Evidence theory in the construction of linguistic variables for minerals industry

Among other types of sustainability indicators, linguistic variables have been proposed. During the past few years considerable effort for using the fuzzy logic and linguistic variables (LVs) in environmental decision-making for the mineral industry has been made. The linguistic variables defined could, among others properties, describe the property of acceptability for environment for various environmental indicators. Some proposals for construction of such variables are based on administrative decisions from environmental impact assessment procedures for mining, which provide information for acceptability of quality kind for environment (e.g. obtained from public participation, experts, environmental administration). The measures of evidence for construction have to be based on sets (not only on the members of sets). The administrative decisions with their statements and explanations could be considered as such sets. The measures of evidence appropriate are plausibility and belief measures. Using the more elaborated methods from the theory of evidence, the better estimation of those measures could be achieved. The methods of constructing the linguistic variables, previously suggested and based on obtained measures, are also discussed.
