1. A computer-implemented method, comprising: receiving worksite objectives for concurrently operating a plurality of different worksites; using a computer-implemented model generator to generate a reference model that provides a model output indicative of modeled operation of the plurality of different worksites; and generating control signals to perform closed loop, near real time control of the operation of the plurality of different worksites using the reference model, comprising: receiving operations data through a communication system indicative of an actual worksite performance; comparing the operations data to the reference model and generating an error output using a computer-implemented error calculation component; comparing the error output to a threshold; and generating the control signals based at least in part on the comparison between the error output and the threshold; generating a recommended adjustments output indicative of adjustments to the plurality of different worksites based on the comparison of the error output to the threshold using a computer-implemented decision support system; and generating the control signals based at least in part on the generated recommended adjustments output.
