Dump Sequencing

To access this dialog use one of the following:

Activate the Schedule ribbon and select Model | Dumps | Sequence.

The Dump Sequencing dialog is used to select a set of dump evaluation data and generate a dump block sequence.

The Dump Evaluation dialog first needs to be used to generate the data required as input into the dump sequencing process.

Field Details:

Dump Data:

Definition: select a dump definition object from the dropdown.

Wireframe: select a dump wireframe object from the dropdown.

Outlines: select a dump block outlines (strings) object from the dropdown.

Filter by Lift: select this option to filter the data by lift number.

Lift Number: select a lift number from the dropdown.

Lift Entry Blocks:

Lift Block grid: lists the Lift and Block values.

Pick: select blocks interactively from the Design window.

Dependencies:

Dependency Table: optionally select a dependency table from the dropdown.

New: create a new dependency table.

Dump Dependency grid:

Leader: first block in a dependency.

Follower: second block in a dependency.

Add: add a new dependency to the grid and define Leader and Follower parameters.

Auto: optionally, automatically generate dependencies for the filtered blocks.

From String: define dependencies by selecting a sequence indicator string(s) in the Design window.

Remove: delete the selected dependency from the grid.

Remove All: delete all dependency entries from the grid.

Sequencer:

EFH Factor: enter a value for the effective flat haul factor.

Sequence: sequence the dump blocks using the parameters defined in this dialog.

Start Animation: animate the dump block sequence and display it in the VR window.

Dump Sequencing

The Dump Data files are generated by running the Dump Evaluation activity. The Dump Definition file initially just holds the BlockID and volume of each dump block. After sequencing the dump blocks, the dump block sequence number is added to this file.

A lift entry can be selected for each lift by picking a dump block. An icon of a truck is shown to signify that this is the lift entry. Only one lift entry is allowed per lift. A lift entry can be deleted by selecting the row in the grid and pressing delete.

Using the Sequencer

The EFH Factor (effective flat haul factor) is used to factor the distance between lift entry blocks on adjacent lifts. This compensates for the slower speed on a ramp and will mean that although a block on the lift above may be the next nearest block, the actual cycle time will be longer and dumping should in fact continue on the current lift.

The Sequence button is used to calculate the dump block sequence number for each block based on a dumping sequence that minimizes the haul distance. The dump block sequence number is then stored in the definition table.

Once the blocks have been successfully sequenced, the dump sequence can be viewed in the VR window by clicking Start Animation. The animation is launched automatically and the view is centred on the current dump wireframe.

Creating Dump Dependencies

The dependency between dump blocks can be created using the following procedure:

In the Dump Sequencing dialog, Dependencies group, click Add,
Pick the Leader and the Follower,
Click Auto ,
Check that all overlapping blocks are automatically linked.

Dependency links can be created from a simple string that passes through the required dump block outlines; the generated dependencies link the blocks in the same order as the strings points.
