Study On The Cause Of Production Safety Accidents Based On Complex Networks

At present,our country is still in the stage of frequent accidents in production safety,and the situation of safety in production is still severe and complicated.This paper studies the accident cause model,and understands the application of accident model and accident analysis method in accidents.In order to prevent and reduce the occurrence of accidents,domestic and foreign scholars put forward a series of' methods in accident model,cause analysis,risk analysis and achieved certain results.However,the construction of the safety system,which is typical of the social-technical complex system,is still in its initial stage,and the hazard identification of the human,material,environmental and management links of the accident is still in its infancy.The study of risk formation mechanism and conduction law of hazard source and operation system is very limited.In this paper,based on the basic data material of production safety accident in Daxing District of Beijing in recent ten years,the theory of complex network is used.The production safety accidents and all the causes in Daxing District are regarded as a complex system.The factors leading to the accidents are analyzed from the point of view of the system,and the key factors leading to the accidents are found out,which provides guidance for the prevention of accidents in advance.The thesis is divided into four parts.The first part introduces the accident model,cause analysis,risk analysis and research of domestic and foreign scholars.The second part mainly introduces the overview of complex network,the research content of complex network.The third part is the statistics and cause analysis of production safety accidents in Daxing District in the past ten years.First,the concept of production safety accidents is defined,and secondly,According to the accident industry,accident category and other analysis to clarify the characteristics of the data,again through the human-material-ring-management four elements of the height of fall and other 10 accident categories of combing and analysis,It is found that each element can be further decomposed into more specific accident cause factors.These sub-accident factors under the four major factors interact and influence each other to make the accident happen.4th part is to establish a complex network.Causative model.Risk chain based on accident type,The complex network of Daxing District is constructed by combing the human,material,loop and pipe factors and each sub-factor of each level as the nodes of the complex network.Part 5th is based on the nodal degree of the complex network.This paper studies the key factors affecting production safety accidents in Daxing District of Beijing with the statistical characteristics such as clustering coefficient.Aiming at the key factors of production safety accidents,the risk control strategy is put forward.
