Based on systems engineering principles, information modelling is seen as a central activity for the development and life cycle support of a product or system. It enables to reduce the costs derived from miscommunications and misconceptions normally occurring throughout the service system design, analysis and maintenance activities. Supporting the servitization of manufacturing and the evolution towards...
The evolution of businesses, driven by the advent of the internet and subsequent globalisation, was very quick and sudden. Enterprises that had traditional development strategies and that were used to slow changes are suddenly feeling the urge to evolve or face obsolescence. This fast-paced evolution frequently leads to mistakes and erroneous decisions, many of which are solely detected after a long...
The concept of interoperation between cloud providers is a recent research challenging objective. Current cloud systems have been developed without concerns of seamless cloud interconnection, and actually they do not support intercloud interoperability. The paper proposes a conceptual model for Intercloud Interoperability, to enable schedule dynamic operation for Infrastructure as a Service (IaaS)...
A system's requirements and its architecture are usually developed at least partly in parallel. This demands a continuous and automated assessment to confirm that the architecture conforms to its requirements. To enable such an assessment, the stepwise formalization of informal requirements has been proposed. However, there is no canonical set of artifacts and analysis techniques that has been evaluated...
Developing and evolving critical information systems in order to cope with changes in regulations and laws is a constant worry for governments in the e-Government era. Due to the frequent challenges and some previous frustrating experiences, the Brazilian Government has searched for an alternative development method that could better fit its needs. At the same time, Brazilian Academia, represented...
Model-driven engineering is constantly gaining importance, expanding to domains varying from the Web to the 3D graphics. Domain-specific languages besides contributing to the development process can be used in a didactic process conducted not only in schools. Thus this paper introduces new domain-specific language and discusses its usage in teaching construction of shaders and materials while working...
We focus on MDE tools generating source code, entire or partial, providing a basis for programmers to introduce custom system refinements and extensions. The latter may introduce two maintenance issues once code is freely edited: (i) if source tags are affected model reconstruction is broken; and (ii) code inserted without special tags is overwritten on regeneration. Additionally, little progress...
