Multidimensional Grey Model freight


sllanghai Table 32002 2005 Shanghai predicted value of the goods traffic Tab. redictionoffreighttransportationfrom2002to2005-mslla Table 3 shows, in Shanghai in recent years, freight traffic growth trend year by year. To 2005, freight traffic is expected to reach 556.1 million tons. The formation of the root causes of this growth trend was mainly due to the regional industry in Shanghai sustained and stable development in recent years, and the rapid growth of this industry in the region must make its related materials, components and other production demand, thereby led the region's cargo transportation industry's rapid development. In addition, the region raise the level of consumption has to a certain extent, stimulate commerce,[link widoczny dla zalogowanych], transportation, storage and telecommunications industries and other sectors of development, which make the region as a whole cargo transport volume in Jin years have faster growth. 4 Conclusion The change of the relevant factors affecting cargo analysis and the use of gray correlation analysis to determine the amount of cargo gray incidence order of 2002 to 2005 changes in freight traffic in Shanghai No. 1 Cai Jiaming: Multidimensional gray cargo prediction model to predict 41 *, which can draw the following conclusions: (1) from the gray correlation analysis results,[link widoczny dla zalogowanych], the local area's economic development status, the level of consumption and investment in public transport facilities, cargo area development and change has important implications. Among them, the impact on freight traffic plays a major role for regional economic development status, followed by the consumption level of income for the residents and local public transport infrastructure investment. (2) In cargo traffic forecasts, the use of gray correlation analysis method for the quantitative analysis, from the many factors affecting cargo freight and related factors determine the progression to build cargo transport in the prediction model less impact on the cargo can be removed non-important factor, which simplifies and forecast model. (3) the calculation shows, the use of multidimensional gray prediction theory prediction model built cargo freight area of Shanghai has a good prediction prediction accuracy, in recent years to predict the trend of freight. Comprehensive multi-dimensional model of the Grey (on the next page 37) Figure 6 shows the window by the force and deformation of Fig. 6Interfaceoftheresult3 Conclusion Based on the structure and transport trailer features of bulky cargo, trailer made in the actual loading of the goods may occur when the longitudinal changes in consideration of the many factors affecting cargo, so the forecast on the basis of established model prediction of the amount of cargo, more comprehensive and clear understanding of the growth in freight traffic caused by changes in the underlying causes.
