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...
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...
Safety culture is an umbrella term covering related fields, such as human factor analysis, human reliability analysis, and human performance tools. As a whole, the goal is to increase the utilities' ability to handle anticipated as well as unexpected events. Recently, resilience engineering - with much the same goals - has gained popularity in the nuclear industry. In this paper we explore the similarities...
Comparing risks of rare, high consequence events poses serious challenges to social decision making as well as deep methodological and epistemological problems. It is necessary to assess the merits of countermeasures that are only useful in extremely unlikely circumstances. The value of a conventional conditional probability P(A|B)=P(A∩B)/P(B) becomes too uncertain to be useful when P(B) is not well...
This article presents the results of a study on including human factors in assessment of the level of danger involved in a robot operation. A dynamic risk assessment method, which considers all effective factors in a collision, is essential for planning and control of the human-safe robots. In this regard, the visibility of the robot in the human eyes can significantly effect the probability of collision...
According to the high security requirement of rail transit signal system, the paper studied the engineering safety management theory of foreign advanced rail transit signal system, summarized the risk control process of rail transit signal system with the characteristic of china's rail transit signal system and focused on some key issues in the risk control process. Using of ALARP principle as the...
Drinking water safety is an important part in water scientific field. The traditional living drinking-water quality assessment can not evaluate wholly the impacts of groundwater quality on human body. The groundwater health risk assessment is applied to evaluate the quality of groundwater providing to an important city in west of China in this paper. The analysis shows that health risk super standard...
In this article, based on the FIST model, it proposes four parameters to describe the crowd massing risk in public venues that are the density (D), mutual interaction between each others(I), the personnel characteristics (C) and the impact derived form environmental (E) disturbance on the massing crowd. Then, it carries out the corresponding technical analysis for the four predefined parameters. First,...
In the guidance of the thoughts from fire safety engineering and according to the kinetic mechanism of the occurrence and development of fire and the technological principle of fire prevention and control, this paper preliminarily studies the application of fire risk evaluation method in the fire safety engineering of an underground construction. By determining fire security goal, performance criterion...
The challenge of this work is to study the design and development of human-robot collaboration (HRC) in cellular manufacturing. Based on the concept of human collaborative design, four main design factors are being identified and developed in an active HRC prototype production cell for cable harness assembly. Human collaborative design aims to optimize the system design for the advantage of collaboration...
The key challenge of this work is to research the safety design and development of a close range active human-robot collaboration system in which no governing safety standards and regulations are currently present. Active robot assistance in a human-centered cellular manufacturing system is very promising proposal, however safety is the uppermost consideration before this idea can be materialized...
This paper applied the health risk assessment model recommended by the American Environmental Protection Bureau (EPA) , calculation the health risk and analysis the test index about As, Hg, Cr6+, Pb, Cd, F in Ya'an rural drinking water. The result indicates that the average concentration of the pollutants are respectively as follows: As: 0.004 mg/l, Hg: 0.001 mg/1, Cr6+: 0.005-0.015 mg/l, Pb: 0.01...
When considering the issue of electrical safety in product and system design, it is critical to use a well defined design process that complies with the legal standards. Engineers need not be lawyers but they do need to understand how the law views the process of engineering design. For any product or system that brings electrical energy into close proximity with human users, the risk of electrical...
Existing literature suggests that human error is directly linked to the majority of industrial incidents and accidents. The increasing use of computers and software in safety-critical systems makes systems more integrated and dependent and this can increase the risk if barrier integrity is reduced. This paper demonstrates how the Human Factors Assessment and Classification System (HFACS) can be applied...
The authors introduce an activity of a new working group under ISO/TC184/SC2 which is approved to formulate a new international safety standard ldquoRobots and robotic devices - Safety requirements - Non-medical personal care robotrdquo associated with robots that are allowed to coexist in human environments for the purpose of providing humans with various services. The standard includes risk assessment...
Marine accidents were mostly caused by the human errors, and it is important to emphasize the research about the human elements for the safety of ships. Risks based on human organization factor (HOF) associated with the vessel operation system at sea are analyzed according to the elements in this system and a new method of proposed risk assessment(PRA) is developed to ensure safe ship operation including...
Strategic and tactical risk management (STRM) is a risk management tool providing users with a framework to assess, monitor and manage the safety of their systems in the short and long term basis. It consists of 2 levels of analyses: the tactical safety assessment (TSA) and the strategic safety assessment (SSA). The tactical level analysis serves to provide a quantitative assessment of the safety...
This paper offers an assessment of airport internal safety risk. It deals with general concept of risk and safety, describes the main causes of airport risk. A model based on fuzzy simulation technique and hierarchical structure analysis is developed to evaluate the airport internal safety risk. With the use of linguistic terms, subjective assessments of qualitative safety risk indexes are represented...
Risk has always been analyzed according to two parameters, namely, probability of an event and the losses it may cause. Risk is classified into three areas in this paper. The using of probability analysis alone may give rise to some misguidance, and two new parameters are proposed to analyze the disaster risk, namely the cost of safety precautions and losses of the disaster. Without probability analysis,...
The concepts of safety and security are used interchangeably and often inappropriately in defining the characteristics and emerging properties of general and cybernetic systems. This paper provides a clear distinction for the two concepts and further develops a systems framework for the attainment of these highly desirable properties in complex systems. The concepts of safety and security are examined...
