(1) Call Admission Control in Mobile Communication NetworksWe have proposed a new call admission control (CAC) scheme for voice calls in mobile communication networks with voice and data traffic, on the basis of the theory for semi-Markov decision processes. Our optimal policy restricts new voice calls in order to minimize the total expected costs (blocking and forced termination probabilities) over a long term.(2) Performance Analysis of the IEEE 1394 Serial Bus InterfaceThe IEEE 1394 interface allows both isochronous transfer mode for real-time applications and asynchronous transfer mode for delay-insensitive applications. We have proposed and analyzed a queueing model to evaluate the waiting time of asynchronous packets affected by the isochronous traffic.(3) Optimal Wavelength Converter Placement in Optical NetworksIn optical networks, wavelength converters are required to improve the efficiency of wavelength division multiplexing. We have developed a genetic algorithm to determine the optimal locations of the nodes equipped with converters. Our algorithm has been applied to realistic networks constructed from the locations of NTT offices in Ibaraki and Kanto areas.(4) Analysis of Queueing ModelsUsing the theory of applied stochastic processes, we have studied several queueing models.

(1)移动的通信网络中的呼叫接纳控制基于半马尔可夫决策过程理论，提出了一种新的用于移动的通信网络中话音呼叫的呼叫接纳控制（CAC）方案。我们的最优策略限制新的语音呼叫，以尽量减少总的预期成本（阻塞和强制终止概率）在长期内。(2)IEEE1394串行总线接口的性能分析IEEE1394接口允许实时应用的等时传输模式和延迟不敏感应用的异步传输模式。本文提出并分析了一个评估异步数据包等待时间的排队模型。(3)光网络中波长转换器的最佳配置在光网络中，波长转换器是提高波分复用效率的必要手段。我们已经开发了一种遗传算法来确定的最佳位置的节点配备转换器。我们的算法已被应用到现实的网络构造的NTT办事处在茨木和关东地区的位置。(4)运用应用随机过程理论，对几种随机模型进行了研究。
