In this paper we propose a simple non-parametric model for multiple crite-ria supplier selection problem. The proposed model does not generate a zeroweight for a certain criterion and ranks the suppliers without solving the modeln times (one linear programming (LP) for each supplier) and therefore allowsthe manager to get faster results. The methodology is illustrated using anexample.

Abstract We present a novel approach for approximating the primal and dual parameter-dependent solution functions of parametric optimization problems. start with an equation reformulation first-order necessary optimality conditions. Then, we replace solutions some find test parameters optimal coefficients as single nonlinear least-squares problem. Under mild assumptions it can be shown that sta...
