The Idagon Models


 

(for Windows Computers)
 

The Short Run Model (48 months)
 

The windows version is a 532 KB Stella File. It was constructed with Stella Ver 5.1.1 and tested on an IBM ThinkPad with a 12" screen using Windows 95. The Winzip program was used to compress the file to 155 KB. Unzip the file and open the model. The Idagon model is much larger than the other models in the book, so you'll notice a longer delay as the model (and the sketch) is loaded. Your opening screen should appear as shown on page 383 of the book. Try a simulation with default values for the weights and reservoir policies, and check your "score." The score keeper should give you 144 points for the simulation.

The Long Run Model (480 months)
 

The windows version of the long run model is a 544 KB Stella File. It was constructed with Stella Ver 5.1.1 and tested on an IBM ThinkPad with a 12" screen using Windows 95. The interface was designed to fit on the small screen by asking for print set up in the landscape mode. The Winzip program was used to compress the file to 159 KB. Unzip the file and open the model. The opening screen will be similar to the short run model. The addition will be a new button to take you to controls on land development and efficiency of irrigation. The simulations will run for 480 months rather than 48 months.
