Research On Safety Evaluation And Safety Investment Of Construction Enterprises

For a long time,the construction enterprises have always had the characteristics of high accident rate and high degree of death toll.Most construction enterprises due to inadequate investment in safety,investment in the wrong direction or the input method is uncertain and other factors,resulting in a touchdown on the basis of safety production,the accident occurred again and again,the cost of waste,such as the status quo.In order to improve the enthusiasm of construction companies to invest in safety,improve the safety status of construction enterprises,reduce accidents and reduce the rate of casualties,the most basic and effective way is to rely on scientific methods of investment in safety and advanced management techniques for construction companies to manage.Therefore,this study of construction enterprises in the safety of investment on all types of economic and personnel losses have very important practical significance.A reasonable increase in safety investment is one of the effective ways to prevent adverse events.Under the condition of ensuring safety,the research on the impact of each index of safety investment on accident loss as well as the characteristics and existing problems of safety management,analyzing its characteristics and conditions,so as to minimize the loss caused by the accident,which is also the construction The necessary choices that businesses need to face.This paper evaluates the safety management of construction enterprises by using BP neural network,finds out 26 input indicators that affect the frequent accidents and 5 output indicators that can summarize the major types of accidents.Then with MATLAB software analysis,we can draw the level of the accident.The trained network is applied to the construction site safety evaluation to provide a reference for the on-site safety assessment of construction enterprises,and at the same time it can also guide the safety management work and safety investment direction at the construction site.This article focuses on the analysis of the construction investment in the construction industry and the main components of the type of accident occurred to find out the main inputs of the safety investment and research methods using gray correlation analysis and calculation of the data obtained in a certain funding conditions Situation,safety inputs on the impact of the safety input of the order of magnitude: labor protection> safety education> safety facilities>civilized construction> safety management.The size of the order can optimize theallocation of funds and the direction of safety inputs,so as to make reasonable investment in safety,reduce the occurrence of accidents,economic losses and casualties.
