Through analysis the important status of Xi’an international ports zone inpromoting economic and its bus lines current situation, we could find the research pointcut. Xi ’an international port area is one of the key projects in the“11th Five-yearDevelopment Program of Shanxi province", but, the inconvenience of publictransportation is bound to the development of this harbor in the future, and restrict to itsdevelopment. By analysis, this paper discussed using deterministic queuing theorydecision method to establish a rational mathematical model includes passenger flow andplatform number, in order to o analysis and improves public transport conditions in theport zone.Firstly, it introduces the general conditions of Xi’an international ports and itsimportant position in promoting economic development, then from four respects todetailed explain- environmental analysis, data analysis, factor analysis, system analysis.Make the harbor area appears as a vivid concept. Next, the paper analyzes the roadsituation and the number of bus configuration, proposed the suggestion of busoptimization, make preparations to build math model and solve problems.Secondly, use queuing theory to build model. Evaluate several importantparameters in the system, such as: the bus service rate, passengers’arrival rate,passengers’psychological longest waiting time, etc. By the use of mathematical methodto test the distribution of index, then put these parameters into queue model, get in linewith reality conditions and meet the optimal parameters of the system operationcombination.Finally, through the sensitivity analysis, cost - cost of economic analysis and systematic analysis to sum up the conclusion of the model, then discuss the impact ofuncertainty factors on the bus optimization, provide a more effective managementdecision-making method.
