Investigating Quality Trade-offs in Open Source Critical Embedded Systems

2015

During the development of Critical Embedded Systems (CES), quality attributes that are critical for them (e.g., correctness, security, etc.) must be guaranteed. However, this often leads to complex quality trade-offs, since non-critical qualities (e.g., reusability, …

Two perspectives on reference architecture sustainability

2017

In the context of software architectures, sustainability has been investigated as an important quality property to assess how well these architectures support changes over time. Several initiatives to achieve sustainable software architectures/systems can be already …

Stimuli-SoS: a model-based approach to derive stimuli generators for simulations of systems-of-systems software architectures

2017 · Journal of the Brazilian Computer Society

Systems-of-systems (SoS) are alliances of independent and interoperable software-intensive systems. SoS often support critical domains, being required to exhibit a reliable operation, specially because people’s safety relies on their services. In this direction, simulations enable …

Technical Debt Management Automation: State of the Art and Future Perspectives

2023 · arXiv (Cornell University)

Context: Technical debt (TD) refers to non-optimal decisions made in software projects that may lead to short-term benefits, but potentially harm the system’s maintenance in the long-term. Technical debt management (TDM) refers to a set …
