Evaluation of safety management standardization of railway construction projects based on rooted theory and G1-CRITIC-Distance Function Judgment-VIKOR
In order to promote the smooth implementation of the management mode of safety management standardization,and the safety management of railway construction projects towards a high standard and high level,the evaluation of safety management standardization of railway construction projects based on rooted theory and G1-CRITIC-Distance Function Judgment-VIKOR was carried out.First,by taking standardized management as the theoretical basis,the data were encoded according to the qualitative research method-rooted theory to establish the evaluation index system of safety management standardization of railway construction projects.It consisted of six core categories and 32 main categories:standardization of system management,standardization of personnel allocation,standardization of material management,standardization of environmental management,standardization of field work and standardization of process control.Second,with the help of the Gini coefficient of the Lorenz curve,the CRITIC method was improved.The"G1-CRITIC-distance function discriminant method"model was proposed to calculate the weight of the attributes.Finally,the VIKOR algorithm was used to conduct empirical analysis on the case projects.The standardized management level was evaluated based on the standardization of security management value UR.The results showed that the level of safety management standardization in each case project presents different states,and UR value is significantly different.The UR value of each item in P1～P5 is 0.047 6,0.148 3,0.451 9,0.971 5 and 0.648,respectively(among which P4 belongs to the"high level";P3 and P5 are"medium-level";P1 and P2 are"low levels").Through the sensitivity analysis under the compromise coefficient disturbance,both the group utility and individual compromise were considered comprehensively.The construction projects of different levels(P1～P5)were discussed separately and decision-making suggestions for standardization construction were put forward.The research results are consistent with the standardization degree of actual safety management in each case project,providing a reference basis for further promoting the standardized management of railway construction projects,the operation of various safety management behavior norms and continuous improvement of management systems for construction projects.
