The extension method based on entropy weight is a new safety evaluation method. Entropy weight, which is an objective weight, was ascertained by entropy theory. As a result, the subjectivity in ascertaining the weights of more factors in lower hierarchy was avoided. The comprehensive correlative degree was taken as the evaluation criteria in this method. Therefore the subjectivity of evaluation model...
This paper firstly gives a construction safety evaluation system based on previously researches. Secondly, it gives the concept of intuitionistic fuzzy sets concisely. Then, intuitionistic fuzzy TOPSIS method is introduced. Finally, a numerical example for safety evaluation is given to illustrate application of the method.
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...
Coal mines safety condition decides the economic condition of the regional development on one hand, more importantly the safety of employees working for mines on the other. This article has introduced a scientific system to evaluate the safety level of coal mine based on AHP so as to give out significant information for the managers of coal mine to make and implement corresponding polices concerning...
In order to improve the reliability of chemical equipments operation, the simulation research on the reliability of the operators is needed. Basing on the research platform of Dalian Chemical Industry Group Corporation (The Group), taking the reliability model of Human Cognition Reliability (HCR) as guide, in allusion to the 17 abnormal events which affect the running safety, the allowable operation...
The occurrence of accident be understood as mutations in a qualitative change caused by a continuous change of some of the parameters within the system. The system from security state into the state is actually a mutation phenomenon. The paper applies the Catastrophe theory and system analysis method of the accident causation, establishes the spire catastrophe model. By analysing the model, indicates...
The development in this work is to evaluate analytically human-robot system for collaboration based on performance requirements in cellular manufacturing system. This work continues from a previous task modeling study to further evaluate quantitatively the collaboration planning of the human-robot system. The analysis study is based on Analytic Hierarchy Process (AHP) approach. Four criteria (productivity,...
This article gives analysis on industrial products from the angle of human safety. It points out that, as the medium between human beings and the outside world, industrial product plays an important role in the inevitable activities human beings taking part in. So, the research in the safety of industrial product design becomes necessary. The article discusses the direction of safety in product design...
Vibration seems to be the most critical Ergonomics Risk Factors (ERF) in Malaysian industries. In order to quantify and determine the safe levels of human exposure to vibration, measurements and analysis of vibrations are therefore necessary. The aim of the study is to identify the effect of hand-held vibrating tools on significant muscles. The study was conducted on seven subjects (three male and...
Safety culture is a social control power in hazardous industrial systems. This study aims to explore the characteristics of safety culture in China. The 128 behavior incidents of employees' routine work were gained through 103 days' participant observation in a state owned petrochemical plant. Cluster analysis was conducted on the selected 109 incidents, and finally assembling them into 4 categories...
Mine hoisting accidents, as common and frequent disasters, the statistics shows 90% of them are caused by human errors. Therefore, studying human reliability of the systems can effectively reduce systems failure due to human errors. Although the significance of human reliability has been widely acknowledged, this technology, currently restricted to aerospace, aviation, nuclear industry, is not prevalent...
Coal mine safety evaluation analyses mine's existent dangerous and harmful factors, and judges mine's potential risks. The evaluation result is propitious to guard against accidents and make management decisions. This paper analyses all kinds of influence elements on coal mine safety, constructs evaluation indexes system, measures weights using AHP, and applies dynamic fuzzy theory in mine safety...
In China, the safety of high falsework is a worrying problem, and human error is the uppermost reason for the collapse of falsework. In this paper, on the bases of test data of axial forces of vertical bars of the falsework in a construction site, a phenomenon of improper erection of vertical bar (IEVB) is described and analyzed. The effect of IEVB on structural reliability is discussed, and the results...
Safety is one of the key problems people concern about most not only at present but also in the future. Currently there are many hidden troubles threatening safety. Particularly, the safety problems in coal mines are very serious and in great need of management and control, because they not only influence humanpsilas increasing demand for energy, but also affect severely environment. Hence, itpsilas...
The objective of this work is to enhance man-machine collaboration in cell production by task modeling approach. Task modeling provides a method to define and study the collaboration between man and machine. Six requirements have been derived as basis of development. In this work, the task modeling has extended classical HTA method to represent collaborative operation in a hierarchical structure with...
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...
This paper demonstrates the necessity of establishing the evaluation system for safety resources based on data of accounting systematically. The author gives the connotations and the features of the proposed new evaluation system of the safety resources. The main viewpoint of the paper includes that evaluation system for safety resources is used in all units with possible accidents in production and...
