The cognitive map technique, a heuristic computer aided method for structural modelling based on graph theory, is employed to build systematically up a structural model of social and/or economic system. In this study, an algorithm to prepare cognitive maps containing loops is proposed. Whether the prepared cognitive map is propriety is judged by using the conditions of (1) There should not be any illogical imbalances in the map and (2) The system model described by the cognitive map is to be stable to some extent. For the second condition, analysis on system dynamics is carried out using the concept of pulse process which is formulated with state equation of discrete-time system. Another simulation study using KSIM is also carried out on the vital concepts extracted from the revised cognitive map. The proposed method is applied to the preparation of the cognitive map for maritime industry, which is composed of shipping, shipbuilding, and port & harbour, under recession in the developed countries. The structural issues involved in the maritime industry are examined, and the influence of innovation of the related production technology is simulated.
