Application of Pareto frontier in searching for compromise rules of Baikal lake level control

Computer decision support technique for the search for compromise rules of Baikal Lake level control and of Angara River water resovoir cascade control is described. The proposed technique takes into account presence of contradictory requirements that give rise to the vector of decision criteria. The technique is based on dialogue Pareto frontier visualization. It supports the experts in the process of searching for efficient tradeoff among requirements and helps to justify their choice. By using the technique, a compromise cascade control rule was constructed that corresponds to all principle requirements and is used now as a basis of governmental documents concerning water resources control of the Angara River basin.
