The 1st Workshop on vAlidation and verification in FuturE cybeR-physical Systems (WAFERS) will be co-Located with the LADC 2019 Conference (Latin-American Dependable Computing) on November 19th Natal, Brasil.

The goal of the workshop is to provide a common forum where researchers from across the world can debate new research ideas and directions on novel dependability assessment approaches for cyber-physical and complex systems by gathering researchers and practitioners working on cypher-physical research topics and related areas such as data communication in cyber-physical networks, safety and security of cyber-physical and critical systems, automated verification and validation of critical systems.

 

The project kick-off and the first Transfer of Knowledge workshop was held in Florence in the beginning of February 2019. The goal of the workshop was to present the competencies of each partner, and start collecting the new challenges and the requirements of the two industrial case studies. These will serve as a basis for future V&V activities of CPS systems.

The first case study is the Brazilian Environmental Data Collection System (BEDCS) developed and operated at INPE, which is a system to monitor the state of rainforest and oceans. The system consists of more than 800 data collection stations scattered throughout Brazil, satellites collecting the data from the stations, and a data processing and visualization center. The system consists of heterogeneous, dynamic components developed and evolved since the nineties, therefore the V&V of the systems is highly complex and critical. One of the current major challenges is to update the system to a CubeSat-based platform without interruptions in the system operation.

The second use case provided by ResilTech is studying the use of modern, multi-core processors and operating systems in future safety-critical systems. Based on experiences in the automotive, railway and industrial automation domains, currently single-core processors and dedicated operating systems supporting a limited number of devices and sensors are used in safety-critical systems. However, on the one hand due to new CPS application areas, e.g. autonomous driving or intelligent industrial controllers, increased performance and flexibility is needed. On the other hand introducing multi-core processors and more general operating systems pose significant verification and certification challenges. The ADVANCE project will work on V&V techniques applicable in this context and will follow relevant industrial initiatives (e.g. OSADL SIL2LinuxMP).

Bence Graics and Vince Molnár (BME) have started their secondments at INPE in October 2019. Bence Graics is a PhD student and Vince Molnár is an associate researcher at the Budapest University of Technology and Economics. Their main research interests are model-driven development and verification of component-based reactive systems. Vince Molnár also specialized on formal methods to support the verification of large-scale concurrent systems.

During the considered period, Andrea Ceccarelli (CINI-UNIFI) worked with professors Leonardo Montecchi and Eliane Martins, PhD student Lucas Leal and MSc student Elder de Oliveira Rodrigues Júnior. In particular, it should be noted that Andrea Ceccarelli is currently appointed as supervisor of Lucas Leal, who is currently performing a dual PhD Degree with University of Campinas and University of Firenze. Further, Andrea Ceccarelli is expected to supervise Elder during his stay in Firenze, that is planned for six months starting at the end of 2019.
