Abstract

In environmental management, the multiplicity of human value-judgment urges us to develop new types of techniques helping decision maker(s) to make the best decisions. Thus, interdisciplinary methodologies, including sociology, economics, medicine, psychology and engineering, seem to be indispensable for the resolution of current problems in environmental management. This paper reviews some kinds of methodologies for decision support in environmental management, which cover optimization models for assessment of environmental and resource policies, multi-attribute utility functions evaluating the preference of the decision maker(s), graph-matrix methods handling the complexity of the environmental problematique, interactive solution techniques for multi-criterion optimization, group decision by the extended contributive rule method, fault-tree analyses for environmental risk assessment, and so forth. Both the merits and defects of each method are made clear throughout the argument.
