Study On Transportation Planning Based On Logistics

This paper studies the influence of logistics on transportation planning from the point of the social economy system, including demand forecasting, system planning, supporting facilities and overall evaluation downright, roundly and finely, and putting into practice. The status and action of transportation planning on logistics is affirmed through comparing logistics condition with traditional transportation condition, including transportation mode, system planning, network planning and so on.Using systems analysis and model formation, the influence of logistics on transportation demand and system planning is analyzed and studied; calculation method and common forecasting models are also provided, combining with its specialty. What's more, considering the influence of limited factors, the compositive limited mode is provided. The layout planning of distribution centers of hinge type are put emphasis on, which are main transportation fundamental facilities on logistics condition and playing a special role in it. As the syntheses of transportation junction and distribution center, the scale of distribution centers of hinge type have close relationship to the city. The planning methods are the Weightiness Method and Dynamic Clustering Method.Weightiness Method is, ordering the crunodes through comparing the weightiness of the crunodes. The main idea of Dynamic Clustering Method is as follow: firstly, regard all the crunodes of planning region as clustering analytic swatches; Secondly, classify different kinds of crunodes according to certain criterion, which must have typical traits; Finally, sort the crunodes by type. On this basis, the transportation network on logistics condition is planned and Traffic Capability Lower Limit Model is provided. The cost of logistics system is limited and transportation factors are tied in so as to rationalize the transportation process.The influence of logistics on the planning of transportation supporting facilities is provided simply, the influence is discussed among the Electronic Commence, logistics and transportation system either. Through the overall evaluation method, the planning scheme is ensured feasible and reliable.On the one hand, the influence of logistics on transportation planning is made definite; On the other hand, the theoretic and practical methods of development planning of transportation facilities on logistics condition are provided.
