Establishment And Application Of Occupational Health Expenditure Input-output Model In Iron And Steel Enterprise

Objectives The aim of this study is to build occupational health input-output prediction model of iron and steel enterprise in order to provide a clear idea for the adjustment of the structure of occupational health investment in iron and steel enterprises.Methods 1 The classification of the occupational health funds of the iron and steel enterprise were invested,the table needed to analyze DEA efficiency and establish inputoutput model of enterprise overall and each branch were formed,and the DEA model and input-output table and model were established.2 The detailed data of the input and output of each branch in a steel enterprise in 2015 were collected and the input and output efficiency of occupational health in each branch were evaluated through DEA method.As for branches that were not optimal efficiency,data were put into the DEA model and a list of relevant parameters calculation and adjustment scheme were obtained,and occupational health input and output data after adjustment and other relevant data were substituted into it to build prediction model.Results 1 According to the characteristics of the iron and steel enterprise's occupational health,occupational health funds input-output table have been established,which can reflect the input and output relationship among various departments(workshops)directly and clearly.2 In the branches of the iron and steel enterprise,the occupational health input output efficiency score of stainless steel plant and smoothers was the highest,equal to 1,while the cold rolling plant had the lowest,equal to 0.759.3 In the cold rolling plant,only acid rolling workshop parameters met the standard of ?=1,s-=0,s+=0.And the remaining four workshop could reach at 1.7044,2.0238,1.3152 and 1.2136 times respectively after adjusting each component according to the parameter.The input and output model of the cold rolling mill was built.4 The adjusted data were put into the occupational input-output table and the prediction model was built.The coefficients ? was a 17 order matrix,by which,the occupational health input can be calculated through annual production plan.According to the investigation of the various branches of the planned output value in 2016,the total occupational input of each plant and various input of workshops are given in the table.Conclusions 1 According to the characteristics of occupational health of iron and steel enterprises,the specific input and output table and forecast model are built.2 In the iron and steel enterprise,the occupational health input of the stainless steel plant and some others have the largest output,while the cold rolling plant have the worst situation.In the cold rolling plant,only input components of acid rolling workshop have the largest output while the logistics workshop havethe worst situation.3 In the input-output prediction model of the cold rolling mill,? is a 17 order matrix,which connects the final product of the factory with occupational health investment,total output value and energy consumption.If the estimated annual output of a given year is known,after being converted to the total output value,the most suitable occupational health input and the largest occupational health output can be calculated.
