The ability to control engineering process execution is of vital importance for the success of an engineering project. Thus many studies have been focusing on capitalizing knowledge and practices of systems engineering processes. We proposed in a former work a complete solution (SysPEM: System Process Engineering Metamodel) to this problem starting from the engineering process models to process orchestration...
Nowadays, because of the increasing complexity of systems and projects, more and more people focus on the systems of systems. At the same time, Systems Engineering and Project Management are considered as two independent activities during the development of systems of systems, but many inconsistencies appear between Systems Engineering and Project Management teams during engineering projects although...
The efficiency of software engineering processes is highly dependent on the level of coordination and collaboration inside the engineering teams. Even though the serious efforts to standardize and capitalize practices in order to enhance software engineering processes, we are still in need of a more efficient way to manage concurrent and collaborative engineering. This problem became more obvious...
Consistency between the different views of a systems engineering process is of vital importance to the industry. It guarantees high-level coordination between the different actors and the absence of compromised data and inaccurate information.
Product Lifecycle Management (PLM) tools are widely used by the industry. However, they are not sufficient to guarantee the success of projects and too many projects still fail. Industrial groups have argued that these failures may be related to the managerial techniques used. Indeed organizational processes are more or less specifically mentioned in Systems Engineering (SE) standards but in practice...
Considering that system design becomes more and more complex to manage, systems engineering standards are useful and necessary for the companies. In order to choose the right standard, this paper presents an analysis of and a detailed comparison between the current releases of the main Systems Engineering standards in system design industry, ANSI/EIA-632, ISO/IEC-15288 and IEEE-1220, and illustrates...
Activities and products are among the key concepts defining and participating to the life cycle of software engineering processes. These two concepts are bonded by strong relationships of production and consumption, which implies that their evolution should be monitored to ensure their consistency and coherence, this monitoring is referred to as synchronization between products and activities. In...
Complex systems are designed using set of norms, like EIA-632, IEEE-15288. The requirement traceability is one of the suggested activities to carry out during product life cycle. Currently, most of the requirement traceability processes are defined for software intensive systems. However, it is not specified how to carry out requirement traceability for non-software intensive systems or complex systems...
The Software Process Engineering Metamodel (SPEM) is used to define and describe software development processes and their components. This metamodel contains three main entities: roles, activities and products. Our goal is to ensure synchronization between activities and products of a software development process in order that one of the two entities will be notified and adapted in accordance with...
Mastering the development processes is a major challenge for companies, given the increasing complexity of systems and technological development of this field. Besides roles, a development process consists of a set of activities and products which are interdependent. This mutual dependency between the two entities implies that if one of them undergoes a change or an evolution, the other must also...
In the paper a prescriptive approach to understand customer needs is proposed, which helps to transform the subjective, human-centric problem into a more objective, decision-making problem. By recognizing the diversity of levels or granularities of initially identified customer statements, techniques of fundamental objectives hierarchy and means-ends objectives network are utilized to qualitatively...
This paper describes a teaching experiment where students have to design a telecom system based on a wireless sensor network which specifications are power-oriented. Priority is given to an experimental hands-on approach.
Process-control systems are usually real time and embedded within the larger environment. Controllers are required to ensure desired environment properties through performing ongoing control behavior at the interface with sensors and actuators. However, the environment is heterogeneous and informal, which poses special challenge to develop complete and safe specification. Problem Frames are a rigor...
Limited spatial resolution of positron emission tomography (PET) affects the quality of quantitative measurements. This difficulty can be overcome by the accurate spatial superimposition of magnetic resonance imaging (MRI) and anatomical data bases. This paper deals mainly with the first step of this superimposition process. We describe an entirely automatic 3D analysis of brain MRI data which first...
