Ranges

Each demand element, should have a list of ranges.

If there are no items sorted in the source material or demand, it can not be used in the distribution calculation. So much in the calculation of DMT.

Each Range item will have the following properties:

1. Name - Item name. For items of type Arbitrated, you can specify any name. For items of type Calculated, it is the DDM program that chooses the name, based on the Code of the source or demand and an incremental counter
2. Group - Item group. When the >Group sources and demands option is selected, when you sort areas and volumes, each ranked item will have a group. Note, demand items can have the same group, for example the landfill bodies can be all grouped as Landfill-XXX, where XXX is a numeric index and would encompass the landfill and landfill with selected material (final layer). The same can be considered for backfills.
3. Type Type of item, can be:
   • Calculated - Are calculated by the program by clicking the sort
   • Arbitrated - When determined by the user. In the case of soft spot soils, sections are not evaluated to determine the volume, but rather evaluated by the area and depth of occurrence.
   The Classify has no effect on items Arbitrated
4. Start Raw Station - linear distance from the start of the alignment to the starting point of the item
5. End Raw Station - linear distance from the beginning of the alignment to the end point of the item
6. Average Raw Station - Average center or mass station of the item. The DDM program uses the arithmetic mean weighted by the cross-sectional areas to get this value
7. Geometric Volume - Accumulated geometric volume of the item. The items of type calculated use the cumulative values ??in the Volume column of the Areas and Volumes tab between the start and end steps
8. Distributed Volume - Volume that was actually distributed in the distribution tab. In the case of know dump site or unknown dump site that should have type defined for variable. This value must be less than or equal to the geometric volume. For those defined for fixed type, they should be the same, or the distribution will not be correct
9. Dead Distance - In the case of Borrow Pit or Dump Site, these may be outside of the domain strip from the project. Thus, it is mandatory to walk a distance to this item. Note: for the DMT calculation, you must be informed in which station will be the access point of the item, so the DMT between two items will be:
   
   DMT = ABS ([Average Raw Station of Source] - [Average Raw Station of Demand]) +
   [Dead Distance of Source] + [Dead Distance of Demand]
10. Start Station - Converted value of the initial raw station as a function of the parameters of station equations
11. End Station - Converted value of the final raw station as a function of the parameters of station equations
12. Average Station - Converted value of the average raw station as a function of the parameters of station equations

The Classify button can have one of the following states:

• Classified - When the button is pressed and the ranges are recalculated, the button looks like this, indicating that the items are updated
• Outdated - area or volume or even source and demand is changed, the button changes to this state indicating that the ranges are outdated

Caution!
When classifying items, or modifying any item in the ranges tab, the DMTs are automatically recalculated. Any edits to the DMT tab will be lost.

If any value is invalid, the text will be in red, indicating the error.

Cells with yellow background, are editable. Cells with white background, are read-only.
