Research On Selection Of Vehichle For Freight Loading In Distribution Center

As the advantaged logistics technologies applied and practiced in the enterprise of china,as the first link in modern logistics the transportation develops rapidly in china,it contributes a lot to the development of the logistics.And the improvement of the road infrastructure will accelerate the development of ehina's road transportation industry,the requirement of the road transportation increases ceaselessly,and it also ask a lot to the characteristics of the transport vehicles.Such the vehicles are the carries of the transportation,which relate to the transportation capability,quality and safety,but in a long term,people used to believing that the transportation is the transportation and the vehicles are the vehicles,just thinking about how to transport the goods to the destination,and rarely treated the transportation,vehicles and the related facilities as one whole research object,the idea to connect the transportation vehicles and the supply chain are less referred to the problems which help understand the high cost and the low efficiency and the uncertain quality of the transportation.Therefore,we should not only focus on the transportation management and distribution,but also on the integration and the coordination of vehicles and logistics.According to the characters of the cargo,then to choose the proper vehicles and the route,all of these lead to a win-win situation in logistics.In the first place,the factors of the cargo loading problems are analyzed in the article,including the systemic analysis of the cargo,vehicle distribution center,customer,the constraint conditions and the objective function etc.In the second place,the four aspects of the distribution are explained according to the characters and requirement in the logistic system,such as the kinds of the transportation vehicles,operation process,the principle of the tally and loading,distribution net work.According to such the theories and the average research,the AHP model is applied in the analysis,including three aspects that are transportation economic,transportation speed and transportation safety,such the analysis tends to select the proper cargo vehicle and to design the model for the selection and evaluation of the cargo vehicle,which combines the quantitative analysis and qualitative analysis. According to the different characters of every evaluation,the dimensionless method is applied to standardize and regulate the evaluation data,and the statistical Spearman rank correlation coefficient is brought in to analyze the reliability of the dimensionless method.In the end,with the example of the M company group and the A distribution company,the model for the cargo vehicle choice and evaluation is proved,it is scientific and practical and the optimum plan could be given by this method.
