This paper develops the definition of parametric form for the optimal ordered weighted averaging (OWA) weights in terms of the convex combination of the basic feasible solutions (BFSs). The paper also proposes the parametric optimal OWA weights of the improved minimax disparity model for any level of orness and n without need to solve this model with many variables and constraints. The usefulness of the proposed method and comparison with the previous results are indicated by using a numerical example.
