    • The congestion in a network can be avoided by effectively utilizing a prepared network band even in a network where reception intervals of acknowledgments are not correct. According to the information about Ack or Sack (selective acknowledgment) received in a time of the minimum value of an RTT (rtt_min), the number of bytes of received segments (rcv_bytes) for which a receiving side acknowledges the reception is counted, and a received byte number setting unit 16 sets a congestion window (CWND) or a slow start threshold (SSTHRESH) when a packet loss occurs according to the number of bytes of received segments (rcv_bytes) counted by a received byte number counting unit 14 when a packet loss is detected by a loss detection unit 15.
    • 即使在确认的接收间隔不正确的网络中也可以有效利用准备的网络频带来避免网络中的拥塞。 根据在RTT(rtt_min)的最小值的时间内接收到的关于Ack或Sack(选择性确认)的信息,接收侧确认接收的接收段(rcv_bytes)的字节数被计数,并且 接收字节数设定部16根据接收到的字节数计数部14的数据的字节数(rcv_bytes),当发生分组丢失时,设定拥塞窗口(CWND)或慢启动阈值(SSTHRESH) 由损失检测单元15检测到损失。

    • In a communication apparatus on a network having ring topology and connecting plural communication apparatuses such that adjacent communication apparatuses are connected through plural lines, a first detecting unit detects failure occurring in a line included in a relay path set between the communication apparatus and another communication apparatus on the network. When the first detecting unit detects failure, a switching unit switches the relay path to a relay path connecting the communication apparatuses on the network in a direction opposite to the relay path originally set. A second detecting unit detects failure occurring in a line included in the relay path switched to by the switching unit; and when the second detecting unit detects failure, a resetting unit resets the relay path using a line where no failure has been detected.

    • A production plan is created so as to minimize risk of demand variations. Forecasted values of amounts of requests are entered for each different item of products, markets, dates, past accuracy of demand forecasts, and order achievements at the time when the plan is created. Scenario information is created in which assumable amounts of request for each different item of the products, markets, and dates and probabilities at which the amounts of requests agree with actual amounts of requests are defined. Management indexes are found from the amount of stockout and amount of stock calculated in each different scenario, based on the scenario information, target values of the management indexes, and information on strongpoints. An amount of production that maximizes the achievement ratios of the management ratios to their targets within the ranges of supplied materials and within the range of the production capacity is calculated by an optimization algorithm.
    • 创建一个生产计划,以最大限度地减少需求变化的风险。 对于产品,市场,日期,需求预测的过往准确度以及创建计划时的订单成绩,都会为每个不同的产品项目输入需求量的预测值。 创建情景信息,其中定义了产品,市场以及请求数量与实际请求数量一致的日期和概率的每个不同项目的可预测数量的请求。 根据场景信息,管理指标的目标值和强点信息,从各种不同场景中计算的库存量和库存量中找出管理指标。 通过优化算法计算了在供应材料范围内和生产能力范围内使管理比例达到目标的最大化生产量。
