摘    要:通过对城市公交线网的优化原则、优化目标以及约束条件的分析,提出公交线网优化目标的函数表达式及相应约束条件的数学表达式.在考虑城市公交线网各因素的基础上,利用有关数学方面的知识,建立了城市公交线网优化的线性模型.由于运筹学中的逐步法是一种迭代法,适合于多目标优化问题,所以用逐步法对建立的优化模型进行求解,得到能够满足城市公交线网优化需求的解,并且得到的解与实际生活比较接近.

关 键 词:公交线网  线性模型  优化  逐步法

Abstract:Through the analysis of optimization principle, optimizing goal and restricted conditions of urban public traffic line network, optimization function expression and corresponding conditions are presented.By considering each factor of urban public traffic line network and by utilizing relevant mathematics knowledge, a linear model of urban public traffic line network is set up. With the step-by-step method the optimization model is solved. The solution can meet the demand of optimizing urban public traffic line network, and is close to the real situation approximately.
Keywords:public traffic line network  linear model  optimization  step-by-step method
