In this paper, a scalar Er-expected value operator is used for solving the fully fuzzified linear programming problem where all the parameters are fuzzy stochastic and variables are continues fuzzy numbers. The presented solution method is based upon Erexpected value of fuzzy random variables, fuzzy optimization method based on multiobjective programming method and fuzzy ranking method. An illustrative numerical example is given to clarify the theory and the method discussed in this paper.
