Electricity represents the engine of contemporary society, but as demand continues to increase, production systems and distribution of electricity are becoming increasingly complex, vulnerable to various risks, which may cause a chain reaction, affecting the final consumer, related systems or even energy security of states. The subject of this paper is risk assessment in the critical infrastructure...
For survival, a living agent (e.g., human in Fig. 1(a)) must have the ability to assess risk (1) by temporally anticipating accidents before they occur (Fig. 1(b)), and (2) by spatially localizing risky regions (Fig. 1(c)) in the environment to move away from threats. In this paper, we take an agent-centric approach to study the accident anticipation and risky region localization tasks. We propose...
In the paper, important functions of the “Safety management system” are considered in the part of the timely identification of dangers and vulnerabilities. Putting in operation such systems in transportation enterprises will increase their performance safety.
Road transport of the oversized loads is a very specific means of transport which requires good organizational skills and specific knowledge of legislation regulating these kind of services. The specificity, is based on the size of structural elements, equipment or machines that require special and individual approach. Proper selection of the means of transport in relation to the load being transported...
Has elaborated economically-mathematical model of assessing the production risk associated with occupational injuries, based on the Mamdani's fuzzy inference method. The model includes assessment of risk associated with workers' safety and the risk assessment of the production profitability reducing due to occupational injuries. The practical application of the model can improve the effectiveness...
Electricity is unique among energy sources in that its use is virtually ubiquitous in everyday life, yet it also has the potential to be instantly fatal when contacted. Due to its familiarity and commonplace use, people are often complacent about electrical hazards and underestimate the risks associated with exposure to electricity. Many veterans in the electrical industry came of age in an era when...
Electrical incidents provide a good learning opportunity. If an organization fails to capitalize on this opportunity, the incident could recur. An abundance of literature is available on the investigation process and various investigation techniques. There appears to be limited guidance on determining the effectiveness of the application of the investigation process after the investigation is complete...
The emerging global energy internet will connect major metropolitan cities together in the world. The power grid risk assessment of these big cities is very important and essential in securing the electrical energy system. In this paper, we propose a fuzzy comprehensive evaluation methodology to quantitatively assess the risks of a metropolitan city power grid system. A 2-level index and weight of...
In this paper, the engineering practical method of risk probability is studied based on the fault probability of the main equipment through setting equipment factor and outage factor. The risk hazard assessment method for network planning is studied based on ACT No. 599 through setting social influence factor and loss load factor. The risk assessment result can receive based risk probability assessment...
International Standards on lightning protection risk assessment (IEC 62305-2: 2010) are well accepted and applied in many parts of the world. During the last few years a large number of lightning related accidents, especially due to direct strikes, have been reported from Asia and Africa where the lightning struck objects are small structures. Information gathered from several investigations done...
This paper presents a human reliability analysis method based on cognitive process model. Human cognitive processes are modelled in different forms under different risk scenarios respectively. The cognitive process model consists of an event tree based on human cognitive process and Bayesian networks modelling the cognitive phases. The Bayesian networks (combining with evidence theory) use hierarchical...
Risk management plays an important role in automobile insurance. Risk classification is the first step in risk management. In order to classify the risk levels of the insured, we provide Analytic hierarchy process(AHP) to identify the risks. Firstly risk factors of automobile accidents are identified according to the theories of accident causation. Then AHP is used to calculate the weighs of risk...
Bonus-malus system (BMS) in motor vehicle insurance is an incentive system to encourage people to drive more carefully. At present, the transfer rule of BMS is related to claim numbers only and it is unfair for the insureds with small claim amounts. In order to establish a scientific Bonus-malus system, we provide hazard identification method to optimize it. By analyzing risk factors of motor vehicle...
Risk management for large and complex networks(e.g. supply chains) is difficult since there are often numerousvulnerabilities and the impact of a disruption is hard to predict. The strive for increased effectiveness often increases complexityand vulnerability rendering it even harder to foresee disruptionsand their effects. Methods and tools that can be used for reasoningabout risks and counter-measures...
This paper presents a safety risk management model based on possibility theory to adapt and develop the Safety Management System (SMS) in airline operation control. Fuzzy sets are used to represent the key elements among crew, meteorology, weight and balance, dispatch, coordinate, and systematic operation control by risk indicators. A fuzzy integrated judgment model is also proposed, which would quantity...
Except traditional clinical risk, hospitals face increasingly number of hazards threatening their daily operation, including natural disasters, public health crisis, and societal security incidents etc. To promote the ability of hazard prevention and emergency response, hospitals need to take measures in risk assessment and risk management, the first step of which is risk factors identification. Here...
Risk assessment is a tool to help drive informed decision making regarding the implementation of hazard-control measures. This paper examines the limitations of quantitative risk assessment. The paper explores factors that can lead to inaccurate or ineffective risk assessments, including faulty probability estimates, failure to adequately account for human factors, and failure to account for all possible...

Batik Merak Manis Laweyan is one of the batik industry in Surakarta, where in the production process there are the potential accidents. The company also has provided personal protective equipment to workers to minimize the risk, but in reality, not all workers use personal protective equipment. The purpose of this study was to analyze the potential hazards that may occur and determine root causes...
