Entropy method refers to a mathematical method used to judge the dispersion degree of indicators. The greater the dispersion, the greater the influence of this index on comprehensive evaluation. Entropy can be used to judge the degree of dispersion of an index.

Entropy method refers to the information management method of "entropy" applied in system theory. The greater the entropy, the more chaotic the system is and the less information it carries. The smaller the entropy, the more orderly the system is and the more information it carries. Entropy can be used to judge the degree of dispersion of an index.

Entropy is a unit of measurement of a certain amount of heat energy that cannot do work in a closed thermal system. Entropy method is a method to determine the weight according to the reliability of information reflected by indicators. Entropy is the unit of measurement of thermal energy.
