This is the accepted manuscript version of a conference paper which has been published in final form at https://doi.org/10.1109/ICCST49569.2021.9717390Safety engineering and cyber security have complementary aims, but typically realise these using different techniques, risk assessment methods and cultural approaches. As a result, the integration of safety and cyber security concerns is a complex process, with potential for conflict. We present a generalized taxonomy of common conflict areas between safety and cyber security, oriented around the development and deployment lifecycle, and supplement this with a discussion of concepts and methodologies for resolution based on the shared principle of defence-in-depth

Going one step further: towards cognitively enhanced problem-solving teaming agents

Operating current advanced production systems, including Cyber-Physical Systems, often requires profound programming skills and configuration knowledge, creating a disconnect between human cognition and system operations. To address this, we suggest developing cognitive algorithms that can simulate and anticipate teaming partners' cognitive processes, enhancing and smoothing collaboration in problem-solving processes. Our proposed solution entails creating a cognitive system that minimizes human cognitive load and stress by developing models reflecting humans individual problem-solving capabilities and potential cognitive states. Further, we aim to devise algorithms that simulate individual decision processes and virtual bargaining procedures that anticipate actions, adjusting the system’s behavior towards efficient goal-oriented outcomes. Future steps include the development of benchmark sets tailored for specific use cases and human-system interactions. We plan to refine and test algorithms for detecting and inferring cognitive states of human partners. This process requires incorporating theoretical approaches and adapting existing algorithms to simulate and predict human cognitive processes of problem-solving with regards to cognitive states. The objective is to develop cognitive and computational models that enable production systems to become equal team members alongside humans in diverse scenarios, paving the way for more efficient, effective goal-oriented solutions

Modular safety assurance

Most embedded systems in the automotive, avionics, or automation domains are safety-critical systems which are subject to strict safety standards and regulatory guidelines which govern the development process
