A method of sequentially sorting pieces of material in real-time into output bins where each piece has a composition defined by a plurality of control elements. Each piece is analyzed to determine the concentrations of each control element in the piece. The output bins are assigned target concentrations of the control elements that are defined by customer requirements. The method establishes a bin order used during composition checking to place each piece in a selected bin. The selected bin is the highest order bin that can accept a piece while retaining the actual concentration for each control element of the selected bin within the target concentration for each control element of the selected bin. To optimize the value of the input material to be sorted the bin order is established for each piece based on real-time sort parameters that can determine via global optimization of data from similar input material. Global optimization gives best blends of the known unique compositions and weights of the similar input material to maximize the aggregate value of the prescribed output compositions.
