Safety Evaluation of Construction Based on the Improved AHP-Grey Model
- 36 Downloads
The construction industry plays a major role in Chinese economy, but associated with a disproportionately high number of injuries and fatalities. In this paper, we proposed a improved AHP-Grey Model which has 4 limitations before. A safety hierarchical framework was established and attributes were identified through reason analysis method of Accident Chain Reaction Theory and 4M Theory; attributes weights were determined by Interval Analytic Hierarchy Process instead of AHP, and the safety checklist was also improved; grey relative Euclid weighted correlation degrees were calculated for safety level ordering instead of Deng’s grey correlation degree. The improved model can better reflect the actual safety condition of the construction.
