Abstract EN
We aim to investigate intuitionistic fuzzy ordered information systems.
The concept of intuitionistic fuzzy ordered information systems is proposed firstly by introducing an intuitionistic fuzzy relation to ordered information systems.
And a ranking approach for all objects is constructed in this system.
In order to simplify knowledge representation, it is necessary to reduce some dispensable attributes in the system.
Theories of rough set are investigated in intuitionistic fuzzy ordered information systems by defining two approximation operators.
Moreover, judgement theorems and methods of attribute reduction are discussed based on discernibility matrix in the systems, and an illustrative example is employed to show its validity.
These results will be helpful for decisionmaking analysis in intuitionistic fuzzy ordered information systems.
