Further the auxiliary principle technique is used to suggest a novel and innovative iterative algorithm for computing the approximate solution. Consequently not only the existence of solutions of the FMVLIP is shown but also the convergence of iterative sequences generated by the algorithm is also proven. The results proved in this paper represent an improvement of previously known results. Copyright 2009 P. Kumam and N. Petrot.

Introduction The concept of fuzzy set theory was introduced by Zadeh 1 . The applications of the fuzzy set theory can be found in many branches of mathematical and engineering sciences including artificial intelligence control engineering management sciences computer science and operations research 2 . On the other hand the concept of variational inequality was introduced by Hartman and Stampacchia 3 in early 1960s. These have been extended and generalized to study a wide class of problems arising in .
