Combining System Models and CAD for Change Scenario Management

Abstract

In the development of complex mechatronic systems, interdisciplinary cooperation requires an exchange between stakeholders in order to ensure fulfillment of requirements and related functions. The cooperation of the stakeholders from different disciplines must be well coordinated to address systems changes. The system model as an essential aspect of model‐based systems engineering, has to be linked to specific models of involved disciplines (mechanical, electrical/electronical and software) to enable a basis for automatic identification e.g., of affected subsystems and functions. This contribution discusses the potential of model linking from the perspective of change scenarios by considering published approaches to link system models and computer‐aided design (CAD). A methodical approach on how descriptive system models can be used as base for computer‐aided design is presented. This approach is analyzed by reviewing a use case for a design change scenario of an automotive eAxle.

Utilization of system models in model-based systems engineering: definition, classes and research directions based on a systematic literature review

“…Shown by the class of semantic integration and model transformation, the information stored in the system model can be used to compensate development efforts in other stages of the product creation or along the value chain. However, change scenarios and their handling require switching between the layers in the V-Model (Hick et al 2023). For example, a change of a requirement will lead to an impact propagation analysis, often conducted on the physical layer to analyse the effect on specific subsystems and components.…”

“…The different classes distinguish fundamentally different approaches for the further reuse of SysML models with different aims and necessary efforts. While model transformations might aim to transfer individual diagrams into domain-specific models, such as shown in the transfer of electrical system designs between the Siemens tools Capital Systems Capture and System Modelling Workbench (Hick et al 2023), others will require the collection of information from the whole model. Especially the transfer of the visual layout of a diagram into domain-specific tools will cause tremendous effort to develop certain modelling guidelines to ensure a transfer without information loss and, most importantly, a benefit with the domain or discipline-specific model.…”
