Methodological Procedure for Relative Weighting of Importance Environmental of Project Actions

Abstract

A complementary methodological procedure to the Environmental Impact Assessment (EIA) that defines a hierarchical structure for the project, allows calculate the relative weight of each action and analytically compares different alternatives is presented. 1000 Units of Importance of Project Actions (UIPA) were assigned to the project under study to be distributed among its elements. Multicriteria decision was used to calculate the set of coefficients (pj) that represents the relative weight of each action. With the application of the procedure developed to the EIA of a mining project, the validity of the method developed to justify mathematically the selected alternative was verified.
