Abstract: Upto now, there are many kinds and theory on grey linear programming,such as greyforecasting linear programming, grey target programmming, linear programming of grey intercal, andlinear programming with grey numbers [1~l7]. The objective of this paper is to deal with a kind of greydrift linear programming(GLP)through the mediums of procedure that turning GLP into parametriclinear programming via the mathematic programming. Some useful results for the benefit of solving GLPis expounded and proved, discussed and developed.

Key words: Linear programming, Drift linear programming, Decision making
