Claim 14:
15. The method of claim 1, wherein one or more of:
(i) predicting the one or more hydrocarbon feedstock sample properties comprises mathematically manipulating a feedstock spectra signal indicative of the hydrocarbon feedstock sample spectra, thereby to provide a manipulated feedstock signal and communicating the manipulated feedstock signal to an analytical property model configured to predict, based at least in part on the manipulated feedstock signal, the one or more hydrocarbon feedstock sample properties,
(ii) predicting the one or more unit material sample properties comprises mathematically manipulating a unit material spectra signal indicative of the unit material sample spectra to provide a manipulated unit material signal and communicating the manipulated unit material signal to an analytical property model configured to predict, based at least in part on the manipulated unit material signal, the one or more unit material sample properties,
(iii) wherein the controlling comprises generating, based at least in part on one or more of the one or more hydrocarbon feedstock sample properties or the one or more unit material sample properties, one or more processing unit control signals configured to control on-line one or more processing parameters related to operation of one or more of the one more first processing units or one or more of the second processing units,
(iv) wherein the one or more unit sample properties comprise reaction effluent yield, and the controlling comprises controlling one or more of:
riser outlet temperature based at least in part on the reaction effluent yield, or
riser lift velocity based at least in part on the reaction effluent yield,

(v) wherein the one or more unit material sample properties comprises FCC product yield, and the controlling comprises controlling riser lift steam rate based at least in part on the FCC product yield;
(vi) wherein the one or more unit material sample properties comprises riser stripper effluent, and the controlling comprises controlling FCC catalyst stripping based at least in part on the riser stripper effluent;
(vii) wherein the one or more unit material sample properties comprises one or more reaction effluent properties, and the method further comprising on-line modeling, based at least in part on the one or more reaction effluent properties, of operation of the one or more first processing units, or
(viii) wherein the controlling comprises real-time controlling for optimization of operation of the FCC processing assembly.
