N2 - This research note presents a data model that defines the
key artefacts of the systems engineering and safety
processes of machine control systems. Existing data
models, like the ISO 10303-233 and the German automotive
specifications, especially MSRYS, are exploited when
defining the model.
The model presented in this research note defines
artefacts related to the overall system and its context,
requirements and their validation, risk assessment,
behaviour (system use cases and functional
specifications), system structure and documentation. The
emphasis is on defining the linkage between these
artefacts also across process boundaries. These links
form the traceability chains from risk assessments to
safety requirements, functional specifications, designs,
implementation, verification and validation. Besides
providing traceability of artefacts, such a model allows
centralized, single source, data repository
implementations that ensure a consistent view of
artefacts in different design disciplines, such as
software development and electrical CAD.
Two implementations of the designed model are presented:
Polarion ALM and MySQL with an MS Access front-end.
Examples of tool integrations using the model are also
demonstrated.
The benefits are also emphasized from the perspective of
documentation. A centralized artefact repository can
support the automated creation of documents based on
demand. For example, the system requirements
specification and the relevant parts of the technical
file, which is required by the Machinery Directive, can
be generated from the database.
