Contribution of Fuzzy Minimal Cost FlowProblem by Possibility Programming

Using the concept of possibility proposed by zadeh, luhand-jula ([4,8]) and buckley ([1]) have proposed the possibility programming.the formulation of buckley results in nonlinear programming problems.negi [6]re-formulated the approach of buckley by the use of trapezoidalfuzzy numbers and reduced the problem into fuzzy linear programmingproblem. shih and lee ([7]) used the negi approach to solve a minimumcost °ow problem, whit fuzzy costs and the upper and lower bound. inthis paper we shall consider the general form of this problem where allof the parameters and variables are fuzzy and also a model for solvingis proposed.
