1. A computer-implemented system for performing accuracy analysis with respect to forecasting models, wherein the forecasting models provide predictions based upon a pool of production data, comprising: a forecast accuracy monitoring system for monitoring the accuracy of the forecasting models over time based upon the pool of production data; a forecast model construction system for building and rebuilding the forecasting models based upon the pool of production data; wherein the forecast accuracy monitoring system and the forecast model construction system are configured to operate concurrently; wherein the forecast accuracy monitoring system is configured to provide an indication in response to forecast accuracy of one or more of the forecasting models not satisfying pre-specified forecast accuracy criteria; wherein the forecast model construction system is configured to rebuild one or more of the forecast models in response to the provided indication.
