In this paper we present an extended version of the XC-model (Xu and Cai in Group Decis Negot 21:863–875, 2012) for group multiple attribute decision making problem. The proposed model is a linear programming model based on deviation function to find the optimal expert weights. An illustrative example is given to compare our results with XC-model.
