摘要:
The purpose of this paper is by using the shrinking projection method to introduce and study an iterative process to approximate a common solution of split variational inclusion problem and fixed point problem for an asymptotically nonexpansive semigroup in real Hilbert spaces.Further,we prove that the sequences generated by the proposed iterative method converge strongly to a common solution of split variational inclusion problem and fixed point problem for an asymptotically nonexpansive semigroup.As applications,we shall utilize the results to study the split optimization problem and the split variational inequality.%该文的目的是利用收缩投影方法,引入一类迭代程序,并证明该迭代程序强收敛于Hilbert空间中分裂变分包含问题和渐进非扩张半群的不动点问题的一公解.作为应用,在文中还把所得结果应用于研究分裂最优化问题及分裂变分不等式问题.

摘要:
先进的出行者信息系统(简写 ATIS)不仅能帮助出行者获取更准确的交通时间信息,还能提高出行者在面对路网通行能力下降等随机事件时的应急和实时调整能力.本文提出了一类新的混合随机用户均衡模型,用以描述在通行能力随机退化的路网中,装备ATIS和未装备ATIS两类出行者各自的路径选择行为和由此形成的路网交通流均衡状态.在提出的模型中,ATIS 向出行者提供交通信息的优势体现在路网流量均衡分布状态的随机性更低,而ATIS 对出行者适应路网能力随机退化的强化优势,则通过路网流量的多均衡态加以体现.论文将该混合随机用户均衡模型表示成一个关于混合路径流量的不动点问题,并设计了一类迭代求解算法.通过数值算例,论文分析了模型的相关数学特性,并验证了迭代算法的求解效率.%Advanced traveler information systems (ATIS) can not only improve drivers; accessibility to the more accurate route travel time information, but also can improve drivers' adaptability to the stochastic network capacity degradations. In this paper, a mixed stochastic user equilibrium model was proposed to describe the interactive route choice behaviors between ATIS equipped and unequipped drivers on a degradable transport network. In the proposed model, the information accessibility of equipped drivers was reflected by lower degree of uncertainty in their stochastic equilibrium flow distributions, and their behavioral adaptability was captured by multiple equilibrium behaviors over the stochastic network state set. The mixed equilibrium model was formulated as a fixed point problem defined in the mixed route flows, and its solution was achieved by executing an iterative algorithm. Numerical experiments were provided to verify the properties of the mixed network equilibrium model and the efficiency of the iterative algorithm.

摘要:
A metric was defined by using the Hausdorff distance of graphs of set-value mappings, and the bounded rationality was applied to fixed point of upper-continuous set-valued mappings in the sense of graph topology.And it is proven that the most of fixed point problems (in the sense of Baire) are structurally stable and robust to-equilibrium.%本文利用集值映射图像之间的Hausdorff距离定义了度量,在图像拓扑意义下,将有限理性应用到上半连续集值映射的不动点问题,证明了大多数的不动点问题(Baire分类的意义下)都是结构稳定的,对ε-平衡也是鲁棒的.
