Abstract: | The collection, collation and transformation of data into the form required by a large energy-economic model constitutes a significant part of the overall modelling activity. The correct basis for setting up a model data base rests on the separation of the model specification into the four areas of external data transformation, internal data representation, internal data transformation and the mathematical relationships. From this specification, the model may be generated. The internal data base is comprised of a series of tables, covering intersectoral transactions, capital stock transactions, energy sector operating characteristics, consumption patterns and other data. These tables may be compiled direct from source material, or via some research requiring prior data processing. In both cases the process should be fully documented, so that data accuracy is ensured and the data may be updated reliably when new material becomes available. It is recommended that a data coordinating function be established within the modelling group, in order to plan and control data-related activities. |
