Abstract Systems-of-Systems (SoS) combine heterogeneous, independent systems to offer complex functionalities for highly dynamic smart applications. Besides their architecture with continuous changes at runtime, SoS should be reliable and work without interrupting operation no failures that could cause accidents or losses. architectural design facilitate the prediction of impact potential due behavior. However, existing approaches do not support such evaluation. Hence, these have been...

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 the validation different operational scenarios in controlled environment, allowing benchmarking its response as well revealing possible breaches that could lead failures. However, traditionally manual, demanding...

Software-intensive systems have become increasingly large and complex new techniques methodologies are necessary to deal with such complexity. Model-Driven Development (MDD) has been used scenarios, since software models, despite details, facilitate the visualization of whole. Moreover, MDD widely recognized as a way assure quality, reducing time effort, making possible automatic transformation models generate source code. In this direction, software-intensive Systems-of-Systems (SoS) is...

Context: Brazil is among the most influential global poultry meat production countries. Occupying second place world’s largest producers, first in export ranking. Hence, to meet high demand, market depends on productivity and performance of birds produced. Problem: As a tropical country, faces difficulties due birds’ sensitivity fluctuations environmental factors, such as temperature relative humidity. These other factors can lead loss low profitability. Proposed Solution: This paper...

Context: The adoption of digital technologies in the health domain can optimize data collection and storage processes, especially context fieldwork carried out by Community Health Agents (CHA). Among pathologies monitored, mouth cancer is one them that, if detected early, improve patient’s prognosis. Problem: When analyzing situation Brazil, we notice an information gap state art regarding Information Systems (IS) specifically designed for use CHAs collecting from patients at high risk...

Context: Data integration is a fundamental activity for achieving full interoperability between Information Systems (IS). One of the most critical steps in this process schema matching, which involves identifying correspondences elements to ensure that equivalent information correctly associated. Problem: The matching can be extremely time-consuming, expensive, repetitive, labor-intensive, and error-prone, potentially leading significant losses. In context, companies employ tools support or...

Healthcare is a data-intensive domain, once considerable amount of data daily produced due to monitoring patients, managing identities, producing medical records and processing insurance claims. Hence, security, besides other quality requirements, prominent preserve the confidentiality integrity such data.
