Worker Models

This section contains classes that are relevant for defining worker instances.

Worker

The class Worker allows the definition of worker instances. This class is used to represent a specific worker in the production system.

As of today, the class just inherits its parent’s properties and relationships, but it’s worth be noted that having a dedicated class enables a fine-grained management of the HDT entities by the HDT user. For example, measurements related to workers may require additional data preserving rules (e.g., when collecting biometrics data); moreover, workers can be “anonymized” within the HDT (e.g., the referenceCode may be missing or an anonymous code), while this operation is meaningless for other factory entities in almost all the cases. Moreover, the behaviour of factory entities is in general predictable with well-established models, while the behaviour of workers may be unpredictable (due to non-measurable features, like emotions), and this point plays a crucial role in an HDT. For this reason, it is important to distinguish workers from other nonhuman factory entities.
