Study and Applications of Analytic Hierarchy Process

AHP (analytic hierarchy process), as a comprehensive safety evaluation method combining qualitative and quantitative analysis, has been used in many fields of safety and environmental science. The applications of AHP, improved AHP, FAHP (fuzzy AHP), improved FAHP and gray AHP in safety and environmental science were analyzed, summarized and prospected. The major factors affecting the work of occupational hazard supervision were analyzed. Considering the advantages that AHP can decompose the complex issues and provide the scientific basis for the choice of optimal decisions, it was proposed to use AHP in the fields of occupational hazard supervision.
