Construction safety risk evaluation of property engineering projects on the basis of G1-CRITIC-IT2FS-MARCOS

Abstract

Property engineering project management is faced with increasingly complex risks and challenges. If these risks are not effectively controlled, it is easy to lead to cost overruns, time delays and even project failures. This study proposes a property engineering construction safety risk assessment method based on the IT2FS-MARCOS method to address the uncertainty of risk assessment caused by the subjectivity of expert decision-making and the problem of considering multiple risk factors under different risk parameter weights. A property engineering construction safety risk indicator evaluation system was constructed, and the combination of the G1 weighting method and the objective weighting method (CRITIC) was used to analyze the weights of each risk indicator. Interval type-2 fuzzy sets (IT2FS) were introduced to improve the compromise-based alternative ranking method (MARCOS) in multicriteria decision-making. The utility function values of each risk factor were calculated, and the construction safety risk factors of property engineering projects were analyzed and evaluated based on the utility function values. The findings reveal the dynamic process of construction risks in property engineering projects. The model not only considers the fuzziness of expert evaluation but also adopts a multicriteria decision-making method to avoid simple weighting of risk parameters. This method has a high degree of fit with engineering practice and provides a new approach of handling risk assessment in uncertain information of property engineering.
