Home | Overview | Solution Manager | Report Writer | Model Manager | A VORSIM Model

Model building operations are initiated from the VORSIM Model Builder control screen.  [Control Buttons] are automatically placed on workbook sheets as they are built. The bulk of model building work is done from the Equation Parameter workbook.

[Create a New Model] – This button begins the model building process by creating a definition workbook where model codes and other information are entered into a menu (new models can also be created by copying and modifying existing ones). [Load Definition Workbook] – Loads the model definition workbook. This workbook defines the model structure, creates variable names, and generates data and equation workbooks. [Load Data Workbook for Model] – Loads model data workbook for data entry. Data is kept in this workbook and automatically used for equation construction and model simulation. Utilities can ease the movement of data from spreadsheets to the data workbook. [Load Equation-Parameter Workbook for Model] – Loads equation workbook where equations are written, modified, and banked. The model workbook is created from the equation workbook. [Load Any File in Active Model Directory] – Brings up a menu of all files in the active model directory for loading. [Select Active Model] – Selects the active model for VORSIM operations from a set of saved models. Here the active model is named DEMO and is located in the directory C:\VMOD (name and directory in yellow cells). [QUIT] – Quits the VORSIM control screen and closes all open files (buttons with red lettering mean the current screen or file will be closed when the button is clicked). [Solution Manager], [Reports Writer], [Model Manager] – Switches to other control screens, closing the VORSIM control screen and any open files. [Model] – Closes VORSIM and brings up a menu of active models for selection for configuration and/or simulation.  Models also can be directly accessed from the VORSIM window. |VORSIM| menu: Each control screen shows the normal Excel menus and adds a VORSIM menu which activates programs especially useful to screen modeling or other activities. The |VORSIM| menu in the Model Builder control screen: From any definition or data sheet, numeric or text data can be saved and restored. All sheets in any workbook can be unprotected and protected. A data block can be copied from one sheet to other sheets in a workbook. This is especially useful for replicating changes in a workbook; a change in one sheet can be copied to other sheets. Any workbook can be backed up and a block of data from a backup can be copied to a current workbook. Short lists of equations can drawn up for printing or viewing. Finally, you can select which cell to display when a workbook is opened.
