Changing availability of resource numbers across time is normally handled with shift patterns. However there are other ways to change the numbers of resource across time. Visual Logic can give very detailed control, for example via the property Max Available. Resource Schedules allow a pattern to be described in a Simul8 Spreadsheet.
Check the Schedule Sheet check box in the Resource Dialog. Simul8 will request the name of a spreadsheet that contains a definition of the schedule.
The layout of the sheet is described by example inside Simul8. Simply select a blank spreadsheet the first time the feature is used and Simul8 will generate an example schedule that shows the appropriate layout of the schedule.
To view the schedule sheet after it has first been selected click RIGHT on the check box.
