Attributes for calculating weights include human attributes, clinical attributes, and disease attributes, and the numbers listed in the matrix represent the preferences among the attributes. The higher the value in the matrix is, the higher the value is compared with the relative attribute, and the smaller the value, the smaller the preference.
The attribute information for determining the weight can be largely classified into human attribute, clinical attribute, inspection attribute, and disease attribute. In one embodiment of the present invention, the weight calculation process according to the classification will be described. However, it is to be understood that the attribute information is not limited to the above, and that the weights can be calculated on the basis of the detailed attributes belonging to the human attribute, the clinical attribute, the test attribute, and the disease attribute.
