[Abstract]:The small part express service of road passenger transport is a new way of express transportation service, which uses the passenger line and the spare baggage cabin of the passenger bus to carry small parts. This paper studies the design of the network of the passenger small part express transportation service, and optimizes the allocation of resources. It is of practical significance and research value to improve service level and competitive advantage. Firstly, the spatial and temporal structure of the small part express service network of road passenger transport is analyzed and constructed by using the method of node splitting. Through the detailed analysis of the network resources involved in the small express transport service of road passenger transport, combined with the network resources of the passenger transport line and the operation characteristics of the passenger transport network, On the basis of axis-spoke express service network structure, the service transfer stations and stop stations that accord with the characteristics of passenger transport operation are added, and the axis-spoke network structure of direct service and transshipment service is constructed. Then, the network nodes are split according to the job content involved in the network, and the space-time network of the small-piece express service for road passenger transportation is constructed. Secondly, the corresponding service is designed according to the requirement feature, and the design method of service group is given. On the basis of the network structure, considering the demand of time, capacity and service level of passenger network resources, from the time series of service, the frequency of operation, and so on, Design cost and capacity four aspects of the design of small express service design, and then, according to OD demand distribution and service level requirements, design the corresponding service groups, at the same time, give different levels of small piece network flow service group selection method, By analyzing the characteristics of passenger transport demand and service level, considering the time limit and capacity constraint of passenger transport network, the service groups that meet the requirements of small-piece network flow are selected to complete the network flow transportation. Finally, the service network structure is analyzed and expressed, the service operation under the condition of resource constraint of passenger transport network and the distribution of small piece network flow are considered as a whole, relying on the axis-spoke passenger transport small piece express service network structure. Taking the minimum total operating cost of the generalized service network as the objective function, the constraints of each stage of the service network design are described in detail by using mathematical methods, and the network structure and resource constraints, the service opening constraints and the network flow constraints are set up. Taking the 0-1 variable and frequency of service as the decision variables, the design model of the service network for small passenger express transportation is established, and the design goal of the service network is realized, and the heuristic algorithm is designed. Combined with the case, the paper gives the concrete design scheme of the passenger small piece express service network. The research results of the paper give the integrated design method of the road passenger transport small part express service network design, and refine the service opening and service group selection decision-making process under the condition of the passenger transport network resource constraint. It provides the method support for the design and optimization decision of the auxiliary passenger small part express service network.
