An Approach of Internal and Fuzzy System of Linear Equations

The system of linear equation has a great importance in many real life problem such as economics, optimization and in various engineering field. The system of linear equation, in general is solved for crisp unknowns. For the sake of simplicity or for fuzzy computation it is taken as crisp value. In actual case the parameters of the system of linear equations are modeled by taking the experimental or observation data. So the parameters of the system actually contain uncertainty rather than the crisp one. The uncertainties may be considered in term of interval or fuzzy number. Recently different authors have investigated these problems by various methods. These methods are described for system having various type of fuzzy and non fuzzy parameters. Although solution are obtained by these methods are good but sometimes the method requires lengthly Procedure and computationally not efficient.
