Variable Definitions, Ranges and Default Values

The following table shows a brief description of the variables appearing in this tab. The table also displays their default values and their generally acceptable range:

Variable

Default Value

Range

 

● Entering Entity Description
The description of the discrete entities that are fed into the equipment unit.

<Entity Name Unknown>

Any Text

○ Exiting Entity Description
The description of the discrete entities that are transferred out of the equipment unit.

<Discrete Entity>

Any Text

● Operating Throughput per Unit (entities/h)
The feed rate of discrete entities per equipment unit.

0.0

Positive

○ Power Type
Indicates the power type that is used by the operation. Click on the list box to bring up a list of available power types in order to select one.

<Std Power>

Any Power Type

◙ Specific Power (kW/(Entity/h))
The power consumed for the operation per feed rate of discrete entities.

0.0

Positive

◙ Total Power (kW)
The total power consumed for the operation (per cycle).

0.0

Positive

◙ Power Per Unit (kW)
The power consumed for the operation per equipment unit.

0.0

Positive

○ Setup Time
The amount of time (per cycle) spent before each operation is carried in preparation for the actual execution of the operation. It may involve actions like cleaning, vacuuming, setting up of equipment, etc. which the user opted not to model explicitly.

0.0

Positive

◙ Process Time
The actual duration of the operation (per cycle).

60.0

Positive

○ Ignore Labor?
Check this box to ignore labor for this operation. This option is used only if the process time is set by a master-slave relationship.

Yes

Yes/No

Symbol Key: ○ User-specified value (always input); ● Calculated value (always output); ◙ Sometimes input, sometimes output

Specification Choices / Comments

The following list describes the available specification choices in this tab; for more details on how these are implemented, see Discrete Pass-Through (in a GBX): Modeling Calculations.

This operation can be useful in simulating processing steps that involve no physico-chemical transformation, yet they incur some cost (e.g. inspection, weighing, etc.).

The operating Throughput variable is calculated by the program. The user specifies the name of the Exiting Entity.
