Positive Solutions of Fully Fuzzy Linear Systems

System of linear equations is a problem that may be solved for solving many problems in various areas of applied sciences. Fuzzy methodsconstitute an important mathematical and computationaltool for modeling real-world systems with uncertainties of parameters. The paper discusses fully fuzzy linearsystems (shown as FFLS ) using embedding approach to find its positive fuzzy number solutions. We investigate an n n (FFLS) and replace the original n n (FFLS) by a 2n2n parametric linear system and finally, numerical examples are used to illustrate this approach.
