inputting the cleanup evaluator output and the emissions engine output into an aggregator to achieve an aggregated solution;
optimizing the aggregated solution to achieve optimized results;
performing the method repetitively for all times related to a choke schedule; and
performing a cleanup operation in the wellbore with the optimized aggregated solution corresponding to each time of the choke schedule of the method.
