Research Of Railway Special Freight Logistics Network And Operative Mechanism

As the infrastructure of the country and the artery of national economics,the railway plays a forceful drive of transportation for China's economics.Railway is the preferential transport means,according to its advantages of large volume,low cost, protecting environment and saving energy.Track transport is a green traffic,which is supported by governments at all levels.However,the focal points of China railway,the organization mode of which still stays at planned economics age,is to transport key resources of the country,such as coal,food and steel.Therefore,China railway is still a pure transportation enterprise.Nowadays,logistics industry becomes the pillar industry of world economics development.Railway reform from simple transport into logistics network is called out by society at all levels.Railway should play its synthesized advantages to improve modern logistics industry.China railway pay more attention to the logistic development,The special freight logistics is been a sign for railway developing logistics service,Which is supported by policy and investment.Therefore,the article researches on railway special freight logistics network and operative mechanism,to get new way for railway specific cargo logistics from transportation to logistics service.The main content and new ideas of the article is as follows:A.The article analyzes the meaning of Railway special freight Logistics Network and current situation and problem of railway freight development home and abroad,form its concept,and expounds the meaning and operational mode of railway logistics.It puts forward that networking railway logistics is the way to develop railway logistics industry,implementing main client management is the useful way to form the network,and setting up hub and spoke model logistics network is the method to develop the network.B.The article study special freight Logistics for satisfy refrigerated logistics and car logistics,and sums up operative mechanism of railway specific cargo logistics network.It put forward that forming organization network,infrastructure network and information network of railway specific cargo logistics,Process re-engineering is the base way.C.Specific vehicles adjustment is the key point of the railway specific cargo logistics network.The article sets up network flow and operational route choose model by using network flow and optimize theory,provides its arithmetic way and gives the idea of improving constraint conditions of the model.Ant Colony Optimization is a new heuristic arithmetic of imitating ant work means,The article uses ACO to solve refrigerated vehicles preparation optimized model.The results indicate the feasibility of the arithmetic.D.Railway specific cargo logistics should be completed under special safeguards measure,So that it is important to establish it.As railway specific cargo logistics network is a huge system,it is necessary to set up unified technological rules and standards,technology safeguards system,to research its transport modes, communication means,computer system,special cargo freight standard and emergency measures.It gives some ways to protect safety of the network on the basis of railway transportation network.
