Theory Research On The Sea-rail Combined Container Transport Organization Of The Inland-port-transferring Railway Hub Container Transport System

ABSTRACT:According to the actuality of the railway container transport in China, and the planning of railway long-time development, the dissertation researches the correlative theory and practice of transport organization and operation management of sea-rail combined container transportation in inland-port transferring Railway Hub Container Transport System (RHCTS). The objectives of this dissertation is to put forward the theory of container transportation and method of operation management of RHCTS fulfilling the actuality of railway container transportation, as well as the planning of railway and tendency of comprehensive transport.The dissertation describes the related achievements of theory researches and practical experience about container transport and multi-modal transportation. Then it puts forward the concept of RHCTS basing on the viewpoint of "construct the comprehensive transportation system and develop the multi-modal transportation". The dissertation studies the complex structure and inner relationship of RHCTS. Based on the "hub and spoke" and regional economic theory, the dissertation brings forward the structure characteristics and system features of RHCTS, such as core trait, net trait, space trait, comprehensive trait, integrated net trait, dynamic coordination trait, and so on.Using the fuzzy clustering method, the dissertation classifies the RHCTS into five types, including comprehensive international-container-port type, domestic sea-rail intermodal transport type, domestic land-water combined transport type, frontier-hinterland type and inland-port transferring type. The dissertation studies the concept of every type, and contrasts the differences of them in terms of system structure, container flow trait, and operation characteristics. The conclusion demonstrates that the ways and means of container transportation organization are different because of the differences of RHCTS type.The dissertation selects the inland-port transferring RHCTS as the object of research, and studies deeply on some crucial factors in its sea-rail combined container transportation organization. These problems include the regional factors analysis, the transport net structure study, especially the study of structure and feature of container transport passage, the composition and traits of dispatching container flow.The dissertation studies the primary characteristics and optimization problems of sea-rail combined container transport organization in inland-port transferring RHCTS, and studies deeply on the multi key factors for building optimum model of it. The dissertation puts forward the specials and complexities of sea-rail combined container transport organization, which are different from the common freight transport. These properties include the inner contradiction, cooperation, information sharing,5R properties, as well as the transferring and hinge properties. According to the multi-objectives optimization feature of sea-rail combined container transport organization in this type of RHCTS, the dissertation introduces the container volume and arrival-time demand from container vessels into the problem of determining the sea-rail combined container train (SRCCT) scheme, which are special in the sea-rail combined responding transportation. Then, following the system optimization rule, the dissertation builds the multi-objective optimization models from three layers one by one basing on responding transportation between sea and railway. These three layers are as follow. The first is to determine the attractive power and attractive scope of the inland-port transferring RHCTS. The second is to determine the forms and schemes of the SRCCTs. And the last one is to determine the responding time between SRCCT and container vessel. The dissertation designs a suitable algorithm to solve these models.In the case study, the dissertation adopts attractive model and fuzzy clustering method to define the attractive scope of Zhengzhou RHCTS, as well as the container ports of its sea-rail combined container transportation. On the base of these, the dissertation works out the form and scheme of the sea-rail combined container train between Zhengzhou railway logistics center of the RHCTS to Qingdao, Shanghai, Guangzhou and Lianyungang. The algorithm gets satisfied results.
