Abstract
A hierarchical structure was proposed in multi-objective evaluation (ex. AHP). But, in the real world, there are many cases where it is difficult to make a hierarchical structure, because the decision-maker cannot understand the problem clearly. In theses cases, it is necessary to support making hierarchical structure in order to let the decision-maker recognize objects of the problem's evaluation and relationships between objects. This paper proposes the method of making hierarchical structure of objects using structural modeling.
