1. A Multi-Receiver Manager (MRM) system comprising: a control processing unit comprising a processor and addressable memory, the control processing unit configured to: predict at least one variable from at least one receiver model; predict at least one variable from a plant model, wherein the at least one variable from the plant model comprises a main steam header pressure; predict a steam outlet pressure at the at least one receiver model by recursively calculating the steam pressure at various points within a piping network of the MRM system using the predicted main steam header pressure; and determine at least one target by an optimizer, wherein the determined at least one optimizer target is based on the predicted at least one variable from the at least one receiver model and the predicted at least one variable from the plant model.
