Click on the run button below to start the simulation. This applet represents a smaller Facility than was used for our project, with only nine (not 81) exits. When you press the Run button a set of 18 packages (two for each of the nine exits) will be created in a random destination order and sorted. If you pause the simulation you can see the boxes are marked with their destination.
Results are shown in the text area once the simulation has finished. Destinations are represented by the primary sort number and the secondary sort number destination (which primary runout they came off of followed by how far down that secondary sort they are). For example, 11 is the exit closest to the input. Press the Reset button and then the Run button to start a new sort.
