A note on article "The evidential reasoning approach for multiple attribute decision analysis using interval belief degrees"

Wang et al. use an evidential reasoning approach for solving multiple attribute decision analysis (MADA) problems under interval belief degrees [Y.M. Wang, J.B. Yang, D.L. Xu, K.S. Chin, The evidential reasoning approach for multiple attribute decision analysis using interval belief degrees, European Journal of Operational Research 175 (2006) 35-66]. In this note it is shown some nonlinear optimization models in that paper are incorrect. The necessary corrections are proposed.
