System 2000 data base for MAGEN data and its associated Fortran programs

Abstract
The methodology for performing a systems-analysis study of energy research and development strategies consists of solving time-phased linear-programing problems that describe the energy supply-and-demand system of each participating member country or organization. The specific aim is to determine what energy-related technologies most warrant development. Model development is occurring at Brookhaven National Laboratory and at Kernforschungsanlage (KFA) in Juelich, West Germany. This report describes the data-handling system at Brookhaven. It is designed and developed so that data can be easily exchanged between BNL and KFA. Indeed, the system is designed to handle data for any linear-programing model written in the PDS/MAGEN language. The data-handling system centers around an automated, System 2000 data base. This entity stores the data and allows for simple procedures to change them either interactively or in batch mode. Associated with the data base are standard formats for inserting and eliciting the data and interface Fortran programs to facilitate insertion and extraction. These programs are written very efficiently in the sense that modular subroutines can be used in several different programs without change. 9 figures. (RWR)
