The run configuration tool allows you to store a set of instructions that can be used to run a model multiple time.
There are often cases where a user will have a set of runs they need to do. Before the run configuration tool, the user would have to use a command script (DSS only), or run the model multiple times to re-create the runs. The run configuration tool allows you to store these configurations, and run all/some of the configurations with a single click.
The simulate tool on the main Vensim toolbar now has a drop down button beside it, if you click this, the option to display the run configuration manager will be displayed.
