Model-based systems engineering (MBSE) is a methodology that supports the use ofmodels to better analyze and understand complex systems and create quality and cost-efficient products. The analysis is facilitated by platforms that support formal graphicalmodeling and provide complementary modules for testing, validation, code or documen-tation generation. Thus in specialized fields, researchers create...
It is important to manage traceability between requirements and other artifacts, including stakeholders, sources, and system development elements. Requirements are often expressed independently from those artifacts using textual and model approaches. This fact makes hard and tedious the inference of trace links between them. This paper proposes a new Domain Specific Language (DSL), called REQDL, for...
Mobile Devices offer enriched services and information for the end users. Achieving security in such a dynamic and heterogeneous environment is a challenging task. Hence, adaptive security is an applicable solution for this challenge. It is able to automatically select security mechanisms and their parameters at runtime in order to preserve the required security level in a changing environment. In...
Requirements traceability is handled in order to help stakeholders understanding existing dependencies between requirements and development artifacts. In this paper, we aim at taking advantage from system engineering and model-driven engineering field in order to automatically generate trace links from SYSML models. Our approach establishes a transformation of requirement diagrams and design diagrams...
Requirements traceability provides support to check that the final system meets stakeholders' requirements. Although the important role of requirements traceability is widely recognized, the application of traceability methods remains limited and varies from one development team to another. In this work, we aim at providing a common approach for requirements traceability in case of complex system...
Hospital Information Systems (HIS) have become the one way to improve the quality of healthcare and the working conditions of health professionals while simultaneously searching an economic efficiency. However, the HIS implementation is a difficult and complex operation due to the wide variety of end users and professional disciplines involved in the healthcare production process. This paper proposes...
Dynamic systems cause challenges for security because it is impossible to anticipate all the possible changes at design-time. Adaptive security is an applicable solution for this challenge. It is able to automatically select security mechanisms and their parameters at runtime in order to preserve the required security level in a changing environment. In this paper we describe an approach detailing...
For any organization, improving the business performance means perfecting their software development. Systematic reuse offers great potential of significant gains for an organization, by reducing costs and efforts, and accelerating the Time to Market of software products [1]. Cloud based development is a challenging task for several software organizations, especially for organizations that are in...
Process modeling is of paramount importance in organization. It is a powerful tool to manage and control all its activities. However, the diversity of approaches and standards proposing process modeling makes choosing a methodology for modeling processes a delicate work. This choice has become more difficult, given the increasing complexity of current information systems and requires the consideration...
Complex systems deployment projects usually face some major difficulties leading sometimes to spectacular failures. Efforts to overcome this complexity are focused mostly in adapting the concepts of project management engineering in order to be adapted as much as possible to the constraints imposed by those systems. This paper proposes a new approach to the problematic of a complex system deployment...
Processes for secure software development play a crucial role in the software lifecycle. They help organizations to meet security requirements throughout the development lifecycle. Among these processes, OWASP's CLASP and Microsoft's SDL are leaders for security support in the software life cycle. This has prompted researchers to compare and evaluate these two approaches in order to use them in an...
This paper aims to benefit from the advantages of the Web services on behalf of business process management. It proposes a Web service approach to manufacture agile processes in two main phases: design and discovery. On the one hand, it tries to answer the question: how to model business processes that are able to be performed by Web services? On the other hand, it describes a semantic matching algorithm...
The Web offers a variety of Web services on the Internet that can provide similar functionality. Thus, to ensure an automatic discovery including the selection of the appropriate service among other similar ones, the Web Service (WS) description must unfold outside its functional aspect through additional information describing its non-functional aspects. Many approaches have been proposed to enrich...
The WS (Web services) description is an important step in the services consumption's cycle. Semantic WS extends the capabilities of a WS by associating semantic concepts in order to enable better search, discovery, selection, composition and integration. Several WS description approaches have been proposed to present a detailed description exceeding the limitations of the syntactic standard WSDL....
Web services Description has been recognized as an interesting paradigm that attracted significant attention from the research community. Currently, several WS description approaches have been presented to complete a detailed description with all the required aspects. The WSDL standard remains incomplete to provide a sufficiently rich description to service consumers. Thus, WSDL extensions as SAWSDL...
The information security aspect has become a major concern for software project leaders. The problem is that software engineers still consider security issues as add-on requirements expressed and verified by “external” actors like auditors or security managers. We aim to help software engineers by identifying precisely what they are expected to do and to deliver at each step, in order to enhance the...
Web services composition's efficiency strongly depends on the composability paradigm. In this paper, we propose a composability model for Web services that defines a set of composability rules and captures all information needed to verify the interconnection of services. Our proposal essentially deals with functional, non-functional and technical aspects, at both syntactic and semantic levels. It's...
