Environmental Impact assessment for construction material extraction involves many uncertainties, complicated alternatives, and varied preferences, which make it hard for a decision maker to choose what to do in order to provide or meet on-going supply and future needs to its industry (consumers) whle having minimal environmental effects. In this study, a decision support framework and a computer software package were developed to improve environmental optimisation and resource management for extractive industry. The framework uses a combination of scenario analysis, system optimisation, simulation, and decision analysis in a user-friendly decision support environment. The model, a hierarchical additive weighted value-function, was used as a part of a decision-makmg process to select the best alternative. A case study on Quarry Development (Brew Road, Tynong North) has shown that this approach can be used in obtaining better decisions balancing environmental and developmental needs and demands on behalf of the community
