Abstract

In certain embodiments, a control/optimization system includes an instantiated model object stored in memory on a model server. The model object includes a model of a plant or process being controlled. The model object comprises an interface that precludes the transmission of proprietary information via the interface. The control/optimization system also includes a decision engine software module stored in memory on a decision support server. The decision engine software module is configured to request information from the model object through a communication network via a communication protocol that precludes the transmission of proprietary information, and to receive the requested information from the model object through the communication network via the communication protocol.

First claim

The invention claimed is:

1. A computer-implemented method, comprising:
instantiating a plurality of model objects on a plurality of model servers, wherein each of the plurality of model objects comprises a model configured to model operation of a plant or process being controlled, and wherein at least one of the models contains protected information;
requesting information from the plurality of model objects via a communication network;
receiving the information from the plu…
