A system configuration and techniques for optimizing schedules and associated use predictions of a multiple resource planning workflow are disclosed herein, applicable to environments such as radiologist scheduling in a teleradiology workflow. In one embodiment, a series of computing engines and components are provided to allow detailed forecasting and the generation of customized recommendations for scheduling and other resource usage scenarios. This forecasting can factor resource efficiencies, changes in resource demand volume, resource specialties, resource usage preferences, expected future events such as the removal or addition of resources at future times, and other resource availability or usage changes. The forecasts may be further enhanced through the use of historical data models and estimated future data models. Additionally, a calendar and other tools may be presented through a user interface to allow forecast and scenario customization based on selection of a series of future dates.

The method of claim 1, wherein the prediction of any shortfall or excess in radiologist staffing levels is presented to a user as a range of values with an accompanying confidence level. 14. The method of claim 1, further comprising comparing expected radiologist availability and expected radiology read request volume to actual data after occurrence of the future time period. 15. A method for radiology read demand planning and forecasting, comprising: obtaining, at a computer system, baseline data for a future time period by selecting historical data of radiology read activities occurring during a prior time period, the prior time period having common characteristics to the future time period, and the historical data being obtained from radiology read activities performed for a set of past medical facilities having common characteristics to a set of future medical facilities projected for the future time period;predicting, with the computer system, radiology staffing and demand changes to the baseline data expected to occur by the future time period, the demand changes being predicted for the future set of medical facilities;integrating, with the computer system, the baseline data for the future time period and the expected radiology staffing and demand changes to the baseline data in a data model for the future time period; andto forecasting, with the computer system, expected radiology read demand for the future time period at the future set of medical facilities with results from the data model, to predict any shortfall or excess in radiologist staffing levels based on a plurality of constraints related to matching selected radiologists to demand from selected medical facilities, the constraints including one or more of radiologist specialties, radiology procedure types, radiologist credentialing, radiologist licensing, radiologist scheduling, radiologist availability, radiologist efficiencies, radiologist preferences and restrictions, medical facility preferences and restrictions, and medical facility location. 16. The method of claim 15, wherein forecasting the expected radiology read demand occurs through a regression on the data inputs and modeling projected orders for subsets of time within the future time period. 17.
