The nonfuzzy multiobjective nonlinear programming problem was solved by weighting method approach where the weighting set is obtained by using compromise solution, which was found the minimum and maximum of each objective functionenFuzzy numberMultiobjective nnonlinear programmingTrapezoidal fuzzy intervalTrapezoidal fuzzy numberUR-Proceedings
