Research On The Priority Order Of Construction Safety Improvement Of Rural Construction Engineering Based On Grey Cluster Analysis

The construction industry has long been one of the pillar industries of my country’s economy.With the continuous advancement of socialist modernization,more and more attention has been paid to rural construction,and the contradiction between the demand for rural construction projects and the construction level of rural construction projects has become more and more prominent.And the related research is not substantial enough.This article takes rural construction engineering as the main research object,and starts from the construction management department at the city(county)level.In the case of limited resources such as time and cost,it studies the priority of construction safety improvement of rural construction engineering,establishes an evaluation system,and establishes Priority model,and combined with empirical research to point out targeted improvement measures.This article first analyzes the current domestic and foreign related research results,establishes the main frame structure of this article,and analyzes basic concepts such as the research object,and establishes the theoretical basis for the establishment of the indicator system through the analysis and comparison of the four kinds of accident cause theories.Preliminary establishment of an indicator system based on relevant literature and expert opinions.Secondly,through questionnaire surveys,the opinions of experts in related fields on the importance of each index are collected,and with the help of SPSS software,Pearson correlation analysis is used to reduce redundant indexes and establish the final evaluation system.Subsequently,the judgment matrix of each level is obtained through expert investigation,and the analytic hierarchy process is used to determine the index weight;the gray cluster analysis method is used to correct the strong subjectivity problem of the analytic hierarchy process,establish the whitening weight function and calculate the relevant comprehensive rating index,Based on the calculation results,sort the improvement priority of each level index,and establish the final safety improvement priority model.Finally,empirical analysis is used to prove the practical feasibility of the model,and targeted improvement measures are proposed,and the improvement path is innovatively proposed from both on-site and grassroots supervision departments.
