Abstract
In this work, it is shown that when fuzzy measure set which has cone structure is closed, generating and norm normal, it obtains Riesz decomposition. Thus, it is indicated that each fuzzy measure can be stated as the linear combination of non-monotonic fuzzy measures.
Keywords:
Non-monotonic fuzzy measure, Banach space, Riesz decomposition

1. Introduction
Murofushi [1] had introduced the fuzzy measurement concept that is not monotone by removing monotonousness characteristics defined on fuzzy measurements and examined the features that belong to a special subset that has bounded variation feature of these measurements in his study. In Jang and Kwon’s [2] study, they had extended Murofushi’s assumptions with the help of the
based on bounded variation that Schramn [3] had presented. Narukawa [4] had examined the features of convergence in Banach space that non-monotonic bounded variation structured measurements had generated. In this study, features of the cone structure created by the fuzzy measurements that had bounded variation feature had been examined and it had been indicated that it had the Riesz decomposition characteristic. Thus, it had been showed that every fuzzy measurement could be expressed as the combination of the non-monotonic characteristics.

Definition 2.2: If

has composed a relation and hereby chain structure has appeared as the combination of the sequential elements. Definition 2.3: Total variation value

When data features had been provided for the given two theorems Banach space and
cone embedded into it in the rest of study, related space has showed that it satisfies the Riesz decomposition characteristic. Theorem 2.3 [7] Let be Banach space and

Theorem 2.4 [8] If is ordered Banach space and
cone which is defined in this space is closed, generating, norm normal structured cone, it has the following characteristics. Banach space has the Riesz decomposition characteristic. The dual of Banach space is Riesz space. The dual of Banach space has the Riesz decomposition characteristic.It had been showed that
ordered Banach space and
cone that belongs to this space have closed, generating and norm normal characteristics. With the help of the Theorem 2.3, it is clear that
Banach space has Riesz decomposition characteristic so
cone has it. This case has indicated that every
fuzzy measurement can be expressed with the help of non-monotonic fuzzy measurements.
3. Conclusions
It had been revealed that the cone structure formed by fuzzy measurements which were defined in the ordered Banach space that non-monotonic fuzzy measurements created has the Riesz decomposition characteristic under the closed, generating and norm normal structured feature thus fuzzy measurements can be expressed as the linear combination of the non-monotonic fuzzy measurement.
