The development of mechatronic products involves multiple stakeholders which have different viewpoints and therefore use different concepts, models and tools to deal with their concerns of interest. This paper argues that an increased emphasis needs to be placed on the relations between viewpoints to be able to deal with the evolving scope and requirements(More)
Embedded systems, with their tight technology integration, and multiple requirements and stakeholders, are characterized by tightly interrelated processes, information and tools. Embedded systems will as a consequence be described by multiple, heterogeneous and interrelated descriptions such as for example requirements documents, design and analysis models,(More)
Managing consistency is a major concern in the design of complex engineering systems. At times, inconsistencies may lead to wrong decisions, resulting in design flaws which can compromise safety and cause failures. One cannot forget the 1999 NASA unmanned MARS Climate Orbiter, which was destroyed due to use of inconsistent units by design teams. Sadly, the(More)
In this paper, we have investigated the role of dependencies in the design process of mechatronic products. Since explicit modeling of dependencies is largely considered unnecessary today, current languages do not support dependency modeling due to lack of sufficiently expressive language constructs. However, this paper argues that modeling dependencies is(More)
Higher demands on efficiency, cost and functionality have contributed a great deal towards the advent of Mechatronic systems where mechanics, electronics and computer software integrate together to provide the required functionality. This integration has its effects in the design process as well, and a good design requires careful integration of methods and(More)
This article reports on our ongoing experiences in developing visual analytics tools for real-world CESs. Our work focuses on the early design phase during which a large design space is explored, poor alternatives are pruned, and valuable alternatives are considered further. Visual analytics tools can provide interactive discovery, exploration, and(More)
The varying stakeholder concerns in product development today introduces a number of design challenges. From the perspective of Model-Based Systems Engineering (MBSE), a particular challenge is that multiple views established to address the stakeholder concerns are overlapping with many dependencies in between. The important question is how to adequately(More)
Designing and developing complex mechatronic systems requires the consolidation of models from a variety of domains. These models are created by different stakeholders using a variety of formalisms for the purpose of addressing specific concerns, and are used for representing different views on the same system. While it is considered good practice to(More)
