Research On Risk Early Warning Management Of Railway Engineering Construction Stage That Based On AHP

Along with the development of social economy, traffic in people's lives occupy an increasingly large proportion, people demand for convenient transportation becomes more and more, especially for long distances, for railway traffic convenience demand more exuberant. But with the railway construction project increasingly large scale, its complexity increases, increasing the risk factors on railway engineering project construction stage ah, increased probability of occurrence of the risk, to the construction enterprise and the project participants brought many losses, hinder the smooth progress of the construction, and for most of the construction enterprises, risk awareness is relatively weak, poor risk management, lack of risk on the construction of an early warning of risk management, in an unknown state, more students and personnel loss caused by the railway construction project risk casualties, therefore, the index system on the basis of risk the railway project encountered in the construction phase of construction of a risk warning, risk of construction stage to achieve a warning effect, The project management risk happens to risk have a predictable state, thus the risk occurred ahead of time to do a full preparation, reduce the probability of risk occurrence and reduce the risk of the project resulted in a loss and personnel casualties.First, this article makes a thorough analysis and Research on the railway project and its characteristics, and then carry out the identification and analysis of risk characteristics of the railway engineering project may encounter in the construction phase of the impact of the risk on the construction stage of the railway project from the internal and external factors were classified and analyzed, and the Risk Breakdown Structure stratification of railway engineering project risk factors in construction stage; the second is based on the analysis and Research on the risk of construction stage of the railway project construction of the initial stage risk early-warning index system, the index system of transport in the initial index for attribute reduction in rough set theory were screened, the risk early warning the final index system, and using the AHP analytic hierarchy weighting index of indicator system method, thus obtains the index in the system Important degree, and can be calculated risk by using the weight degree, so as to take corresponding preventive measures; finally, according to the analysis from the level of risk response plan, main risk factors of the program to deal with, on the dynamic risk prevention and control measures and the overall risk control four aspects proposed the risk prevention and control measures.The risk encountered by the railway engineering projects in the construction phase of construct a risk early warning index system, achieve the effect of a risk early warning, in the existing literature research is less, so the study has certain innovation and the latter part of the research has a certain reference to the role.
