Creating a Utility - Availability Tab Select Factory > Utilities. The overview window containing all the utilities defined in your model opens. Click New. A dialog box is displayed. Enter a unique code for the new utility. Click OK. The Utility Entry window is displayed. Click the Availability tab. If you want to set a default, enter it in the default available field. This would be used as the default for every time period involved but can be over-written. This saves time filling in every field for every line. If you want to change the availability of a utility during a time period, clear the use default column and enter the new time in the available column. Click OK to save your changes and close the window. Alternatively, continue populating tabs on this window. Related topics Overview Windows About Utilities
