博士 === 國立臺灣海洋大學 === 航運管理學系 === 101 === The convenience of traffic will be the key factor for the development of economic and international trade. Taiwan is surrounding by sea. Shipping policy is crucial to the development of national containership. Due to increased operating costs, the country containership team development is limited during recent years. The problem of flagging out has become a test of our containership team development facing seriously. The main reasons of flagging out will be the shipowners try to reduce operating costs in response to operation of the regional problems, or an attempt to reduce government control. The main motivation for this study is to explore the ship set membership system. By gathering ship domiciled system, to view the current status of the absence of the country containership industry development and explore the factors of flagging-out. We try to develop a specific response strategies for the relevant government units ship domiciled system specification develop the shipping development policy reference. DEMATEL (Decision Making Trial and Evaluation Laboratory) has been applied in many situations, such as marketing strategies, control systems, safety problems, developing the competencies of global managers and group decision making. It has been incorporated into other methods such as ANP (Analytical Network Process), MCDM (Multiple Criteria Decision Making), fuzzy set theory, etc., to vitalize these traditional methods and explore new applications for the hybrid methods. DEMATEL models the influences of components of a system with an initial direct relation matrix. Influences of components can ripple transitively to other components, which is modeled by raising the initial direct relation matrix to powers. The total influence is computed by summing up matrices of all powers based on the assumption that the matrix raising to the power of infinity would converge to zero. The current paper shows that raising the initial relation matrix to the power of infinity may not converge to zero and hence total influence may not converge. The current paper also shows that our revised DEMATEL guarantees that the initial direct-relation matrix to infinite power will converge to zero and the total influence can be obtained accordingly. The newly developed approach is illustrated with numerical examples.
