چکیده
Abstract Cyber-physical systems are hybrid networked cyber and engineered physical elements that record data (e.g. using sensors), analyse them connected services, influence processes interact with human actors multi-channel interfaces. Examples of CPS interacting humans in industrial production environments the so-called cyber-physical (CPPS), where operators supervise machines, according to human-in-the-loop paradigm. In this scenario, research challenges for implementing CPPS resilience, promptly reacting faults, concern: (i) complex structure CPPS, which cannot be addressed as a monolithic system, but dynamic ecosystem single influencing each other; (ii) volume, velocity variety (Big Data) on resilience is based, call novel methods techniques ensure recovery procedures; (iii) involvement factors these systems. paper, we address design resilient (R-CPPS) digital factories by facing challenges. Specifically, component R-CPPS modelled smart machine , is, system equipped set Sensor Data API used collect sensor acquired from side monitoring behaviour, an operator interface displaying detected anomalous conditions notifying necessary actions on-field operators. A context-based mediator at shop floor level, charge ensuring gathering selecting proper invoking corresponding services target CPS. Finally, summarisation relevance evaluation supporting identification presence high volume collected through API. The approach validated food industry real case study.

متن کاملResilience through Learning in Multi-Agent Cyber-Physical Systems
The paper contributes to the design of secure and resilient supervisory Cyber-Physical Systems (CPS) through learning. The reported approach involves the inclusion of learning modules in each of the supervised agents, and considers a scenario where the system’s coordinator privately transmits to individual agents their action plans in the form of symbolic strings. Each agent’s plans belong in s...
متن کاملTowards a Cyber-Physical Resilience Framework for Smart Grids
As modern power grids move towards becoming a smart grid, there is an increasing reliance on the data that is transmitted and processed by ICT systems. This reliance introduces new digital attack vectors. Many of the proposed approaches that aim to address this problem largely focus on applying well-known ICT security solutions. However, what is needed are approaches that meet the complex conce...
