Abstract: Based on the existing theories of soft sets, Vague sets and Vague soft sets, referencing on measurement methods of Vague entropy, the paper improves the axiomatic definition of entropy of Vague soft sets by adding a new rule that original axiomatic definition is not involved in meantime. Compared with the previous one, a new entropy measurement method of Vague soft sets is presented, and its application into decision-making is given also, which demonstrates good performance of the new entropy of Vague soft sets.

Key words: Vague soft sets, fuzzy entropy, Vague sets, soft sets
