In most Visum applications you create a model of supply (the network) and demand for an area of investigation. Then you develop several variants of the initial situation and various scenarios. The variants are then compared and evaluated based on calculation results. Thereby numerous files (including and excluding calculation results) are created for the individual variants. You can use the Compare networks function to organize the file contents, making sure that information is only saved to one storage location (Comparing and transferring networks). This allows you to reduce data maintenance when changing your model. In Visum, scenario management takes care of maintaining all your files.
It provides the following benefits:
- Visum saves all project files in a standard folder structure.
- Visum provides a clear project overview, showing all variants of your model. When you enter a meaningful name for a variant and its parts, your entry is not limited by any file system specifications.
- To edit a variant, use it in calculations or for analyzing results, simply open it by entering its name in the project view (you will not have to search for it in the Windows file system).
- When you perform calculations or comparisons across all variants, scenario management spares you many manual steps and automatically merges the calculation results of several variants. You can easily adopt the results in form of a comparison table into your project report.
- In the Multi-user mode, multiple users can build up scenarios simultaneously.
