1. A computer-implemented method for evaluating at least one prediction and decision method set comprising a prediction method and a decision making method for staged resource planning and modeling of a system, the method comprising: generating a first predicted value set comprising at least one state variable by applying the prediction method of said at least one prediction and decision method set to an initial state of the system for a first stage having a prescribed duration whereby the first predicted value set represents a predicted availability of at least one system resource and a predicted demand of at least one system resource for the first stage; applying the decision making method of said at least one prediction and decision method set to the first predicted value set to generate a first imperfect decision as to how said at least one system resource should be utilized; observing a first actual value set of the system through the first stage which represents an actual availability of said at least one system resource and an actual demand for said at least one system resource for the first stage; determining according to the first actual value set a first perfect decision corresponding to a utilization of said at least one system resource which optimises benefit; determining a first perfect benefit by the application of the first perfect decision to the first actual value set; determining a first predicted benefit by application of the first imperfect decision of said at least one prediction and method set to said first actual value-set; generating a first rating set for said at least one prediction and decision method set by comparing the first predicted benefit of said at least one prediction and decision method set to the first perfect benefit.
