When Softree Optimal calculates the cost of an alignment, it determines the lowest cost prescription (or recipe) for moving material. We call this the Optimal Haul. The Optimal Haul is a detailed description of how material is moved along the alignment, and from/to borrow/waste pits.

Traditionally the mass haul diagram has been used to represent material movements, however it has some drawbacks. The mass haul diagram does not fully expose the Optimal Movement Prescription. It does not provide a detailed schedule of earth movement between stations and it does not handle the concept of material quality introduced in the case of multiple materials.

The Optimal Haul Diagram addresses these two deficiencies.

The Optimal Haul diagram illustrates the Optimal Movement Prescription (as determined by Softree Optimal).
