In the real-world, most information systems are based on dominance relations and may be inconsistent. Moreover,taking the imprecise evaluations in the description of objects into account, intuition fuzzy information systems are introducedto handle with this problem. In this paper, attribute reductions are discussed in inconsistent ordered intuitionfuzzy information decision tables. The concept of assignment reductions is proposed which meet different requirements ofthe existed reductions. Practical approach to compute this kind of reductions is presented by introducing of discernablematrix and discernable function. Moreover, a toy example is employed to illustrate the feasibility of the approach.
