the Run > Go menu item.
Arena first will check to determine whether you’ve defined a valid model, then will
launch the simulation.
