Abstract:
This article discusses the solution of multi-objective linear programming of trapezoidal
fuzzy numbers using the weighting method. The coefficient of the amount
material production and the coefficient of the amount material available are in the
form of fuzzy numbers because of uncertainty. The solution of this problem is to
convert the trapezoidal fuzzy numbers on the coefficient of the constraint function to
a crisp number using a ranking function, then converting the multi-objective function
into a single objective function are used the weighting method and solved by
the simplex method. It can be concluded that the weighting method can be used as
an alternative method in solving multi-objective linear programming problems.
