The problem of fuzzy multi-objective optimization on the basis of fuzzy linear programming is considered. Method is a convenient scheme to find a trade-off decision, in making of which the decision maker takes a direct role defining a level of trust.The model of oil refinery planning considered in this article is described by fuzzy linear dependencies. To simplify the structure and solution, in the model different grades of petrol (in this case A-80, A-92 and A-95) were taken as output products. For solution of the optimization problem fuzzy multi-objective linear programming method, based on Fuzzy Sets Theory, was used. The efficiency of this method is illustrated by calculations and practical applications.
