Requirements, stakeholders' visions, drive any systems engineering (SE) process. But in design process practices, there is a gap often present between stakeholders' visions and requirements representation. This limits the impact that the stakeholders can provide input to the SE process. Then, the process may end up with errors or provide a product which is unwanted. We proposed a design methodology...
Modeling and Simulation methods, tools and techniques aim at supporting the different phases of the lifecycle of modern systems, going from requirements analysis to system design and operation. However, their effective application requires investigating several aspects such as the formal modeling of system requirements and the binding and automated composition between heterogeneous models (e.g. requirements...
The development of context-aware applications is a complex process that involves context management. A context life cycle implies 4 essential steps: context acquisition, context modeling, context reasoning and context dissemination [1]. In [2], we tackled the issue of context modeling and reasoning by proposing an approach based on Relational Concept Analysis (RCA) and Descriptive Logic (DL), respectively...
The objective of Model-Based System Engineering (MBSE) is to provide the right tools to create and manage all life-cycle information in a pragmatic, concise, consistent and traceable way across the numerous perspectives and architectural levels. Its practical use, however, is currently impeded by a universal lack of experience and integration with development processes. Interested engineers therefore...
