We evaluated the quality of management of infectious diseases in hospitals with analytical hierarchy process (AHP). An attempt to work out assessing model for the management of infectious diseases by establishing a Goal Tree and groups of indices is presented. The rankings, indices and stresses in each assess of this model were established by the request of the content and quality of management of infectious diseases. The Consistent Index (C.I) was used to test whether the contrast rankings of the model were logical, making the logical judgement of evaluated factors quantitated. The results show that the model is scientific and feasible.
