Study on Safety Evaluation for Construction Sites Based on Fuzzy-AHP and Grey Correlation Analysis

Abstract:

This paper proposes a hybrid evaluation approach combining fuzzy comprehensive assessment method and AHP that measures the safety performance of construction site. The weight of each index was calculated through AHP model which use in fuzzy comprehensive assessment, and then the safety level of construction sites was determined by multi-layer fuzzy comprehensive assessment technique. In order to find out the main causes of safety level of construction site’ changes, the grey correlation analysis was used to quantify the influence degree of each factor of safety level of construction site. The effectiveness of our methodology was verified with an empirical study by using the data of 3 construction sites we investigated. The results show that this approach can be an effective tool to predict the safety performance of construction projects sites, which is useful to provide a scientific basis for the management and decisions of accident prevention.
