The relation among data objects is not strictly symmetric and transitive in data grid environment, so it is rather difficult to compare their relativity. Combining membership with rough set and introducing them into information retrieval, this paper proposes a fuzzy rough set retrieval model.

Air combat is the basic operational means of air force. This paper models the air combat effectiveness assessment problem as a multi-criteria decision making (MCDM) problem and proposes a two-step evaluation model, combining the technique of fuzzy AHP (fuzzy analytic hierarchy process) and TOPSIS (technique for order performance by similarity to idea solution). This study applies the fuzzy AHP method...
