Specification Choices / Comments

The following list describes the available specification choices in this tab; for more details on how these are implemented, see Transport Operations: Modeling Calculations.

Cost / Quantity Basis options...

The quantity per shipment and the various unit costs can be based on mass (metric tons), discrete entity, or volume (m3) of transported material. When volume is used as basis, the bulk density of the material is also required and it is either specified by the user or set equal to the feed stream’s density.

Default Values...

The default values for quantity per shipment and the various unit costs correspond to transportation by truck. The default values of the same variables for other modes of transportation (e.g., train, sea, and air) are different.
