Abstract: This paper proposes two new models for OWA weight determinination based on the minimized disparity of two adjacent weights.The nonlinear optimization problem is solved to obtain the OWA operator weights under a given orness level.Finally,the paper presents a numerical illustration to compare the two models with other models and demonstrate their feasibility.

Key words: OWA operator, operator weights, orness, model
