Risk assessment in open cast mining — An application of Yager’s methodology for ordinal multiobjective decisions based on fuzzy sets

Abstract

This paper discusses the potential application of Fuzzy set theory in the area of risk assessment using linguistic variables/values. The application has been illustrated through its use in an open cast Iron Ore-Mine. Yager’s methodology for Ordinal multiobjective decisions based on fuzzy sets has been chosen since the model only demands ordinal information of experts’ preferences and the importance of each individual factor. Moreover this model can be used by the practising Engineers who may not be having in-depth knowledge on fuzzy mathematics. Typical hazards associated with open cast mining have been used in this application.
