Model Based Systems Engineering

Development of mechatronical products demands special multidisciplinary requirements related to the product development process. In the research field of 'Model Based Systems Engineering' approaches for interdisciplinary model based product specification in the early development phase and subsequent multi-physical simulations are developed. Investigations are done within the publicly funded research project 'mecPro2' and in close collaboration with the industry. Additionally, the research project 'InnoServPro' of the Federal Ministry of Education and Research (BMBF) addresses later lifecycle phases by an integrated model based description systematics for service products by usage of real-time data acquisition. To support the practical applicability of the approaches, concepts for administration of the resulting system models within PLM-solutions are developed in both research projects.
 

Motivation

Innovative, interdisciplinary product development requires rethinking today’s methods, processes, IT solutions and forms of organization. Especially, appropriate IT solutions for functional description and layout of system architectures are missing. Eventually, Model Based Systems Engineering (MBSE) could be established as integrative method to connect different classical engineering disciplines with each other. In future PLM solutions should support the product development process more consequently. After the definition of requirements also development results from the concept phase should be administrated on the SysLM backbone. The system model should support discipline-overlapping simulations and clear allocation of tasks to the respective engineering discipline according to a given partitioning. Moreover, the functional product description should connect the requirements and the product structure during a change tracking within the PLM solution.

Research

The central data objects of a SysML system model, which includes development requirements, functional structures and logical product structures, are transformed into a data model for integration in the PLM solution. The defined system model should be editable by existing SysML editors and the generation of the model should be carried out iterative. Furthermore, the conversion in the PLM solution takes place by applying the SE VPE data schema which defines all object and relation types within the system model. The SysLM backbone provides functionalities for administration so that members of all classical engineering disciplines can be easily involved in the development. Additionally, the integration in the PLM solution allows traceability at the element and property level.

Therefore, following problems regarding research can be expressed:

  • How can the interdisciplinary character of a system model contribute to a better traceability of dependencies between product requirements and development results within a PLM solution?
  • On which level of detail are relations between elements of the product description necessary for the traceability of their dependencies (element/property level)?
  • How is it possible to also administrate the internally connected structures of the system model of the PLM solution (e.g. material and signal flow in functional models or various relations within elements in the system architecture)?
  • Which further aspects of the system model (e.g. system behaviour, use cases, analysis views) are in need of centralized administration (variant and change management or versioning) within a PLM solution?

Results

  • Integration of SE in the development process which is controlled by the SysLM backbone
  • Traceability of eventual effects on the requirements by changes
  • Early requirement-orientated and functional-orientated system specification
  • Reference model for discipline-specific tasks in the detailed development
