HI. Network Analysis

You can change the location of these tabs by dragging them to any convenient place.

This section uses the default display order of these tabs in the current to-date version of Haul Infinity.

The Properties tab provides information about the selected network object(s).

A more detailed explanation on this tab can be found here.

Error List tab

When making changes to the network, you should always keep the Error List open.

Error List also now provides a warning on the tab to show users potential network issues without opening the tab.

• Double click to zoom to and select erroneous objects.

• Some errors can be reported twice - like isolated node and unsnapped point.

  • Note that all isolated blocks must be connected to the network, otherwise you won’t be able to proceed to the scheduling.

• Use automatic error correction feature (Autofix) with caution, so that you don't get unexpected outcomes.

• Similarly with the Hide feature - make sure that you do not hide critical errors.

• Some warnings won't show up in the Error panel: zero tons bucket, zero tons tray, no road connection between source and destination

See the section HI. Error List Resolution for examples of possible errors and ways to resolve them.

Error thresholds can be changed.

To do this, open the Project Settings window (via the dropdown of the Tools button) and flag the boxes for the types of errors that should be displayed in your project and the thresholds for the applicable parameters.

Segments tab

1. Select the haul route for which you wish to display the segments data from the network viewport or from the History panel on the left.

2. The data for each segment of this route will be shown for the Truck, Loader, Material and Operating Conditions selected in the Route Selections panel.

3. Double-click on a segment from the list to zoom to it in the viewport. A large green arrow will point to the selected segment.

   1. Alternatively, you can select a segment from the list and press the green arrow button to jump to it in the Viewport.

4. Segments data can be reviewed and exported form this tab, but not available for editing.

5. Segments data are split into Loaded and Unloaded.

6. You can review Spotting, Queuing, Loading and Dumping times for each state (loaded and unloaded).

7. Check the Subtotal to see the sum of each parameter.

Select the network segment(s) from the list or viewport and check the data, such as

• Distance of each segment, in meters,

• Gradient, in percent,

• Rolling Resistance, in percent (RR),

• Maximum Speed, in km/h,

• Final Speed, in km/h,

• Percentage of travelling with a load,

• Segment travel time, in minutes,

• Actual Max Speed, in km/h,

• Actual Final Speed, in km/h,

• Average Speed, in km/h,

• Elevation Change, in meters,

• Fuel Burned, in liters, if applicable,

• Battery Used, in kWh, if applicable,

• Battery Regenerated, in kWh, if applicable,

• Net Battery Usage (Used - Gen), in kWh, if applicable,

• Trolley to Motor efficiency, in kWh, if applicable,

• Trolley to Battery efficiency, in kWh, if applicable,

This tab also includes options for exporting segment data to Excel, DXF, and XML files.

Charts tab

1. Select the parameters upon which you wish to show the chart:

   1. it can be Distance or Time for the X Axis, and

   2. Elevation, Velocity, Fuel, Battery and Trolley data for the Y Axis.

      1. You can select one or multiple parameters for the Y Axis.

2. In the Trucks list flag trucks that charts you wish to display.

3. Specify Primary and Secondary Axis Scales (Auto by default, untick to modify).

4. Overlapping road signs on the chart can be dragged across the charts area or hidden (Show Signs checkbox).

5. Toggle Show Waypoints checkbox to show/hide network waypoints.

6. Hover the mouse cursor over the chart to see position of the truck on the road in the Viewport.

   1. You should see how the truck accelerates, slows down when passing the corners, stops for loading/unloading.

7. Press Export to Excel to export the chart and the its data breakdown to Excel.

Truck Times tab

1. Select the haul route for which you wish to display truck times from the network viewport or from the History panel on the left.

2. The data for each truck time will be shown for the Material, Loader and Operating Conditions selected in the Route Selections panel.

3. Unflag the Include Fixed Time checkbox if you don’t want to display non-productive truck times on the graph, ie:

   1. Queue time, Load Time, Spot at Loader Time, Spot at Dump Time, Dump Time, TKPH Delay Time, Recharge Time, and Recharge Travel Time.

4. Flag the Show Chart Waypoint Breakdown checkbox to breakdown the graphs by waypoints (if any).

   1. each truck’s graph will be split into part To and From the WayPoint, where numbers on the Legend represent Source and Destination blocks numbers.

5. Hover the mouse cursor over the required truck graph to display the applicable cycle time values.

Cycle Time Analysis tab

In the Cycle Time Analysis panel on the left see a detailed analysis of time cycles, applicable to the Loader, Truck, Material and Operation Conditions, selected in the Route Selection panel.

The Cycle Time Breakdown panel on the right displays the ring chart of cycle time breakdown into the intervals listed in the legend. Toggle the percent icon in the top left corner to switch units from minutes to percent.

Schedule Auditor tab

Haul Infinity will then generate the full cycle time breakdown and 3D haul strings for each schedule record. This can be used to estimate truck fleet mobilisation and utilisation over time.

1. Import Schedule from the Scheduler or CSV file, following the instructions below or in the section HI. Process a Schedule.

2. Double click any line in the list to animate the selected haul in the viewport.

3. Use the arrow keys to move forward and backward through the imported schedule; this lets us inspect the haulage solutions provided by Haul Infinity and make any functional changes to the network as required.

4. Flag Zoom on Select to zoom to the selected haul in the Viewport.

Importing Schedule from Scheduler

If you are using Haul Infinity within the Scheduler (ATS or APS), you can import a schedule directly.

1. In Alastri Tactical/Production Scheduler:

   1. Run all the Setup Tasks.

   2. In the Schedule tab, run Scenario or Full Schedule.

2. In Haul Infinity:

   1. In the top tab bar locate the Scheduler tab.

   2. Select “Import from Scheduler”.

      1. Imported strings will be displayed as a list in the Scheduler Auditor tab.

   3. Double click any line in the list to animate the haul in the viewport.

Importing Schedule from CSV

To import scheduling transactions from CSV file:

1. In the Schedule Auditor tab click the Import Schedule button.

2. Select a CSV file which contains the schedule to be imported.

3. Click the blue plus icon to create a new CSV mapping template.

4. Drag and drop the CSV column headers to the corresponding schedule field. The ID and Flag fields can be left blank.

More detailed description of the importing functionality, as well as examples of its use, see here.

Exporting Schedule

Once you have audited the schedule to your satisfaction, the calculated results can be exported for use in cost modelling and fleet selection.

For a detailed description of this tab, as well as examples of its use, see here.
