Integrating enterprise input-output modelling with GIS technology for supply chain analysis

摘要: In the paper an enterprise input-output model of a local supply chain is developed and supported by GIS technology. The supply chain is considered as a network of production processes, which transform inputs into outputs and are located in a given area. GIS technology relates geographical information with the supply chain production and pollution. In particular, all inputs and outputs are geographically referenced in the model.
