“…FRAM and STAMP are in essence qualitative safety analysis approaches, although in the case of FRAM some quantitative extensions (Patriarca et al, 2017; Patriarca, Falegnami, et al, 2018), including the application of Fuzzy Logic (Hirose & Sawaragi, 2020; Slim & Nadeau, 2020), have been described. STAMP has been extended with system dynamics (Bugalia et al, 2020; Kontogiannis & Malakis, 2012) and model checking tools (Han et al, 2019; Yang et al, 2019). EAST already has a quantitative element built‐in to its framework in the form of network metrics.…”

Collaborative human–machine interaction will be progressively intensified in industrial applications. The aim of this article is to examine current approaches to cobot safety by showing that these approaches can additionally benefit from systems thinking methods. The first part of this article covers a narrative literature review on predominantly techno‐centric robot safety approaches, with a strong focus on containing kinetic energy and ensuring separation with humans. The second part introduces systems thinking methods to analyze a socio‐technical perspective on cobot safety, including joint cognitive systems and distributed cognition perspectives. This explorative research dimension is expected to overcome an overly narrow interpretation of safety issues, anticipating the challenges ahead in ever more complex cobot applications. This article embraces a socio‐technical perspective to explore the potential of Joint Cognitive Systems to manage risk and safety in cobot applications. Three systemic safety analysis approaches are presented and tested with a demonstrator case study concerning their feasibility for cobot applications: System‐Theoretic Accident Model and Processes (STAMP); Functional Resonance Analysis Method (FRAM); and Event Analysis of Systemic Teamwork (EAST). These methods each provide interesting extensions to complement the traditional understanding of risk as required by current and future industrial cobot implementations. The power of systemic methods for safer and more efficient cobot operations lies in revealing the distributed and emergent result from joint actions and overcoming the reductionist view from individual failures or single agent responsibilities. The safe operation of cobot applications can only be achieved through alignment of design, training, and operation of such applications.

STPA-Based Analysis of the Process Involved in Enforcing Road Safety in Austria

The European Commission pursues a strategic action plan using the “Safe System” approach. The function, layout and design of roads shall be coordinated in such a way that human error is compensated, and possible accidents no longer cause fatalities or serious injuries. Four fields of action are defined: people, vehicles, roads and laws. This study aims to model the process involved in road safety management in Austria based on the System-Theoretic Process Analysis (STPA) and to identify areas of improvement that also meet these goals. This is intended to create the basis for a method that can also be applied in practice to meet the “Safe System” approach. The traffic authorities or road owners are responsible for monitoring and enforcing road safety in Austria. Their main instrument is the Road Safety Inspection (RSI) that focuses primarily on road traffic planning aspects. This study proposes a method for including human-road-vehicle interactions in RSI. The STPA-based analysis showed how the road safety management and RSI can be improved to provide more comprehensive, accurate and relevant information about hazards at various levels of the safety management structure. The results can be used for improving the safety of all road users.

“…The need for dynamic risk assessments in SoS is also argued by Aitken et al (2010). An early idea to improving the efficiency and effectiveness of STAMP analysis by using formal methods has been presented by Yang et al (2019).…”

Towards a Unified Approach to System‐of‐Systems Risk Analysis Based on Systems Theory

In systems‐of‐systems (SoS), trustworthiness is a key concern, which includes operational risks such as safety, security, and privacy. These are particularly challenging to achieve in an SoS, due to the shared responsibility among independent constituent systems. This paper investigates a unified approach based on systems thinking for analyzing risks in SoS. Having a common framework is important, since many risk areas are related and affect each other. The paper also discusses how traditional static risk analysis can be complemented by dynamic techniques that collect data over time to fuel SoS evolution with respect to risk reduction.
