A Model-Based Toolchain to Verify Spatial Behavior of Cyber-Physical Systems

Abstract

A method preserving cyber-physical systems to operate safely in a joint physical space is presented. It comprises the model-based development of the control software and simulators for the continuous physical environment as well as proving the models for spatial and real-time properties. The corresponding toolchain is based on the model-based engineering tool Reactive Blocks and the spatial model checker BeSpaceD. The real-time constraints to be kept by the controller are proven using the model checker UPPAAL.

Modelling and Analysing Resilient Cyber-Physical Systems

“…Cyber-physical spaces [13] are composite models integrating human agents, computational and physical aspects of systems. Formal languages such as spatio-temporal logics [14], [15] can be used to describe, verify, and test complex properties where the spatial and temporal part are intrinsically connected and influence each other. Furthermore, they provide efficient monitoring procedures to verify the property and they deal with changes in spatial configuration.…”

On Decision Support for Remote Industrial Facilities using the Collaborative Engineering Framework

“…BeSpaceD is highly scalable; BeSpaceD-based functionality such as services can be offered as cloud-based services using highly scalable infrastructure, but can also run locally on embedded devices that support a Java runtime environment such as Raspberry Pi-based controllers. In addition to the work described in this paper, we have successfully applied BeSpaceD to other application areas such as coverage analysis in the area of mobile devices [34] and for verification of spatiotemporal properties of industrial robots [35], [33], [9].…”
