The Research Of Port Supply Chain Flexible Entropy Based On The PS-DLD

Port industry and shipping industry is interdependent unified economies, the study of the relationship between port industry and shipping industry in academia has gradually matured. Along with the development of international trade, and changing economy industry structure, more and more of the production and business operation activities and the allocation of resources in the global scope. The port has become port shipping supply chain an important step in, is not only the key nodes of supply chain, also is the international logistics chain technology node, to the international trade and international logistics functions are becoming more and more important. Therefore, port supply chain flexible strategy has become the strategic focus of port in the global competition.In this paper, first of all, learn from foreign shipping port of theoretical research and practice of the development of the industry, from a strategic analysis of evaluation of China’s port shipping development present situation, research and Analysis on the theoretical foundation and port shipping dependency linkage development, port and flexible development concepts and based on the shipping port dependent development of linkage of port supply chain flexible (PS-DLD, Dependence Linkage Development of Port and Ship); Secondly, based on port shipping dependency linkage development mechanism, studying port supply chain flexible mechanism, flexible capabilities, SWOT strategic positioning and development strategy analysis; Then, based on the PS-DLD, port supply chain flexibility evaluation, architecture evaluation index system, puts forward a flexible the concept of entropy, and the analysis of port supply chain flexible gray evaluation model; Finally, select three ports of the central Bohai on the empirical calculation, calculation results are analyzed, and puts forward the related proposal.
