In this paper, a biref survey of multi-objective optimization techniques for environmental assessement in the region is presented. First, properties of regional environmental systems are exmained, and evaluation criteria for methodologies, which shall be applied to the environmental systems analysis, are presented. After reviewing a short history of methodologies, which have been utilized in water resources systems, a special stress is placed on utility approaches to evaluation of the environmental systems. Among them, the SWT method and the MUF method are discussed. For making up for some shortages of both methods, an alternative method -the NLM method- is proposed, and distinct characteristics of this method are examined. Examples of empirical studies using these methods in Japan are referred. In short, in determination of preferred solutions, the role of the decision maker is regarded as important even though the Arrows Possibility Theorem has been well-known.
