China's railways begin to handle transportation of the piece goods in large scale from the 20 th century to the 50 th century, and the transportation mode of the piece goods, the operation mode of the piece goods train and the like are continuously adjusted to adapt to the continuously changing market situation. Due to the continuous decline of the transportation amount of the railway freight with part loads and the tense of the railway transportation capacity, the railway gradually cancels the transfer of the goods with part loads from 2006. Along with the continuous optimization of a railway network, the railway transport capacity is released, and along with the development of the economic society of China and the adjustment of an industrial structure, an economic structure and a product structure, the logistics market demand is changed greatly. Under market conditions, the goods transportation demand is changed from the original mode of single variety, large batch and weak timeliness to the mode of multiple variety, small batch and strong timeliness, and the goods flow structure is developed towards the direction of scattered white goods. However, the railway has obvious insufficient competitiveness in the aspects of timeliness, convenience and the like in the aspect of bulk white goods transportation, and most of market share is occupied by road transportation. Therefore, railway transportation must actively expand the sources of scattered goods, and the development of railway logistics industry is promoted by improving the service level of railway transportation.
The invention aims to adapt to the change of supply and demand relations of railway transportation markets, fully exert the advantages of large railway transportation capacity, high speed, environmental protection, continuity, stability and the like, make up the problems of weak railway transportation cargo collection capacity, narrow customer resource range, low market coverage rate and the like, contribute to improving the railway service competitiveness and reduce the social logistics cost.
Disclosure of Invention
The invention aims to overcome the problems that the research and analysis of the requirements of railway freight transportation and logistics markets in the prior art result in that certain defects exist in the cooperative management of the railway freight collection and distribution technology, and provides a cooperative management research method for the railway freight collection and distribution technology, which is beneficial to reducing the social logistics cost.
In order to achieve the purpose, the invention provides the following technical scheme: a railway part load cargo collection and distribution technology collaborative management research method comprises the following steps: comprises the following steps;
step one, summarizing the characteristics of railway part load collection and distribution, and combing the key problem of road-rail cooperative service in the railway part load collection and distribution process; different cargo collection modes such as opening a small-running train for cargo collection and collecting cargos through a highway logistics enterprise are researched, a railway logistics enterprise and a service mode of collecting and distributing cargos in the first kilometer and the last kilometer are designed, and the cargo collection and distribution process is optimized;
secondly, the main status of the railway transportation in the collection and distribution of the part cargos and the cooperation of the railway logistics enterprises and other logistics enterprises are fully considered, the collection and distribution of the part cargos of the railway are considered in a combined manner, and the problem is abstracted into a vehicle path problem mixed with the collection and distribution for optimization; meanwhile, the key linking effect of a railway logistics center and a freight station in the process of collecting and distributing the piece goods is considered, and a railway logistics center or a freight station covering a certain area is scientifically decided by adopting a coverage site selection model; carrying out integrated optimization on the goods collection and distribution problems of the 'first kilometer' and the 'last kilometer' and the coverage problems of a railway logistics center and a freight station, establishing a mixed integer programming model, and designing a mixed tabu search algorithm for solving;
and step three, the logistics center or the freight yard station does not fix the coverage range, the current day coverage range of the logistics center or the freight yard station is determined through integrated optimization based on the cooperative coverage problem and the vehicle path problem according to the actual situation of the centralized distribution, and meanwhile, the railway piece goods is distributed and distributed in an optimized mode.
The first step is railway part cargo collection, distribution mode and flow analysis.
And the second step is the research of a coordination-based optimization method for the collection and distribution of the piece goods.
And step three, developing a railway part load goods centralized cooperation technology based on dynamic coverage.
Compared with the prior art, the invention provides a railway part load cargo collection and distribution technology collaborative management research method, which has the following beneficial effects:
1. the invention is beneficial to reducing the carbon emission and energy consumption of transportation of the whole society, the carbon emission of the unit turnover quantity is reduced by 0.38% when the railway turnover quantity accounts for 1% in China, and the application researches and can promote the multi-type intermodal proportion taking railway transportation as a main body and reduce and improve the environmental pollution problem caused by road transportation;
2. the invention is helpful for reducing traffic jam and traffic accident rate caused by trunk truck transportation, and the road transportation is changed to railway transportation, thus being helpful for reducing the driving accidents and death rate of the trunk transportation and reducing the traffic jam of the expressway;
3. the invention is helpful to reduce the social logistics cost, currently, the railway transportation cost is about half of the road transportation cost, and the project research is helpful to improve the railway service competitiveness and reduce the railway operation cost.
