This invention discloses a method for screening and determining the configuration of a gear measurement center in multiple scenarios, belonging to the field of precision testing technology and instrument design. The method takes candidate configurations of the gear measurement center as the object, and sequentially establishes a configuration error score model, a configuration stiffness score model, and a structural compactness score model. The measurement scenarios are divided into small module, medium module, and large module scenarios according to the gear module.
