  • Enter the equipment unavailability

To specify requirements and wishes regarding the use of equipment, you can enter unavailability and/or wishes. Unavailability (red) should be reserved for mandatory cases (when staff cannot be scheduled during that time slot). For all other cases (where it would be preferable for staff to be or not be scheduled during that time slot), enter optional unavailability (orange) or wishes (green).

1. Distinguish between unavailability, optional unavailability, and wishes

Unavailability (red)

Unavailability (red) should be reserved for essential cases, when the equipment cannot be used during a time slot. 
For example, if a vehicle cannot be used on Mondays, you mark all Monday time slots as unavailable.

Optional unavailability (orange)

Unavailability (orange) is used to indicate time slots during which it would be preferable that equipment is not used. During automatic placement, optional unavailability is treated by EDT as unavailability until you decide to ignore it in order to resolve course in failure.

For example, if it's best not to use the laptops on Friday afternoons, click and drag the orange paintbrush on the Friday afternoon time slots.

 

Note
When you decide to ignore optional unavailability to resolve courses in failure, the optional unavailability of all the equipment is temporarily ignored. Therefore, do not enter mandatory requirements as optional unavailability.

Wishes (green)

Preferences allow you to specify the time slots during which it would be preferable for equipment to be used. During automatic placement, EDT tries to take these into account, but they are by no means guaranteed, unlike unavailability or time constraints.

For example, if certain machines should be used primarily in the morning, click and drag the green paintbrush on all the mornings.

2. Enter a equipment's unavailability or wish

  1. Go to the display Timetable > Equipment > Unavailability, wishes and constraints and select the equipment.
  2. On the right-hand panel, above the time grid, make sure the correct paintbrush (red, orange, or green) is selected and that the frequency is correct (Weekly, or Weeks F1/Weeks F2 if the unavailability or wish only applies every other week).
  3. If courses have already been planned, they appear with the icon [icone].
  4. Click and drag the paintbrush over the time grid to paint the time slots concerned by unavailability or the wish.

3. Delete an unavailability or a wish for equipment

To delete an unavailability or a wish, select the paintbrush of the same color and click and drag over the painted area.

4. Enter an unavailability or a wish for a multi-selection of equipment

If several pieces of equipment have the same unavailability, you can enter them in a single operation. To do this, select all the concerned equipment before clicking and dragging the red paintbrush on the grid.
For example, you want the computer equipment to never be in use on Monday mornings.
