Linking the Macroeconomic and Systems Engineering Approaches %U https://pure.iiasa.ac.at/id/eprint/4856/ %V 21 %X Informal linking or softlinking of macroeconomic and systems engineering models can provide a large variety of tools for joint energy-economy analysis. A necessary condition for internal control of such linking is a common, formalized language describing areas of overlap between the models. The principle of common language is discussed and demonstrated for the softlinking of a macroeconomic model (ETA-MACRO) and a systems engineering model (MESSAGE III).
