Abstract
According to the increase both in scale and complexity, problem-solvings in today's engineering are being forced to have a close relation to societal systems. This will tend, in turn, to produce conflicts referring to individual sense of value among the groups associated with decision making. To attain at a square and rational goal in such techno-socio-system, therefore, it becomes very important how we will deal with the conflicts.
Concerned with such situation, in this paper, we have proposed a supporting system for group decision making in the paradigm of the systems approach. A procedure has been developed using the analytic hierarchy process (AHP) to reveal value structure and an interactive method of the multi-objective optimization to evaluate and adjust the attainability of each group's goal. Through numerical experiments applied to a rad-waste management system with risk evaluation, we have shown the proposed approach very promising to deal with such problem-solvings concerned here.
