1. A method for adjusting a blend composition, comprising:
receiving, with at least one processor, target blend composition data associated with a target blend composition associated with a first order having at least one target blend property, wherein the target blend composition comprises a plurality of blend components, and the target blend composition data comprises a target concentration associated with each of the plurality of blend components;
controlling, with at least one processor, a plurality of blend component flow streams to cause the plurality of blend components to be added to a blend tank to form a blend composition;
determining, with at least one processor, at least one property of the blend composition;
comparing, with at least one processor, the at least one property of the blend composition with the at least one target blend property;
determining an updated target blend composition having at least one updated target blend property;
generating, with at least one processor, control flow instructions based on the at least one property of the blend composition and the at least one updated target blend property; and
adjusting, with at least one processor, at least one blend component flow stream of the plurality of blend component flow streams to form the updated target blend composition in the blend tank;
wherein the updated target blend composition is associated with a second order different from the first order.
