System modeling demonstrates the route toward making dynamic models of a system, with each model showing a substitute view or perspective of that system. We use different UML diagrams, which show the pictorial view of our system, such as: ER diagram, activity, and component diagram.

component diagram a diagram describing the relationships among the components of a systems. In object-oriented programming it is frequently called object diagram and includes relationships of is-part-of and those by means of method calls.
Requirements and architecture definition subprocess

Depict all elements of the system, and interactions among them and the customer environment in component diagram form. Include existing logistics support equipment. A typical format used here is the Schematic Block Diagram (SBD).

Other process modeling techniques and tools were also preferred. For example, BPMN workflow diagrams are used to illustrate the business procedures and setup activities in a cloud-based platform (Alreshidi et al., 2016) or represent the process model in a cloud-based business environment (Shamsuzzoha et al., 2017). BPMN is also employed to exemplify the collaborative business processes in collaborative industrial ecosystems (Kannisto et al., 2018). J. Wang et al. (2019), however, developed a flowchart for modeling business processes of a mining technology collaboration platform. IDEF0 diagrams were developed for the main node decomposition of multi-agent virtual enterprise systems (Sadigh et al., 2017) and the decomposition of a collaboration platform’s business process model (J. Wang et al., 2019). Vatankhah Barenji (2022) make use of Petri-nets process diagrams to demonstrate the interactions among the units and block trust in peer-to-peer network prototyping. The authors also described the architecture from other viewpoints like development and deployment. However, a few of them were modeled using formal notations. A UML component diagram, for example, was developed to show the components of a smart city innovation ecosystem by Javed et al. (2020), and a UML deployment diagram catered for the design of a testbed architecture from a deployment viewpoint by Demichev et al. (2021). Aulkemeier et al. (2019) described the architecture of platform-based collaborative ecosystems using ArchiMate notations, by illustrating the components, actors, and interaction mechanisms in the platform.
Introducing a system theoretic framework for safety in the rail sector: supplementing CSM-RA with STPA
Published in Safety and Reliability, 2020
Ross Dunsford, Mikela Chatzimichailidou
In the CSM-RA stage of System Definition (Section 4.1), it was mentioned that safety engineers develop the system definition based on engineering design and specification material, and the system definition will often include diagrams illustrating a physical model of the system. Undoubtedly, those diagrams can be useful in understanding the system boundaries (e.g., context diagram) and how each subsystem works, however they are often unconnected representations that provide scattered information and thus do not always shape a unified and holistic picture of the system under assessment. To remedy this, the STPA control structure can be used in addition to those diagrams. In STPA, a systems-theoretic causality model is used rather than the chain-of-events causality model used in other techniques; this means that it depends on a functional control diagram rather than a physical component diagram (Leveson, 2011). As the main difference between STPA and other traditional hazard analysis techniques is the model employed, context diagrams can be replaced with control structures which illustrate the hierarchy of control and authority within the system. The control structures use abstraction so can be applied to manage complexity but are also useful when the design is not developed and therefore can be used at the early stages of the lifecycle when design information is not available10, allowing hazard identification to begin earlier.
A design method for edge–cloud collaborative product service system: a dynamic event-state knowledge graph-based approach with real case study

Unified modelling language was originally developed based on object-oriented analysis and design methods, and its key idea is to provide standard language for system design and visualisation (Liang and Jin 2020). Generally, UML can be separated into Structural UML diagrams (e.g. Class diagram and Component diagram) and Behavioural UML diagrams (e.g. Activity diagram and State diagram). Many researches have reported the application of Behavioural UML diagrams in activity flow modelling. For example, Zhang, Jiao, and Helo (2007) developed an UML-based process platform to model the standard configuration and representation of similar production processes within product families.
