  This paper considers the grey linear programming and introduces a new
satisfaction degree of optimal value for the positioned linear programming of
the grey problem. The {\lambda}-satisfaction degree seems to reflect the real
meaning of the positioned optimal values. By selecting {\lambda} according to
the attitude of decision maker towards the satisfaction degree, an appropriate
optimal solution can be obtained for the grey linear programming problem. An
example is given to show the meaning of the new satisfaction degree.
