摘　　要：考虑轨道交通接运公交发车间隔及票价的乘客需求弹性,对接运公交系统的成本及收入进行分析,建立了以最大系统总收益值为目标函数、轨道客运量份额为主要约束条件的非线性规划模型,并探讨了它的求解方法。算例结果和参数灵敏度分析表明,优化模型在约束条件内存在局部最优解,系统总收益值随着平均单个乘客等待时间和票价的增加以不同的速度减少,乘客对票价增减的敏感性比对发车间隔增减的敏感性强。The cost and income of the feeder bus system of the rail transit were analyzed in consideration of the elasticity of the passenger demand for the headway and the fare of the feeder bus,and a nonlinear programming model as well as its solution method was proposed taking the maximization of the gross system profit as the target function and the passenger volume share of the rail transit as the constraint conditions.The numerical case study and the parametric sensitivity analysis showed,there is a local optimingation solution of the model in the frame of constraint conditions.The gross system profit gradually decreases in various rates with the increase of the average single passenger waiting time and the bus fare.The sensitivity of the passenger to the increase or decrease of the fare is more strong than that of the headway.
