Transportation Process Assignments

Internal Table Name: TransportationProcessAssignments

Use the Transportation Process Assignments table to create rules for selecting which Transportation Process to use when multiple processes are available. You can also link a process to another process. In addition, this table enables you to determine which processes can be used in which periods.

Simulation: Available only in Classic Simulation.

Period

Technology: NO S

Table: TransportationProcessAssignments

Internal Name: PeriodName

Type: Short Text (50)

Select one of:

• the specific Period to which the Transportation Process Assignment applies,
• (ALL_Periods) to apply the assignment to the complete model horizon,
• the Period group to which the Transportation Process Assignment applies in a multi-period model.

Period assignments work as follows:

• (ALL_Periods) only assignment – The process is assigned to the entire horizon of the model. In a multi-period model, the assignment is for all periods.
• (ALL_Periods) with additional period assignments – The horizon-level record (ALL_Periods) sets the basis for the assignment policy and costs. Period-specific assignments override the horizon assignment for the period specified.
• Period-Specific Assignments Only – The process is assigned to the periods specified and unavailable in other periods. If there is no process assignment defined in a period, the model can still produce and transport the product; it does so without using a process. For example, if you define an Transportation Process Assignment for Period 1 only, the product will still be produced and transported in the other periods, but without the specific Transportation Process.

Assignment Policy

Technology: NO S

Table: TransportationProcessAssignments

Internal Name: SelectionRule

Type: Short Text (255)

Select the Assignment Policy that determines how the Transportation Process Assignments will be used. Each site-product pair must have the same Assignment Policy for all process options. Some Assignment Policies are affected by the value of Policy Parameter:

Default: None

This field is used in conjunction with the "Split by Ratio", “Split by Probability”, and “Link to Process” Assignment Policies.

• Split by Ratio – Define the ratio between multiple processes on the same Site-Product combination. These are then used to generate the proportional split. For example, if you have two processes that can be used with a “Split by Ratio”, you could define the Policy Parameters as 6 for one record and 2 for the other. Based on the ratio between these two values, the Transportation Process Assignment would be 75% for the first record and 25% for the second.
  You can express the Policy Parameter as 0 to 100, or 0 to 1. For example, values of 25 and 75 are evaluated the same as values of .25 and .75.
• Split by Probability – the assignment is chosen based on the percentages set in the Policy Parameter field:
  • If the value is non-zero, use the exact value. For example, if you enter 50, then 50% uses this record. The Policy Parameter values should add up to 100, which represents 100%, however if the inputs do not add up to 100, the values will be scaled to 100 automatically.
  • If the value is 0, this is treated as 0% and this record is not considered (similar to setting Status = “Exclude”).
  • If the value is null, this record is considered “free”. In the case that all records with non-zero parameter values add up to less than 100%, the solver can determine the percentage for any free records. In the case that the non-zero parameter records add up to 100%, the free records are not considered (similar to Status = “Exclude”).
  You can express the Policy Parameter as 0 to 100, or 0 to 1. For example, values of 25 and 75 are evaluated the same as values of .25 and .75.
• Link to Process – Enter the name of the process to which the current process is linked. Only Transportation Processes are available when linking from a Transportation Process Assignment.
