Characteristic Models

Tue, 01 Oct 2024 00:00:00 +0000

This set of classes allows to define quasi-static and static data describing workers and factory things.

Note that the required model attributes are indicated with a red asterisk ("*"). For mandatory relations, refer to the multiplicity instead, as relationships are defined on one side only (i.e., a specific relationship might be described within the other related entity).

Common Descriptors

Tue, 01 Oct 2024 00:00:00 +0000

The classes belonging to the Common Descriptors allow the description of properties, characteristics, measurements, dimensions and states of the many entities operating in a factory, including workers, machines, robots and devices.

State Models

Tue, 01 Oct 2024 00:00:00 +0000

This set of classes aims at describing states characterizing factory entities. States are computed by functional modules, which describe all those computational processes that can elaborate entities and attributes, making the HDT capable of simulating, predicting, reasoning, and deciding. The class FunctionalModule aggregates one or more events that can be used to update the state of the HDT depending on the result of the computation performed. Inputs are defined and mapped through the class FunctionalModuleInput to the entities needed by the model (e.g., physiological parameters and worker conditions for detecting fatigue level). Internally, functional models can employ any mean of data processing and calculation such as mathematical functions, machine learning, or empirical models. These, if necessary, can be stored as binary blobs and annotated to be managed correctly.

Worker Models

Tue, 01 Oct 2024 00:00:00 +0000

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.
