Systems are becoming ever more complex and the practice of systems engineering is becoming more formalized. However, this formalization is aimed primarily at the technical and process components of complex systems and systems of systems. National cultural variations in the human components of such systems (typically functioning as groups or teams) are not typically included in the formal specifications...
Safety-critical systems are systems where failures lead to catastrophic results: resulting in loss of life, significant property damage, or damage to the environment. These systems range from aerospace on-board control systems, ground flight control systems, medical devices, nuclear power plants control, automotive systems, military systems, just to name a few. Other information systems are becoming...
Mixed traffic denotes the coexistence of two driving styles: human and automated driving. Until now, there has been an ambiguity about the driver's safety in mixed traffic. Traffic safety studies focus on a synthesis of control laws which help drivers to avoid or mitigate collisions. Classic safety descriptors use only the time to collision, a time criterion for safety assessment. Other assess traffic...
The human factors involved in an unmanned aerial system (UAS) come in a variety of forms that has largely gone poorly represented in literature. In this paper, a holistic approach is taken to identify not only the individual aspects but the interconnection of the human-UAS interaction. First, an examination of human factors involved in a UAS are presented. Next, the metrics of human performance, such...
In order to control the key point of accidents during bridge construction, a number of major risk factors are recognized from the point of the insecure elements of human beings and the insecure status of objects, and a risk assessment index system of bridge construction stage is created based on these risk factors; so given the uncertainty and fuzziness of the risk factors, the risk assessment of...
The paper is devoted to the safety of complex technical systems of systems (SoS) through the improvement of engineering processes at all system lifecycle stages. The safety of complex technical facilities (such as nuclear and conventional power plants, offshore oil and gas platforms and chemical processing plants) is analyzed based on the systems theory and SoS engineering. The safety concept discussed...
From the fact that human behavior is determined by both miners' intrinsic characteristics and external environment, the factors that may affect human behavior safety in metal underground mining are analyzed. Based on the analysis, countermeasures such as choose eligible miners and optimize environment are proposed, consequently to minimize the adverse effect and maximize the efficiency of miners matching...
The highway infrastructure traffic safety performance evaluation is unstable and unreliable based on the traffic accident number or rate directly as well as other non-accident method. The principle of traffic accident spatial distribution along a highway and correlation between highway traffic safety performance and accidents positions for a period of time were researched. An accident aggregation...
According to situation of ITS application to improve road traffic safety in foreign countries, the necessity to develop ITS in Chinese road safety management is analyzed. On the mechanism analysis of ITS application to promote road traffic safety, ITS technologies were list in three aspects, policy suggestions and promotion strategy were put forward according with national situation to solve issues...
The speed quick, the large volume of traffic highway has provided good convenient for the vehicles journey, but some especially heavy big accidents bring the life and property safety serious threat, the analysis on to the highway safe influence factors, pointed out the highway movement security is by essential factor constitutions and so on the human, vehicle, road, environment and management, analysis...
Reason's (1990) “Swiss cheese” model of human error integrates the human error perspectives into a single unified framework. The original description of his modal was geared toward academicians rather than practitioners. The Human Factors Analysis and Classification System, HFACS (Douglas A. Wiegmann and Scott A. Shappell, 2003) was specifically developed to define the latent and active failure implicated...
It is becoming important to establish methodologies to reduce the possibility of human over-trust in automation. However, there are confusions on the notion of “over-trust.” Even though there are lots of researches on model of human trust in automation, the relationship between trust and over-trust has been hardly discussed. This paper proposes a model of trust in automation which can be utilized...
Human errors which have been affecting safety accidents are one of the main reasons in coal mine. So these Accidents can be pre vented and reduced through analyzing human errors affecting factors. This paper has made elaborate analysis of the relative affecting factors which cause human errors through applying the Gray Relational Theory in coal mine accidents. Based upon this specific analysis, by...
In this paper, a new methodology, which integrates human factors analysis and classification system (HFACS) with Bayesian Network (BN), is proposed to assess the contribution of human and organizational factors in maritime accidents. As a means of making up the lack of quantitative analysis within HFACS, the integration of BN and fuzzy analytical hierarchy process (AHP) have been selected to estimate...
Accident is originated by hidden danger. Discovering and removing hidden dangers is one main approach to prevent and control accidents. This paper collected and analyzed the information of hidden dangers from multiple coal mines. On that basis, we put forward concepts of hidden danger information and standard database of hidden danger information, introduced the structure and build flow chart of standard...
Human, machines and environment, three main factors contained in transport system in coal mines, and their impact on transport accident have been analyzed with system engineering theory of man-machine-environment in this article. Reasons and control of human mistakes, relationship between human and transport accident, analysis of machines' stability and fuzzy comprehensive evaluation have been deeply...
Regional environmental risk assessment and management mainly focused on middle-scale. By analyzing the formation mechanism of regional environmental risk, the scale and intensity of regional environmental risk can be assessed on the base of superposing different risks, which can provide technical support to make decisions for regional environmental risk management. Considering the relationship between...
In order to analysis the mechanism of accidents in shipping industry, the SHEL model is introduced. The relationship among the major elements in the ship's safety management system can be clearly described by this model, and human is regarded as the most important factor in improving the safety of ship. Based on the research work of Shanghai Maritime University, the fallibilities of seafarers are...
In recent years, the problem of the frequent accidents in the SMEs has been a community-wide focus, which is rooted in the market failure caused by the seriously underestimated of the value of human life, Thus leading to the SME owners' lack of power and pressure in safety input. So assessing the value of human life is of great significant, also is a basic perspective for analysis of production safety...
