Cyclic modeling

You can model for the same stage, the same product group as the main product group and the inflow product group using the cyclic modeling.

For example, for a filtering stage, you can schedule the filtering of smooth pulp again with this product group configuration:

• Two inflow product groups for coarse pulp and smooth pulp
• One main product group for smooth pulp

This configuration translates into these process steps:

1. The initial filtering process step is defined as version one. In this step, coarse pulp is defined as the inflow product and smooth pulp as the main product.
2. The second filtering process step is defined as version two. In this step, smooth pulp is defined as the inflow product and the main product.

For the same stage, you can use cyclic modeling for recurring production operations, for example, pumping and mixing.

• Pumping use case

  In the crushing stage, you specify a process step as version one with these operations:

  1. Crushed material is produced using a crusher.
  2. The crushed material is stored in the appropriate tank after the operation mentioned in the above step.

  The stored crushed material is subject to a second process operation, for example, cooling, solidifying, or pumping. A dedicated resource, for example, a cooler or a pump, is used. After this operation and in the same stage, the material is stored in another tank.

  In the same crushing stage, you can model the second process operation and the subsequent storage into a process step as version two. The outflow of the version-one process step is the inflow of the version-two process step.

  The second process operation is considered as an integral part of the crushing stage. The intermediate material does not require a separate material code between the first and the second process of the crushing stage.

• Mixing use case

  In the mixing stage, you specify a process step as version one with these operations:

  1. Mixed material, for example, strawberry syrup, is produced using a mixer.
  2. The mixed material is stored in the appropriate tank after the operation mentioned in the above step.

  In case of excess strawberry syrup, the material can be combined with another inflow product. For example, raspberries can be added on the mixer to produce strawberry and raspberry syrup.

  In this case, the main product of the mixing stage, that is, strawberry syrup, is also the stage inflow product.
