Environmental risk evaluation of overseas mining investment based on game theory and an extension matter element model

Abstract Taking into account the limitations of the single weighting method presently used for the environmental risk evaluation of overseas mining investment, an improved extension evaluation method based on game theory was developed. The method was then applied to real data from the Philippines an...
