Abstract

This paper describes a method for assessing risk of the workers at construction sites using interval type-2 fuzzy analytic hierarchy process. Historical accident data, subjective judgments by the experts and relative importance of the risk factors are combined together to determine the current risk level of construction sites. The linguistic terms associated with the model are represented by interval type-2 trapezoidal fuzzy numbers. The proposed method can identify the risk factors which are most important in improving worker safety and, therefore, determines the areas on which the management should emphasize in order to improve the safety of the workers. The application potentiality of this model has been demonstrated by a case example of risk analysis of a construction industry.
