The information system by uncertainty theory

الملخص EN

The theories of uncertainty are very useful to treat with mathematics that needs to address and in providing a flexible model to elaborate uncertainty and vagueness involved in decision making.

In this paper, we used the information system by converting the information system to the triangular fuzzy number matrix; into its membership function and by computing the relation matrices to take the suitable decision with degree.

In this paper, we also introduced an application in real life.
