Property-Based Modulable Timing Analysis and Optimization for Complex Cyber-Physical Real-Time Systems

Project description

Optimising cyber-physical real-time systems

In recent years, cyber-physical real-time systems have been playing an increasing role as information processing systems. But this requires functional and timing correctness as well as interactions with the physical world. There is also a need for safe bounds of deterministic and or probabilistic timing properties because of their interaction with the physical world. Unfortunately, they are lacking in terms of their timing analysis. The EU-funded project PropRT aims to combat this lack of optimisation. Specifically, it will explore the usability of developing and constructing timing analysis for complex cyber-physical real-time systems; this timing analysis will be focused on optimised safe and efficient analysis.

Objective

Cyber-physical real-time systems are information processing systems that require both functional as well as timing correctness and have interactions with the physical world. Since time naturally progresses in the physical world, safe bounds of deterministic or probabilistic timing properties are required. PropRT will explore the possibilities to construct timing analysis for complex cyber-physical real-time systems from formal properties. The target properties should be modular so that safe and tight analysis as well as optimization can be performed (semi-)automatically. New, mathematical, modulable, and fundamental properties for property-based (schedulability) timing analyses and scheduling optimizations are needed to capture the pivotal properties of cyber-physical real-time systems, and thus enable mathematical and algorithmic research on the topic. Different flexibility and tradeoff options to achieve real-time guarantees should be provided in a modularized manner to enable tradeoffs between execution efficiency and timing predictability. The success of this project will provide a comprehensive view of the landscape of design, analysis, and optimization options for timing properties in cyber-physical real-time systems. Advanced optimization and analytical frameworks based on the formal properties of scheduling algorithms and schedulability analysis will serve as new ingredients for designing predictable cyber-physical systems, which will trigger a revolution of computer architectures, system modeling, communication mechanisms, and synchronization designs in the near future. The results will bring a new design process to further allow control designers and system integrators in cyber-physical real-time systems to jointly explore different configurations of controllers, computation, and communication parameters for designing timing predictable cyber-physical system applications.
