| Changjiang River is open to navigation the condition superiorly, "the golden waterway" the name, southwest, Central China, the East China three big economic zones organic will be connected, the advantageous geographical superiority and the water transportation ability will be playing the role in the region economy cooperation which might not be substituted. Since the reform and open policy, the area in abundance has formulated along the river depends on the Changjiang River opening to the outside world the developmental strategy, below the Changjiang River middle reaches Chenglingji the important harbor constructs the foreign trade wharf;The Changjiang River shipping is day by day prominent in our country opening to the outside world status. In view of the Changjiang River freight transportation large amount goods, the mass freight transportation market development, the Chinese Changjiang River shipping group took our country inland river biggest backbone shipping enterprise group, has organized to Changjiang River to do the bulk cargo many times to transport the market and to do the bulk cargo body form to carry on the investigation and study, carries on the analysis to the market to survey;The shaft coupling refutes the transport mode to carry on the preliminary analysis comparison. Proposed "middle and lower reaches Changjiang River transforms the promotion, matches by the ships and barges primarily, from river boat for auxiliary" transports the strength development plan and the great tonnage, the big formation refutes the fleet the technical proof request.The present paper through the freight transportation market analysis as well as the Changjiang River ships standardization status, draws out the topic which middle and lower reaches Changjiang River the 3000t level barge optimization and the fleet organization plans. The structure optimizes the partial research technique is defers to the structure standard to carry on the structure computation, at the same time transforms the method using the matrix ship which unifies, carries on the 3000t level barge the structural design, the science objectively carries on the analysis, the comparison, the optimization, the appraisal to the 3000t barge structure, obtains the best structural style. When carries on refutes the fleet organization plans the aspect,uses the method which is the full consult correlation literature and the objective reality situation joins, at the same time unifies the long navigation group the actual situation, exchanges the material which looks up obtains to carry on the refinement and the analysis, accurately had understood the ChangJiang River fleet transports the market the present situation and the development tendency. When carries on the 3000t IS level refutes the fleet the efficient analysis, has conducted the system goal optimization research, uses is the multi-objectives decision-making method, established the 3000t level to refute the fleet transportation goal optimization model. When carries on the ships transport business organization way uses is the integer linear programming method, selected the different 3000t level to refute the fleet to carry on the route to match the ship computation, after matched the ship to carry on efficient and the sensitive analysis in view of the most superior fleet.May obtain the conclusion below through this research: Has carried on three kind of structural styles optimization to the 3000t level barge, reduced the barge dead weight, enhances the single ship freight capacity. Refutes the fleet to the 3000t level to carry on the performance computation, through the economic analysis, take reduces the fleet transportation cost and the energy consumption as the goal optimization, obtains best refutes the fleet. Refutes the fleet transportation system for the long navigation group 3000t level barge construction with ChangJiang River middle and lower reaches to plan provides the technical support.
