Scheduling in iGantt
Auto-Scheduling Module
iGantt's Auto-Scheduling module allows you to automatically schedule activities on resources in order to maximize resource utilization. This is achieved through the auto-scheduling module's ability to intelligently select activities and activity rates according to targets or priorities.
- For underground you first use geometry-based auto-precedence generation to automatically create precedences for adjacent development strings. Secondly, you assign equipment or crews to development activities. Next, you set the maximum aggregate rate of a jumbo or development crew. Then you specify the maximum rate on a single heading. You can choose stoppable or unstoppable activities. Stoppable activities may have delays inserted as a higher priority activity becomes available during scheduling. Finally, you start the Auto-Scheduling procedure to automatically generate a balanced schedule.
- For open-cut operations the procedure is similar. You would allocate specific shovels to respective mining areas, generate precedences, and initiate auto-scheduling.
The auto-scheduling module is ideal for medium to long term scheduling.
Edit Activities On The Fly
To have smooth equipment utilization, or to ramp up production on a new project or expansion you can use the material movement constraints. This lets you constrain the minimum and/or maximum total material movement for any time period. If you wish to be more specific and drop down to the level of material movement from individual locations or resources, it is simply a matter of typing in minimum and/or maximum movements for individual locations in given time periods. This enables you to force scheduling from certain locations at certain times or to prevent scheduling in certain locations.
Click And Drag Precedences
With iGantt, adding precedences to your activites is as simple as clicking and dragging. You can also add both forward and backward precedences, or add delays between the end of one activity and the beginning of the next.
Self-Updating Categories
The activity chart is able to display certain categories of information regarding your activites, including duration and quantity values. These automatically update as you alter your activites, giving you a real-time indication of just how your changes affect your schedule upstream and downstream.
Easy To Use Activity Grouping Display
Displaying your activities in certain groups is easy to do in iGantt. Using the view definition form, you can group your activities by multiple attributes already within the model. Click OK, and the activity chart automatically snaps into a new tree-type display according to the attributes you have chosen.
