Prophesy Screenshot

The screen shot was captured during an actual run and, except for the small purple box which was added with PhotoFinish to depict the message flow animation (the screen capture utility we used did not grab the moving boxes), the elements shown are true to the program. Shown on the screen are some of the main program features:

• The model shown is used to evaluate the workflow elapsed times and the load on a front end component receiving traffic from an IP based Wide Area network. The screen shows Prophesy’s ability to simulate the work generated by customers placing orders via phone to a data entry operator. i.e Prophesy is not limited to simulating network devices.
• The bars to the right of each icon indicate the resource utilization; the bars to the left indicate the queue utilization. Red color bars indicate loads over 60%, yellow bars indicate loads between 30-60%, and green indicates utilization below 30%. The color assignments are user customizable.
• The panel to the right shows the detailed utilization for resource FRONTEND. Also displayed is Prophesy’s histogram function showing how utilization varied during the simulation run.
• The panel below shows FRONTEND’s queue utilization. Notice that the FRONTEND label also contains the numbers 16:1. This indicates that we are simulating a situation with 16 front end devices (the network is highly loaded). The user can vary this number easily and play what-if scenarios.
• The panel at the bottom left is a Toolbox showing possible icon-based actions. The Toolbox allows more direct manipulation of the run by not requiring the use of the menu.
• The USA map in the background is a feature of Prophesy that allows placement of user defined BMP graphic files.
• The user can expedite or pause the simulation run by clicking on the VCR-like controls in the upper right of the screen.

Not shown in the screen shot is the Icon’s menu from which the user can drag additional icons to expand the network. Also not shown are many other result and input panels.
