In sustainable planning such as transport and river improvement we should consider needs and requirements of the planning site. Here, we propose a method of public involvement for sustainable river improvement planning. The method includes the concept of strategic environmental assessment and evaluating techniques on regional opinions. That is, based on the procedure of building policy, plan and programming, several techniques are combined at each stage. A workshop operates such a decision-making system. Keywords: strategic environmental assessment, workshop, fuzzy structural modeling, conjoint analysis, Choquet integral. 1 Introduction Recently, the new methodological purpose of a river improvement includes sustainable planning that brings affordability of carrying capacity and contributes quality of life. The objective of this study is to introduce sustainable ideas of a river basin improvement, to propose a trial balloon and to examine a practical model for the specified process of planning in view of sustainability. First of all, we propose a dialogue system of decision-making. Here, the opinions and information can be exchanged among three groups for planning concerns, that is, the administration, the community and the adjusting group of them. A workshop is generally available for constructing the interrelationship among such groups. Moreover, we introduce some technical methods such as Fuzzy Structural Modeling, Conjoint Analysis and Fuzzy Evaluation Technique into the workshops dynamically to support decision-making.
