The Visit Planner (click here to see the movie) is the tool that allows for the determination of the schedulability of the visits.

The Visit Planner cannot be run if the visit has not yet been processed in the Orbit Planner. Prior to submission, both the Orbit and Visit Planners will need to have been run on the entire proposal.

Before initiating the Visit Planner, select the visit or visits you wish to process; selecting the "Visits" container will process all visits in the proposal. Note that, to properly determine the schedulability of a visit, all visits that are linked to that visit (e.g. with a GROUP WITHIN) should be processed at the same time. Therefore, selecting one visit from a linked set will result in ALL linked visits being processed.

When the Visit Planner is initialized, all selected visits appear with a , which indicates that the display is out of date with what is in the proposal (similar to the red title of the Orbit Planner). If the visit has never been processed, the display states that schedulability of the visit has not yet been computed. Note that the there is a processing status line, which gives the status of the Visit Planner.

Processing the visit(s)

To process the visit, hit the Update Display button. Note that the processing status line states that the Visit Planner is computing schedulability. Like the Orbit Planner, there is a progress wheel to indicate the tool is processing, and the results are cached across sessions.When complete, the total visit schedulability is displayed. To examine the details of the constraints, open the key on the left of each visit. The Update Display button is now inactive - this indicates that the display is now up-to-date.

Each visit is labeled in the display, and placing your cursor on the label brings up a tool-tip giving the status (schedulable or unschedulable) and the mode (Phase I or II) the processing was performed in; placing your cursor in the timeline brings up a tool-tip which gives more details (schedulable or unschedulable, and the time range). You can also bring up a ruler by clicking anywhere in the display area. You can then drag the ruler to where you want (or just click in the display at the position of interest), and the box will display the Year/Day Number/Time of the ruler location. A Roll Range report is also available, which will be displayed both graphically and as a table.

A indicates the visit is schedulable. A visit which is schedulable can still have diagnostics (in the Tree Editor), while an unschedulable visit is indicated by a (and has no total visibility).

By opening the key on an unschedulable visit, you can see which constraint, or combination of constraints, is causing the visit to be unschedulable.
