Research

Design of mechatronic systems is a complex process. The systems themselves are becoming complex due to an increase in functionality and behavior intelligence. On the other hand, the development process naturally involves multiple stakeholders which have different viewpoints, supported by multiple views to address their concerns. Modeling is performed at various levels of abstraction and detail to represent the system based on the concerns of the stakeholder. As a result, multiple formalisms, modeling languages and tools are utilized. Such multi-view development processes presents a number of challenges:
  • Overlapping concerns: Results in views that are not entirely independent, but have relations between them.  
  • Dependencies: Due to the nature of design process and overlapping concerns, product properties captured in models influence each other - called as dependencies. The dependency management in general is implicit and ad-hoc.
  • Information exchange:  Exchanging and understanding information between a diverse set of stakeholders is a challenge due to the existence of different terminologies and backgrounds.
  • Tool interoperability and tool integration is a major hurdle.
  • Consistency management and model management is challenging and difficult to enforce.

Our aim is to study methods and approaches and develop the supporting tools that address the above mentioned challenges and support the designers in their work.
