摘要： PROBLEM TO BE SOLVED: To restrain increase of process load of a center, in the case of simultaneous concentrating of notifications to the center, when service interruption is recovered, in a computer network system.
SOLUTION: A representative node in a group is previously decided for a network elements which are in a relation of a master and slaves. Rather than each of the nodes directly notifying a master node but notifies the representative node in a group. The representative node awaits, to receive notification inside the group for a specified period or a specified amount of receiving from first receiving of notification, collects notifications from a plurality of slave nodes, and informs the notifications. When information notifications are generated all simultaneously, from the slave nodes to the master node, since the representative node arranges a plurality of the notifications and informs them to the master node, communication load in the master node can be restrained.

摘要翻译：要解决的问题：在计算机网络系统中，为了抑制中心的处理负荷的增加，在同时集中通知到中心的情况下，当恢复服务中断时。解决方案：组中的代表性节点先前针对与主机和从机关系的网络单元。而不是每个节点直接通知主节点，而是通知组中的代表节点。代表节点等待，在第一次接收到通知的情况下接收组内指定时间段的通知或指定的接收数量，从多个从节点收集通知，并通知通知。当从从节点到主节点全部同时生成信息通知时，由于代表节点排列多个通知并将其通知给主节点，因此可以抑制主节点中的通信负载。

摘要： PROBLEM TO BE SOLVED: To correct a similar phenomenon abstracted at the time of forecasting and estimating a demand for the supply of an energy flow, with a correcting method adapted to the condition change of an element that relies on the human life. SOLUTION: A resulting DB 13 is obtained from an influential-factor forecasting data 2 and an influential-factor resulting data 3, and a forecasted-factor data table 14 on a forecasting data is also obtained therefrom. The factor includes at least 9 kinds of the days of Sunday to Saturday, a feast day and a special day. MBR function 15 abstracts a plurality of similar days checking the degree of similarity of the data of the forecasted factor and the output of the resulting DB, and NN function 16 calculates a corrective figure of a demand of these similar days by a neural network set on each day. A compound function 17 corrects the resulted supply volume of each similar day with the corrective figure, and after that, outputs the average of a corrective supply volume of all similar days as a forecasted and estimated figure.

摘要： PROBLEM TO BE SOLVED: To monitor a state and to decide abnormality with higher precision by adopting a multivariable space including many relative variables by plotting variables in the multivariable space in consideration of relative time delay. SOLUTION: The number of the dimensions of the multivariable space is inputted through an input device 104 and stored in a dimension number storage part 105. Reference variables of respective variables and time delays are inputted from the input device 104 by as many as the dimensions stored in the dimension number storage part 105 and stored in a time delay storage part 108. A normal area stored in a normal area storage part 111 is displayed on an output device 110. Data are delayed by times stored in the time delay storage part 108 by the respective variables are obtained from the data in a time-series data storage part 103 and outputted to the output device 110. When a decision is made, which of M×N a plotted point is calculated to judge whether or not it is a block in a current normal block.

摘要： PROBLEM TO BE SOLVED: To prevent the contents from being hidden behind an in-line display menu when input data is selected in the pull-down menu on a data input picture in FIF(File In the Form) form. SOLUTION: A document display means 15 reads out and displays a notice document in FIF form completed by embedding data in blank columns from a document information storage means 11 and a menu display means 18 makes a pull-down display of corresponding menu information in the in-line form corresponding to a blank column position instructed by a input means 20. A document display position control means 13 and a document display property control means 14 receive the menu display position from a menu display position control means 16 and change the property (line spacing) and display position of a notice sentence overlapping with the menu, e.g. inserts carriage returns corresponding to menu height, thereby controlling the document display so that the document information will not be hidden behind the menu.

摘要： PROBLEM TO BE SOLVED: To surely derive an exceptional rule by improving a covering rate by making an instance modulus by separating an instance meeting the condition of the condition part of a general rule. SOLUTION: Instance data, categorized information, a rule acquisition condition for exception rule acquisition are inputted from an input device 10 and stored in an instance data storage device 21, an instance data categorizing device 22, and a rule acquisition condition storage device 24. The condition part of the general rule on which the exceptional rule is based is used as a condition for narrowing down object instance data of exception rule acquisition and instance data meeting the condition is separated as an instance for the exceptional rule acquisition. Further, an attribute value which has the same attribute name with the conclusion part of the general rule and is different is generated as an exceptional rule conclusion part. A search for the exceptional rule conclusion part generated as to the separated instance is instructed to perform rule acquisition, thereby acquiring the exceptional rule to the specified general rule.
