Process nodes are used to model transformations of material state or grade and are optional.
Process nodes have the following properties:
Name - the name of the process node as it appears in XECUTE reports, Data Feed Out and configuration tables.
Rate - the production rate of the process node.
Override per period - the process production rate can be overridden per period. Configure the overrides by clicking the dial icon and enable the overrides by selecting the Yes option for the field.
Use Sub-Process nodes to apply different allocations or splitting behaviour on the incoming material. You can define the allocation of material from Process node to Sub-Process node, (Predefined option), or it can be managed by PO (Optimised option).
If a Process node has Sub-Process nodes, Transformations can only be applied at the Sub-Process level.
A Process node can have two or more Sub-Process nodes. Deleting a Sub-Process node will remove the node and the material flow links to and from it.
This control is enabled if Transformations are NOT configured.
Sub-Process nodes are added to a Process node by:
If the splitting option is set to Predefined, the material (Mass) is split between the Sub-Process nodes based on Transformation expressions (see below). Each Sub-Process node may transform 0-100% of the parent Process node mass.
If no Transformations are applied, 100% of material will pass through each of the Sub-Process nodes.
If the splitting option is set to Optimised, PO will manage the material flow and apply any Transformations (if present).
This option is enabled if Sub-Process nodes are NOT used.
When material enters a Process or Sub-Process node it is possible to apply an expression-based processing transformation to any of the principal fields of the inbound material. Transformations on Process or Sub-Process nodes are optional. If Transformations are not applied to Process or Sub-Process nodes, 100% of the material will move through each node.
Dump Time Penalty - if a haulage model is imported into the site this field is enabled. This field allows custom dump times to be applied for the process rehandle operations. The penalty is in addition to the Dump time configured in Site Management.
Add Named Location For Spatial Domain - for this field to appear the site must have more than one spatial domain and each domain must have a haulage model imported.
For the field to be enabled, at least one inbound movement arrow for the stockpile must be set to use the Modelled haulage calculation method.
In the field dropdown, select the spatial domain that has the haulage model with the named location to be mapped at the Named Location field.
Click the Green + to add the named location mapping field (see below).
Multiple mapping fields can be added and in fact are required when a named location is used to join haulage models.
Domain Name (Named Location) - the named location in the haulage model associated with the specified spatial domain that corresponds to the process node. For single spatial domains the Default Domain is used. If more than one domain is configured for a site the Domain Name is named after the spatial domain selected in the Add Named Location For Spatial Domain field.
