Solving Multiobjective Linear Programming Problem Using Interval Arithmetic

Abstract In the real world, we often encounter cases where the information / data items can’t be determined with certainty. Hence the value of the datum in the data is assessed using an interval. Meanwhile multiobjective linear programming model is more adequate to describe the problem in the real world. Thus, the multiobjective linear programming problem will be developed into a multiobjective interval linear programming to estimate these uncertainties. Interval programming is one of the tools to tackle uncertainty in mathematical programming models. In this paper, it will be presented the multiobjective linear programming problems with interval numbers as coefficients and values of its variables are also in the form of intervals. The problems will be solved by modified simplex method.
