Conceptual modelling is situated in the broader view of information systems requirements engineering. Requirements Engineering (RE) explores the objectives of different stakeholders and the activities carried out by them to meet these objectives in order to derive purposeful system requirements and therefore lead to better quality systems i.e. systems that meet the requirements of their users. ...

Requirements engineering (RE) is concerned with the elicitation of requirements from users (stakeholders), analysis of these requirements and the generation of a coherent specification for downstream software engineering processes. Present-day RE projects typically involve large, diverse and distributed groups of stakeholders, who specify their requirements mostly using informal notation. In th...

This paper presents an overview about a Brazilian research towards requirements engineering process for embedded systems. The scientific contributions reported throughout the paper are concerned to templates, guidelines and tools developed during the last four years. These artifacts can help to narrow the existing gap between hardware and software embedded system teams. We brifely describe two ...

Over a decade ago Service Oriented Architecture (SOA) was introduced to provide better alignment between business requirements and IT solutions. During this period a great deal of research interest has emerged from academia and industry alike, to promote this new style of software development. The promise was that SOA based development will improve reusability, agility, platform independence an...

Requirement analysis, modeling and verification are an important part of the development process. There is a strong need for integrating these aspects into a formalized modeldriven development process, together with a dedicated methodology as well as effective tool-chains. In this context, the paper presents a Modelica-based implementation of an approach for the formal modeling of system proper...

The realization of nuclear fusion reaction as energy source is under investigation, among the scientific community, through design and development tokamak reactors. Among several experiments worldwide, ITER project major international experiment it involves research institutes from countries. In such a project, Systems Engineering (SE) approach requested to organize manage due its highly integr...
