Study Of Safety Production Benefit Of Building Project

In recent years, with construction industry developing quickly, the safty is worse and worse.More and more people recognize that safety is a kind of benefits to all the people.As safety benefit has some following characters; indirect,latent,secluded, it can not get desired recognition by some enterprises.In a certain extent it account for more serious safety situation.In this paper, the emphases of safety is precaution, the safety input before and during construction should be taken great attention.And bring forward some methods and ways for safety input, do some research to evaluation of safe management of construction engineering.Firstly this paper introduces the theory of DEA ,which is used to analyze the safety benefits of the same types of department has multiple attributes investments and multiple attributes outputs. Also introduced the principle and application of this theory.Secondly, make further research to safety input, Safety and the relation between input and benefit of construction engineering. Analyzed the influencing factors of benefit and the relationship from safety input to accident loss.At last ,apply the theory of DEA into an example, which is used to analyze the safety benefits of many construction projects.Attempt to find the success and deficiency in the course of development. And the result about these projects'safety efficiency can be guide for decision making units.
