A linguistic evaluation approach for strengthened safeguards relevant information

This paper focus on the synthesis and evaluation analysis of nuclear safeguard relevant information based on the linguistic assessment. After a hierarchical analysis of States nuclear activities on the basis of the IAEA Physical Model, the objective addressed is divided into several less complex levels. Then we focus on the aggregation process in every level with consideration of the different kinds of qualitative criteria, like the strength degree of indicator, reliability of information, while we consider symbolic approach acts by the direct computation on labels instead of the approximation approaching using the associated membership function. In this context several kinds of presented aggregation operators within symbolic approach are analyzed. The overall evaluation of objective can be obtained step by step from aggregation of several lower levels. A case-study on application of these aggregation operators to the fusion of safeguards relevant information is provided.
