Standard form of interval linear programming and its optimal objective (interval value)

A standard form of interval linear programming was defined. The solution of the best optimal objective value and the worst optimal objective value of the standard form was studied. Interval objective function, interval inequality constraints and interval equality constraints were discussed separately. By this way, exact linear programming to find the best and the worst optimal objective value of IvLP can be built. Finally an example was given and some complementary comments were made.
