Abstract

The invention belongs to the technical field of multimodal transport service network optimization, and discloses a preference degree-based multimodal transport service network optimization method, which is an experimental method for discrete selection experiments (DCE) by taking transport price, transport time, transport frequency, transport reliability and transport safety as service attributes.Three problems of service type optimization, service path optimization and transfer process optimization are taken as main contents. The operation cost, the transportation cost, the transfer operationcost and the preference-degree-based service value cost of the service are used as constituent elements of the total cost of the service network. The multimodal transport service network collaborative optimization model with line capability constraints is constructed, and the service frequency representation method is processed in combination with the characteristics of the model, so that the solving difficulty of the model is reduced, and solving of the multimodal transport service network collaborative optimization model is realized.

Description

technical field [0001] The invention belongs to the technical field of multimodal transport service network optimization, and in particular relates to a preference degree-based multimodal transport service network optimization method. Background technique [0002] At present, the closest existing technology: multimodal transport is not a simple combination of different modes of transport, but as a type of comprehensive transport system, covering a variety of different modes of transport, and through the transfer operation link, to achieve the mutual connection of different modes of transport , Continuous operation, providing customers with integrated transportation service solutions. [0003] However, in the process of actual transportation organization, due to the low coordination efficiency of different transportation methods in the transit link, the multi-modal connection is not smooth, forming service islands, and an integrated transportation service system has not yet b...
