A computer program product, comprising a non-transitory computer readable hardware storage device having computer readable program code stored therein, said program code executable by a processor of a computer system to implement a method, for reference model-based, requirement-based development of a technical system, wherein,
- in relation to a technical reference system containing a plurality of reference system components that each contribute to the functioning of the technical reference system and are represented in digital form by a stored digital twin as a complex reference model of the technical reference system, reference model requirements of reference model components for the development of the technical system are able to be forwarded by accessing the digital twin, the reference model requirements containing
- statements about required properties and capabilities of the reference system components that the reference system components have to meet in order to comply with text-based document specifications, standards and/or specifications and provide certain performances, or containing statements about required properties and capabilities of the technical reference system that the technical reference system has to meet in order to comply with text-based document specifications, standards and/or specifications and provide certain performances,
- wherein
- the program code is configured to
- a) orchestrate access to the digital twin in order to forward a suitable reference model requirement from the forwardable reference model requirements of the digital twin, in which
- access is orchestrated by way of user-based data and command input and logic-based data processing and command implementation in accordance with a stipulation based on a set of rules, and for a dedicated system component provided for the development of the technical system, which contributes to the functioning of the technical system, with a dedicated requirement, which is allocated to the dedicated system component, in relation to the technical reference system containing the reference system components, the suitable reference model requirement from the forwardable reference model requirements is ascertained,
- a1) in a first orchestration phase, a storage location in the digital twin is ascertained for the suitable reference model requirement suitable for the development of the technical system,
- a2) in a second orchestration phase, a relevance of the suitable reference model requirement belonging to the storage location and relevant to the forwarding is ascertained from different perspectives for the development of the technical system,
- a3) in a third orchestration phase, the suitable reference model requirement is extracted from the storage location in accordance with the ascertained relevance, and
- b) forward the extracted suitable reference model requirement.
