Abstract: Objective To determinate the weights coefficient of the comprehensive evaluation indexes in biosafety management of laboratory animals objectively and scientifically.Method The analytic hierarchy process (AHP) was used to define the weight coefficients in 11 synthetic evaluation indexes.Result The most important weight coefficient (0.2157) were that facility environment and health certificate of laboratory animals the consistent ratio (CR) is 0.0209<0.1.Conclusions The weight coefficients in 11 synthetic evaluation indexes have no logical confusion,indicated that this index system and the weight coefficients of indexes could be applied in biosafety management in different units and laboratories.
