Vulnerability of the Building Construction Safety System Based on ANP-SD

Abstract

The study aims to analyze the evolution trend of system vulnerability under the interactive relationship of building construction risk factors. Based on social technology theory, the influencing factors are analyzed from four subsystems: individual, technology, organization management, and internal and external environment. By using the method of “network AHP” (ANP), the “relative value” and “absolute value” of each factor are established. A comprehensive simulation model is established to simulate and analyze the “single” and “combined” control modes. The results show that, compared with the vulnerability of the building construction system in the initial state, the minimum decline of the vulnerability evolution trend of the building construction system is only 1.28%, and the maximum is only 14.2% after adopting a single control measure. Among them, the biggest decline in the vulnerability evolution trend is the construction of enhanced safety culture in personal subsystem control measures. After taking joint control measures, the decline of vulnerability evolution trend of the housing construction system is [25.96%, 36.8%]. The control effect of joint control measures is not that the more control measures are taken, the better. However, it depends on the absolute coefficient of the related factors of the influencing factors of the trunk center and the subsystem to which they belong to provide a reference for the risk control of housing construction.
