AHP_FCE-based high-rise building construction risk assessment

Abstract

Abstract There are many uncertain factors in the construction of high-rise buildings. By identifying the risk factors existing in the construction of high-rise buildings, this paper establishes a comprehensive evaluation index system for construction risks of high-rise buildings; and the method of combining analytic hierarchy process and fuzzy comprehensive evaluation is adopted, and the respective advantages are used to establish a construction risk evaluation model; The analytic hierarchy process was used to calculate the weights of the indicators at all levels with the help of MALAB software. The fuzzy comprehensive evaluation method was used to construct the risk evaluation matrix, and the Zadeh operator was used to calculate the evaluation indicators at various levels. The risk factors in the construction process of high-rise buildings are evaluated at the second level and passed. An example verifies the practicability of the above method.
