Model management tasks are accessed from the Model Manager control screen.  Equation matrices can be banked, restored, or edited.  Models can be modified, expanded or shrunk.  Model workbooks can be archived, backed up, or restored. Model files made with earlier version of VORSIM can be updated and modified to operate with VORSIM 15 in Excel 2013.  Model files can be archived in a special archive folder.  Operations formerly in a menu have been transferred to a tool button.

[Put All Equations into Bank], [Restore All Equations from Bank] – Equation banking programs; all model equations (matrices) can be put into, or taken out of, an equation bank.

[Add Sheets/Variables to Expand Model] – Expand the active model with more sheets, categories, and/or variables.  A new definition workbook is created and the model can be rebuilt with the additions.

[Change Base Period], [Add Another Time Period] – Change base period and expand the ending time period.

[Remove Variables to Shrink Model] – Remove variables that are not needed in a model; and then rebuild a smaller model from a new definition workbook...

[Restore Backup Data to Data Workbook] – Restore data from a backup data workbook to a newly created data workbook, putting old data into the correct place in the new workbook.  Whenever model workbooks are rebuilt, they can be filled with backup data.

[Backup a Single File] – Backup a selected file (workbook).

[Load Any Workbook] – Load any workbook in the active model directory.

[Replace Key Workbooks with Backups] – Restore key workbooks (definition, equation, data, and indicator) for model from backups.

[List Files in Model Directory by Type] – Prepare a form listing all model files by type (same as button in Report Writer).

[Backup All Key Files] – Backup key workbooks, all equation matrices, and cells from data and definition workbook.  This button backs up all necessary files associated with a model. These backups can then be used as data sources for rebuilt model workbooks.

[Edit Banked Equation Matrices – Add/Delete Equation Terms] – Edit banked equations, add/remove equation terms and change parameter matrices (parameter values for equations).  Also, Armington elasticity formulas can be created automatically here from elasticities of demand and substitution.

[UG – Model Manager] – Load Model Manager part of User’s Guide.

[Model Manager Tools-A] – Accesses a mix of tools: add documentation to models, summarize location of variables, create summaries of workbooks or sheets, and other miscellaneous tools.  The first three buttons deal with options for labeling and documenting models.  One button summarizes the content of a workbook. Others deal with another way of summarizing workbook contents.  If you create a new workbook, you can restore text comments from a backup file.  Finally, it is useful to create a summary of equations – this option shows the equation generation matrix column heads along with a sample equations generated.  This gives you a quick way to check on, and look at how your equation terms fit together.

[Model Manager-B] – This form includes some conversion and other programs, including one to list all models saved in the VMOD folder.  The conversion program changes suffix labels on model files to follow the Excel 2013 format.

[Modify Links in Workbooks] – This form provides a systematic way to changes links in model files (created elsewhere or under an earlier version of VORSIM) to those required in VORSIM 15.
