Building assembly safety assessment based on the ISM structural model
At present,the safety assessment of the hoisting of modern prefabricated buildings is a complex and important issue.We have developed an evaluation scheme that includes decision experiments,evaluation experiments,and deconstructive structural models,and the study constructed 20 safety influencing factors and evaluated them using Pythagorean fuzzy sets and Analytic Hierarchy Process-Optimal Solution.The results indicate that the centrality of the investment and use of safety measures is as high as 2.49,with the highest importance.The centrality of the safety standard policy environment is the lowest at only 1.12,with the lowest importance.The reason for the safety emergency plan is as high as 0.75,with the highest impact.The reason for the coordination of D3 job types is the lowest,only-1.24,and it is most affected by other factors.After in-depth analysis of relevant cases,it was found that the application results of the proposed method are highly consistent with the actual situation,which fully proves the feasibility of the method in practical application.The research provides effective risk control strategies and decision support for practical engineering.
