UPED79 Report on revisions of the Utah process economic and demographic impact model (UPED)

This report describes the Utah Process Economic and Demographic Impact Simulation Model (UPED) and the computer soft ware that implements it as they have been developed and refined as of February, 1980. The acronym UPED79 refers explicitly to the refinements to the model and its software which were achieved in a project funded by the Office of the State Planning coordinator and carried out by the authors of this report during 1979. The general concept of the model remains basically unchanged from its initial design as established in 1970. The many refinements implemented since then are discussed in this report. The software package has been completely revised from earlier versions. The software described in this Report is all new with the UPED79 version of the model.
