Research On Transshipment Of Sharing Bike Inventory Control

With the emergence of sharing bicycles,although it is convenient for users to travel,there are also many problems.For example,sharing bicycles appear in blind roads,and vehicles cannot be repaired in time and free parking.With the stability of the sharing bicycle market,companies have begun to focus on issues such as "no sharing bicycles can be borrowed" and "random parking".Focusing on solve the problem of "go to travel or go home in last mile".Therefore,under the premise of ensuring the user's experience,it is very important to study a reasonable sharing bicycle Inventory levels.The research on sharing bicycles is mainly divided into three different directions,the location selection of sharing bicycles,the supply and demand relationship of the number of sharing bicycles,and the optimization of sharing bicycles scheduling.On the basis of these existing studies,we aim at the existing problems by literature analysis,and find that high-efficiency vehicle transshipment can effectively reduce the operating cost of the enterprise,increase the number of Sharing bikes used,reduce the investment of new bicycles,and make the distribution of Sharing bikes more balanced.Firstly,this article introduces the current status of the development of sharing bicycles.On the basis of urban public bicycle research,the problem of vehicle transfer for sharing bicycles can be regarded as a traditional inventory management problem by analyzing the literature of scholars,and define the location of sharing bicycles in the urban transportation system is determined.Based on the research of the mature bicycle sharing system abroad,combined with the inventory control problems of domestic sharing bicycles,the Markov decision process application and the sharing bicycle inventory problem are combined.Then introduced Markov decision process theory and its application,using the mathematical method of Markov stochastic process to study the inventory control problem of sharing bicycles,and divided the transportation problem of vehicles into two parts,one problem is the management of sharing bike inventory in a single location.The other problem is the management of sharing bike inventory in a networked inventory model with multiple locations.In a single point problem,we study the transport patterns of sharing bicycles in a region or a station,and decide whether to move more sharing bicycles out or bring in sharing bicycles to fill in themissing pieces.In multiple locations,considering the non-aftereffect of Markov decision process and multiple locations inventory levels,combine inventory transfer model,we modelling Inventory cost function mathematical model.In the process,inventory transfer(including active transfer of products and passive transfer to maintain inventory level balance)is used to alleviate the problem of sharing bicycles accumulation and sharing bicycles absence.The research is at a certain stage,we studies the characteristics of the solution set of the inventory cost function when the sharing bicycles is piled up,and combines the proposition with the practical application to provide suggestions for solving the inventory problem of the sharing bicycles.Finally,based on the actual data,an example is constructed to illustrate the importance of efficient transportation of Sharing bicycles.Take the city center street as the research object,we design a new transport scheme with existing bike-sharing docking stations.we can get the demand for borrowing and repaying over time based on data analysis.And determine the requirements for each site for optimal decision.It also provides the basis for the transportation decision of sharing bikes and the scientific site selection.
