Study On The Key Technique Of Hub City Logistics Planning

In order to adjust the trend of global logistics and social logistics, constructing social logistics platform is regard as a kind of strategic measure to strengthen comprehensive ability by all countries. It is an important part for the region logistics rationalization that planning of the hub city logistics system. In the paper, city logistics system planning theories and techniques are discussed in combing theories and experience, base on city logistics system structure and development regulations are analyzed. The studies of key problems focus on logistics infrastructure layout and logistics park design.City logistics character and bound are analyzed from the point of view of areas. For the sake of solving logistic nodes appellation confusion, the city logistic nodes are classed and distinguished. Three sorts logistics center are defined, and which function, client and distribution specialty are discussed. City logistics system fabric is constructed from the point of social logistics, which is a pyramidal structure including aim lay, market lay, function lay, operation lay and foundation lay.Basing on diamond theoretic about city competitive ability that proposed by Mack baud, the influence factors of city logistic industry are discussed. City logistic system plan frame is founded and four key techniques, which are logistics demand forecasting, logistics infrastructure positioning, large-scale infrastructure designing and logistics information platform designing, are proposed. Integrative logistics plan is expounded for contraposing problems of current plans, and actualizing approach and grads choice are discussed.With logistics industry layout area theory and logistics infrastructure layout position theory, the rules about city logistics system are analyzed and academic layout model are founded. On base of evolvement of port industrial area, three bound polarization theory is put forward, which is form by port transport, compositive logistics and port rear industry.The logistics system collectivity layout is the import content of plan. In third chapter, layout plan flow is analyzed, the orientation method that transportation place + industry place is proposed, LP (logistics park )-LC (logistics center ) structure layout model is founded. LP-LC model is a non-balanceable and non-linear programming, in which goods sorts and capacity limit are considered. LP-LC model has a four levels network, including source nodes, LPs, LCs, demand nodes. Model takes the highway– conveyance as outside import, and takes freight and storage fee as general cost. Considering the competition between LC and LP, LP and LC are optimized in-phase. The solving process includes goods classed, nodes maximum calculated, feasible nodes combined and capacity filtrated. Lastly, the mode is solved by means of heuristic arithmetic that linearized step by step. The last park of the chapter, to discussed layout evaluate, evaluating index system about city logistics layout is constructed.In fourth chapter, the technology of logistics park design is discussed systematically. The design frame of LP is founded, which comprises five modules, information, strategy, orientation, collocation and periphery. the emphases are the calculating method of LP dimension and plane collocation of macroscopical room.Contraposing the limitation of prevenient method for LP size, a systematic method is produced, which operation is formed by three processes, step one, classing park ground tomanufacture and configuration establishment, step two, calculating dimension of manufacture by dimension rate, and calculating dimension of configuration establishment by manufacture ground scale, step last, attaining manufacture dimension by impacting factors. Using for reference of overseas logistics park, numerical value of all work sections dimension rate and manufacture ground scale are proposed.On base of experience about LP layout, four layout modes are put forward, which is function area, plot, concept park and mixed mode. Conforming to characteristic of LP layout, it is established that a kind of constructing disposal method with controlling structure. The method disposes the area in term of not only inner mainstay, but also exterior restriction. So that the analysis is strengthened, that is effects about inner function area and roadway network to exterior establishment and environments. the method course is as follow: Considering logistics relation and non- logistics relation synchronously, admeasuring coefficient to two relations, founding compositive relationship chart of reference points and inner function area, making the chart of function area relative position, getting the final plan by admeasuring function area and adjusting roadway network. Finally the demonstration about Yang Zhou north LP is given to validate the method.City logistics policy suggestion and information platform design are another important contents of logistics plan, which are discussed respectively in chapter five and chapter six. The problems of domestic logistics managed system are analyzed, and logistics policy comes down to four sorts, which are cultivating policy of logistics enterprise and market, developing policy of logistics infrastructure, advancing policy of logistics standardization and information, fostering policy of person with logistics administrant ability. The city logistics information platform fabric is founded, and implementation phase is advised.
