Study On Collection And Balance Mechanism Of Railway Freight Station Under Pallet Sharing

As an important part of modern logistics service,railway freight transportation accounts for less than 10% of the total freight transportation in recent years.The direct reason lies in its poor timeliness.Therefore,the operation efficiency of the railway freight station needs to be improved urgently.For example,loading/unloading of a single full truck requires six forklifts to work continuously for six hours,which results in the long-term restriction of the turnover capacity of terminal freight station on the use of railway freight capacity.In recent years,the "shared economy" has given birth to the social pallet rental,which has brought new opportunities for reducing the cost and increasing the efficiency of railway freight transport.Therefore,from the point of view of the self-built pallet pool system,this paper studies the collection and distribution balance mechanism of freight station under the pallet pool system.The core content of this paper is divided into three parts.(1)Designing the business process of railway pallet pool system.From the point of view of the self-built pallet pool system,this paper introduces the operation mode of the system,and designs the roles and tasks of the participants in the system,such as general railway,railway bureau,freight station,logistics enterprises and customers.Combining with the existing railway transportation business processes,this paper designs the business processes of the self-built pallet transportation system,including the external process of freight station,the internal process of freight station,the demand dispatching process,the recovery dispatching process and the cost settlement process.(2)Constructing an external demand balance mechanism of freight station under railway pallet pool.Warehousing operation of freight station is the core of the internal business of freight station.From the point of view of warehousing operation balance of freight station under railway pallet pool system,the warehousing business processes before and after pallet sharing are compared and analyzed.This paper establishes the warehousing business process model of railway freight station under the condition of pallet sharing,and carries out simulation experiments on the loading and unloading efficiency of single carriage and the utilization ratio of forklift truck.Then the forklift truck allocation strategy corresponding to the delivery volume is given.At the same time,the balance mechanism of the internal business of the freight station is given.(3)Constructing the external demand balance mechanism of freight station under railway pallet pool.Firstly,the problem of backlog or insufficiency of pallets caused by uneven arrival and departure of freight stations is analyzed.Then,the scheduling demand model of common pallets in railway freight stations is established by using system dynamics.The simulation results show that the empty pallet allocation corresponding to the arrival and departure of goods is obtained.Finally,the paper analyses the impact of common pallets on the demand balance of several freight stations,gives the balance mechanism of external demand of several freight stations,and puts forward some strategic suggestions on cost reduction and efficiency enhancement of freight stations.
