Abstract
Toward clarifying structural factors in the lack of fishery successors and devising countermeasures to such lack, this paper analyzes the applicability of AHP (Analytic Hierarchy Process). The DEMATEL (DEcision MAking Trial and Evaluation Laboratory) method, based on a pair comparison questionnaire survey, was used to clarify the factors constituting the structureo f the problem. The ISM (Interpretive Structural Modeling) method examined the relationship between the causes and effects of the factors identified by DEMATEL by setting the boundaries of 1 (“yes”) and 0 (“no”) for the data obtained by DEMATEL.,
AHP was then used to weight three evaluation criteria (industrial, cultural, regional maintenance), and then to rank them. The resulting weighting was used to rank the effectiveness of each remedial measure in terms of each of the evaluation criteria.
