Railway switches operate in harsh environmental conditions; still, their reliability requirements are high due to safety and economic factors. Once deployed, their maintenance depends on the data collected on their status, and the decisions on due corrective actions. The more regular this data collection and decision cycle is, the better confidence...
Conference Paper
Non-functional requirements are the main drivers behind the design choices that shape a software architecture. Self-adaptive systems blur the boundary between design-time and run-time allowing the dynamic re-shaping of a running system to better accommodate changes in the execution context or in stakeholders' expectations. When these expectations a...

The Agile paradigm, as intended in the 2001 “Agile Manifesto,” brought a disruptive software development methodology. However, with regard to mission- and security-critical organizations, traditional Agile methodologies are quite ineffective because they do not clearly address issues of (1) quality and (2) security. Within the Italian Army General...
Conference Paper
In this paper we present an approach to add self-adaptive features to software systems not initially designed to be self-adaptive. Rapid changes in users needs, available resources, and types of system faults are everyday concerns in operating complex systems. The ability to face these issues in a (semi-)automatic fashion is a welcome feature. MAPE...
Conference Paper
Today’s software systems increasingly work in changing environments, where rapid modifications in user needs, resource variabilities and system faults require remarkable administrative efforts. In order to mitigate the costs for governing these activities, software systems are expected to dynamically self-adapt. The problem of supporting auto-adapt...

Conference Paper
Agile methods are now a mainstream production process and their proponents are no longer considered hackers or cowboy coders. Still, in embedded and safety critical domains there is somehow the expectation that the approach be "more" plan-based; at least, many of the current normatives seem to lean toward such approach. A definite change in attitud...
