Overview

The Undo Mining command is used to remove material from the schedule, and allows you to 'step back' to an earlierpoint in the schedule. It allows you to undo mining on all blocks or currently-selected blocks, and provides a choice ofperiod options. You can run this command at any point in the schedule to return to an earlier stage.

This exceeds the value displayed in the Check Schedule dialog, Difference column, for period 1.

For the PLANT FEED target for all 11 periods, text is displayed in red. This indicates that the Plant Feed targethas not been met for the destination "PLANT". The amount by which this target has been missed is shown in thDifference column - this value is taken from the mid point of the target.

Home > ISTS Tutorial > Scheduling > Updating the Schedule > Updating the Manual Schedule

Updating the ScheduleIn the following exercises, you are going to make use of the Update Schedule function.

This is a powerful facility that allows you to adjust your scheduling settings in the case of changes in production parameters.

For example you may wish to do this if a maintenance calendar is no longer valid (say, machinery maintenance downtime has been revised downwards due to a previous over-estimate of machinery failure), or you need to perform a revised schedule based on changes in the actual reserves measured from previous operations.

There are restrictions to updating your schedule, but this function allows you to perform a wide range of edits that will accommodate your real-world findings at any point in the existingschedule. Full control is granted over how existing periods are managed, allowing you to make the 'forward timeline' more accurate than simply proceeding with the original values. Youcan update your schedule by editing any (or all) of the following information categories:

Reserves : where new/updated reserve information exists, you can use this to drive the schedule moving forward in time.

Outlines : where geophysical boundaries are no longer in line with the original (baseline) shapes, you can update your schedule with new outline information. Note that theoutlines are a visual representation of the blocks being mined and edits to this file will not affect the reported scheduling values.

Calendars : update your schedule where calendar reporting structures have changed, or downtime is revised.

Destinations : you can change the capacity of the destinations in question (but note, you cannot change other 'rules' of the destination, such as material type)

Machines : you can continue your schedule based on edited machine settings and/or new fleet configurations

Trucks : New haulage parameters can be used to dictate the on-going schedule

Targets : Where new grade/tonnage targets are realised, you can use these to drive the schedule into the future

Scheduling parameters can change quickly and often, and the Update Schedule function makes it easy to perform an update at any time, allowing you to review the effect of thechanges on subsequent activities and undo (and re-do with new parameters) as often as you like.

In this exercise, you are going to update the schedule generated in the previous exercise by adjusting the maintenance calendar originally created in the Calendars exercise so that itreports in a different way (a different configuration of days, weeks and months). You will also change the capacity of the STOCKPILE 1 destination and review the impact of this on theon-going schedule before undoing it to continue the tutorial.

For more information on this facility, you can also consult your Studio 3 online help.

Updating the Calendar

Following on from the previous exercise, you are going to use the Update Schedule function to change the currently reported date configuration to a new arrangement. As set up inCalendars exercise, you are reporting against the following calendar:

You are going to change this to report against the following calendar:

1 . In the ISTS Task Pane , select Schedule Management | Update Schedule...

2. The Update Schedule dialog is displayed. In the Update group, enable the Calendars check box and click the associated ellipsis (...) button.3. The current calendar Time Periods are displayed as shown in the image above.

4. In this exercise, you are going to create a new calendar configuration (although you can simply update the original calendar if required for your needs). Click Clear to remove allcalendar entries from the table.

5. Change the schedule start date to begin 1 week from the current date (your new schedule will come into effect in 1 week's time). You do this by selecting the Start Date drop-down list to reveal a mini-calendar, e.g.:

6. Change the Number of Periods to '2' and click Generate . This will add two dates (schedule start date and schedule start date + 1) to the table below, e.g.:

7 . Change the Period Length TYPE (the drop-down list to the right of the Period Length field) and select [Week(s)], and click Generate .

8. Two more entries are added to the table representing two weeks additional scheduling:

9. Finally, two more time periods will be added, this time months. Change the Period Length TYPE to select [Month(s)] and click Generate .

Updating the STOCKPILE Destination Capacity

As this update also includes changes to the STOCKPILE 1 destination, the following exercise shows you how to update the Destinations information category prior to running anupdate.

1 . In the Update Schedule dialog, enable the Destinations check box and click the corresponding browse button.2 . In the Destinations dialog select the [STOCKPILE 1] destination and click Edit .

3. The Destinations: STOCKPILE 1 dialog is displayed - note that some of the settings here are not editable (when updating a schedule, you are restricted in how you can adjustdestinations. Click the Stockpile Settings button.

4 . In the Destinations: STOCKPILE 1: Stockpile Settings dialog, click the Supply tab. You are going to edit the settings to adjust the period in which material is scheduled to thestockpile (this is to accommodate the changes made to the calendar in the previous section).

5. Change the [Period 6 - #date#] entry using the drop-down list to change it to [Period 3 - #date#] - this ensures material will be delivered to the stockpile in Period 3, not 6, inorder to meet the specified targets. Click OK .

6 . In the Destinations: STOCKPILE 1 dialog , click OK.

7 . In the Destinations dialog, click OK.

8 . In the Clipping group, select the Keep All Activities option.

9 . Select the Schedule at earliest time option . The two settings above will ensure that all activities currently scheduled are pushed forward to meet the new timeline. For moreinformation on the other options, including how to clip activities in progress, consult your Studio 3 online help.

1 0. C lick Update . A CSV file will be generated and displayed containing a summary of the changes that have been made to the schedule - note that items that have not beenaltered by the new settings are not shown; only changed items are reported.

11. Close the CSV file.

Reviewing the Updated ScheduleThe schedule has now been updated; from the date specified, a new calendar will be used to determine the schedule and a new supply period has been set for the STOCKPILE 1destination. To see how this has impacted the previous schedule report, go through the following exercise:

1 . Leave the Update Schedule dialog displayed.

2 . Using the ISTS Task Pane , select Manual Scheduling | Act ivity Schedule .

3 . In the Act iv ity Sched ule dialog, select [Period 3 - #date#] using the Period drop-down list, if not already shown.

4. Select [LDR1] from the Machine Class drop-down list if not already selected. This will display the schedule activities for each period in their updated state. The values forPercent, Volume and Tonnes for activities 1-5 will be seen as follows (central section of table removed to reduce width):

Undoing t he Schedule Updates

After all that hard work, you're going to undo your update. The Undo function gives you a chance to 'test' new schedule parameters prior to an update, then revert the schedule back toits original state.

1 . In the Update Schedule dialog, click Undo .

2. The Act ivi ty Sc hedu le dialog will automatically update to revert your schedule to the pre-undo state, ready to continue this tutorial.

3 . Close the Act ivi ty Sch edul e dialog.4 . Close the Update Schedule dialog.

Note that any changes made since selecting Update will also be restored when the dialog is next used.
