Using RELAX, SysML and KAOS for Ambient Systems Requirements Modeling

Using RELAX, SysML and KAOS for Ambient Systems Requirements Modeling

Ambient Systems are highly adaptive. They modify their behavior at run-time in response to changing environmental conditions. For these systems, Non Functional Requirements (NFR’s) play an important role, and one has to identify as early as possible the requirements that are adaptable. Because of the inherent uncertainty in these systems, goal based approaches can help in the development of the...

bCMS requirements modelling using SysML/KAOS

In this paper we have modelled an illustrative subset of the requirements of the bCMS case study using a combined approach called SysML/KAOS ̇. This submission is part of a broader effort that aims at the comparison of those three specific requirements modelling techniques (see [1], [2], [3], [4]). Keywords—goal-oriented requirements; SysML; functional requirement; non-functional requirements

A Comparative Study of RELAX and SysML / KAOS

This report explains two methods used for defining Non Functional Requirements (NFRs). Of the two methods one is RELAX which is a requirements engineering language; used to divide requirements into invariant and RELAX-ed. RELAX-ed requirements can be functional or non functional and is an enhanced form of the original requirement. SysML/KAOS has introduced the concept of goals in SysML; infect ...

The SysML/KAOS Domain Modeling Approach

A means of building safe critical systems consists of formally modeling the requirements formulated by stakeholders and ensuring their consistency with respect to application domain properties. This paper proposes a metamodel for an ontology modeling formalism based on OWL and PLIB. This modeling formalism is part of a method for modeling the domain of systems whose requirements are captured th...
