The Decision module

The Decision module allows for decision-making processes in the system.

This module allows for decision-making processes in the system.

It includes options to make decisions based on one or more conditions (eg at a quality inspection point, if the entity type is pass or fail) or based on one or more probabilities (eg 75%, true; 25%, false).

Typical uses include dispatching a faulty part for rework, branching accepted vs. rejected checks, or sending priority customers to a dedicated process.

Conditions can be based on:

  • Attribute values (eg change the status of a product after inspection to either pass or fail)
  • Variable values (eg counting up to 10 boxes to fit on a pallet with a capacity for 10 boxes only)
  • The entity type (eg differentiating between economy class or business class booking types)

There are two exit points out of the Decide module when its specified type is either 2-way by chance or 2-way by condition. There is one exit point for ‘true’ entities and one for ‘false’ entities.

When the N-way by chance or by condition type is specified, multiple exit points are shown for each condition or probability and a single ‘else’ exit. The number of entities that exit from each type (true/false) is displayed for 2-way by chance or by condition modules only.
