Integrating Enterprise Input-Output Modelling with GIS Technology for Supply-Chain Analysis

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. Finally, a case study related to the local supply chain of an Italian multinational company producing leather upholstery is considered and different spatial organizations of production processes are analysed, based on the reengineering project of its production processes. In particular, it is discussed how the co-localization of similar production processes can affect the supply chain productivity and environment.
