Abstract

The systems modelling and the assessment of their performances are the two key phases of any reliability or risk analysis study. However, it is well known and admitted that most of the methods devoted to this goal are unsuitable if the physical behaviour of the systems cannot be made independent from the probabilistic behaviour, as is the case for dynamic process systems. To overcome this inefficiency, some alternative methods have recently appeared. But they are not very approachable and could be, for this reason, ignored by most of the practitioners. Among these methods, however, simulation methods should be confirmed. From this point of view, the authors propose a straightforward approach to this problem by using stochastic Petri nets on a simple and well-known dynamic system from the literature. In addition, for testing this approach, the authors have carried it out on a system with periodically tested components. The results obtained are compared to those already published, the limits of the method are underlined and its efficiency in solving this kind of problem is being examined.

Development of a data-driven simulation framework using physics-informed neural network
2023, Annals of Nuclear Energy
Because nuclear power plants (NPPs) are safety–critical systems with large sizes and high complexities, various methods have been developed to identify possible accidents and address potential risks. Accordingly, the probabilistic safety assessment (PSA) methodology is a prevalent nuclear risk assessment methodology. However, PSA has limitation in the consideration of dynamic interactions. As simulation methodologies develop, several simulation-based D-PSA methodologies have been developed, but there is a problem that the calculation speed and interaction of simulation cannot be considered.
We propose a physics informed neural network (PINN) based data-driven simulation framework. The simulation framework comprises solution and model generators. The solution generator performs as the existing physical process model by using initial conditions, and boundary conditions. The model generator configures the most representative equation by using measurement data. Therefore, by sing the proposed framework, it is possible to construct a simulation methodology that not only has a fast simulation speed, but can also easily reflect system interactions.
Collision hazard modeling and analysis in a multi-mobile robots system transportation task with STPA and SPN
2023, Reliability Engineering and System Safety
This paper investigates the ability to use complex multi-mobile robotic systems in risky and dynamic environments, such as industrial plants and laboratories, with the presence of the human factor. More specifically, it presents an approach to analyze the dominant risk, extract, model and quantify the hazard scenarios, then propose requirements using the combination between two methods: System Theoretic Process Analysis (STPA) and Stochastic Petri Nets (SPN). This approach is demonstrated with a case study related to a chemical transportation task within a miniature analysis laboratory in oil and gas industry. The main purposes of this article are: to investigate how the risk and safety of these systems should be managed, to create a framework for modeling collision hazard scenarios, further a Monte Carlo simulation is performed to quantify the collision frequency and unavailability. In addition, to generate the required constraints and requirements in order to improve the safe operation of robots within the laboratory.
The novel contribution of this study is to provide a hazard assessment approach suited to multi-controller and autonomous systems while considering coordination between controllers. Hence, the current study proposes a set of safety requirements, which allow designers and programmers to improve autonomy features in mobile robots. The STPA-SPN combination offers better modeling and assessment of robot's performance as well as their hazard frequency.
Supervised dynamic probabilistic risk assessment: Review and comparison of methods
2023, Reliability Engineering and System Safety
With the adoption of autonomous systems in higher levels of autonomy, large-scale, complex and dynamic systems are becoming commonplace. Ensuring safe operation of safety-critical autonomous systems is paramount, typically approached through risk assessment. Two challenges associated with using traditional risk assessment methods for complex systems are that these systems are dynamic (i.e., their state changes over time) and interactions between subsystems and components may lead to unpredictable behaviors and impact on the surrounding environment and other systems in the close vicinity. Dynamic probabilistic risk assessment (DPRA) methods are possible solutions to these challenges, where the dynamic and uncertain nature of the systems is considered. The methods, however, usually face combinatorial explosion related to hazards and scenarios, which make their practical application prohibitive; in the DPRA literature, this problem is known as the state explosion problem. In this paper, we present a literature review on methods for DPRA, with focus on the existing solutions to the state explosion problem. Specifically, we analyze and compare these solutions in terms of computational time complexity, traceability and state–space coverage. Finally, we discuss the comparisons and propose potential paths to improved solutions for the state explosion problem based on the knowledge gained in the study.
Dynamic probabilistic risk assessment (PRA): Theory, tools, and applications for uncertainty quantification
2023, Risk-informed Methods and Applications in Nuclear and Energy Engineering: Modeling, Experimentation, and Validation
The conventional approach to probabilistic risk assessment (PRA) using event and fault trees can at best account for the order of occurrence of events in system evolution. Dynamic PRA (DPRA) methodologies are defined as those that explicitly account for the time element in probabilistic system evolution and allow assessment of the impact of epistemic and aleatory uncertainties on system safety and reliability in a phenomenologically and stochastically consistent manner. DPRA methodologies are usually needed when the system has more than one failure mode, control loops, and/or hardware/process/software/human interaction. A review of major DPRA methodologies proposed to date is presented with current challenges in data generation and analysis and some measures to meet these challenges.
Resilience assessment for nuclear power plants using Petri nets
2022, Annals of Nuclear Energy
Since the resilience issues encountered in nuclear power plants (NPPs) has not been explicitly addressed to date, Petri net models are developed in this paper to simulate the health states of relevant facilities, immediate responses, mitigation processes, and recovery and maintenance processes in an NPP. With the aid of the models developed, the resilience of the NPP is assessed with the consideration of the influence of ageing and the impact of external events. To demonstrate the methodology developed, it is applied to assess the resilience of a single-unit pressurised heavy-water reactor system to a station blackout accident. It has been shown that the methodology developed is effective in simulating and assessing the resilience of the NPP. It is also found that the ageing and proper maintenance of facilities that do not directly affect the operation of nuclear reactors are critical to the resilience of NPPs.
Applications of Bayesian networks and Petri nets in safety, reliability, and risk assessments: A review
2019, Safety Science

It is important to note that only the severity of the hazards is used for safety analysis so the analysis remains qualitative. Dutuit et al. (1997) presented a PN-based approach which included qualitative analysis, i.e. determination of potential sequences of events that lead to system failure as well as reliability analysis with application to distributed processing systems and communication networks in Kumar and Aggarwal (1993), Muppala and Lin (1996) and Balakrishnan and Trivedi (1996), respectively. A tutorial has been provided in Schneeweiss (2001) showing how PNs can be used to model different reliability scenarios.
System safety, reliability and risk analysis are important tasks that are performed throughout the system life-cycle to ensure the dependability of safety-critical systems. Probabilistic risk assessment (PRA) approaches are comprehensive, structured and logical methods widely used for this purpose. PRA approaches include, but not limited to, Fault Tree Analysis (FTA), Failure Mode and Effects Analysis (FMEA), and Event Tree Analysis (ETA). Growing complexity of modern systems and their capability of behaving dynamically make it challenging for classical PRA techniques to analyse such systems accurately. For a comprehensive and accurate analysis of complex systems, different characteristics such as functional dependencies among components, temporal behaviour of systems, multiple failure modes/states for components/systems, and uncertainty in system behaviour and failure data are needed to be considered. Unfortunately, classical approaches are not capable of accounting for these aspects. Bayesian networks (BNs) have gained popularity in risk assessment applications due to their flexible structure and capability of incorporating most of the above mentioned aspects during analysis. Furthermore, BNs have the ability to perform diagnostic analysis. Petri Nets are another formal graphical and mathematical tool capable of modelling and analysing dynamic behaviour of systems. They are also increasingly used for system safety, reliability and risk evaluation. This paper presents a review of the applications of Bayesian networks and Petri nets in system safety, reliability and risk assessments. The review highlights the potential usefulness of the BN and PN based approaches over other classical approaches, and relative strengths and weaknesses in different practical application scenarios.
