Research On Multilevel Information Loss Of The Sharing Process For Safety Information Within Enterprise System Internal

Information loss exists widely in the sharing process of safety information within enterprise system,which makes the subject of safety information unable to obtain and recognize safety information comprehensively,thus the behavior decision of safety information subject is affected,increasing the possibility of the behavior errors,and may further lead to accidents.Therefore,it is of great significance to study the mechanism of information loss in the sharing process of safety information.This paper takes multilevel information loss in the sharing process of safety information as the research object,aiming at the problems such as insufficient research on the internal law of the flow process of safety information sharing,the lack of scientific and reasonable expression method for multilevel information loss process,and the lack of corresponding index system for evaluating multilevel information loss.Based on the research of safety information sharing and its flow loss,the basic stages and key elements in the flow process of safety information sharing were analyzed,and the information loss in each stage of the flow process for safety information was explored.On this basis,a safety information sharing flow model and a safety information flow loss model were constructed.According to the above research,this paper analyzed and defined the multilevel information loss in the sharing process of safety information,constructed the corresponding "ladder hierarchical" model and formal mathematical model.And selected the corresponding accident cases to verify the rationality of the"ladder hierarchical" model and formal mathematical model.At the same time,this paper extracted the main influencing factors of multilevel information loss in the sharing process of safety information,and established the corresponding evaluation system of influencing factors.In order to further analyze the multilevel information loss in sharing process of safety information,based on the above work,this paper conducted questionnaire design and investigation to make each measurement index concrete.And this paper established a confirmatory factor analysis model and an inter-factor causality analysis model.On the basis of questionnaire reliability and validity test,combined with the questionnaire data operation model,the rationality and weight of the four main influencing factors were verified,and the relationship between the main influencing factors was verified.The confirmatory factor analysis shows that:the four main factors have proposed in this paper are reasonable,meanwhile the safety information literacy of the information subject is the most important influencing factor.At the same time,through the inter-factor causality verification,it was found that the safety information environment has a positive influence on the safety information characteristics and safety information literacy,while the safety information characteristics and safety information literacy have a positive influence on the safety information ability.In addition,the safety information environment indirectly affects the safety information ability through the safety information characteristic and the safety information literacy.
