20090290487 | Communication apparatus and path switching method - 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. | 11-26-2009 |
20100158019 | FRAME TRANSFER APPARATUS AND FRAME TRANSFER METHOD - A frame transfer apparatus includes a plurality of ports for transmitting and receiving frames which include transmitting source information and transmitting destination information. The apparatus further includes a processing unit to store information which relates the transmitting source information included in the received frame and port information of a port which receives the received frame, a frame transmitting unit to transmit the received frame via a port that is identified by the port information which corresponds to the transmitting destination information included in the received frame and is extracted from the information stored by the processing unit, and a learning information erasing unit to erase the information stored by the processing unit for every predetermined time. | 06-24-2010 |

20090157458 | SUPPLY CHAIN EVALUATION SYSTEM, METHOD, AND PROGRAM - Provided is a supply chain evaluation system, in which supply chain planning is formulated according to a simulation time control, and a flow of physical distribution from procurement via production and shipment through a client is simulated based on the supply chain planning, which are repeated during a simulation time. In the supply chain evaluation system, after the supply chain planning and after a physical distribution calculation processing, an inventory volume is calculated for each problem, and presented along with inventory transition. Accordingly, it is possible to obtain effects of SCM measures through a simulation not only in a form of an inventory waveform but also by outputting an inventory volume after calculating the inventory volume for each inventory occurrence factor (problem structure). | 06-18-2009 |
20100057238 | SUPPLY PLANNING SYSTEM, PROGRAM THEREOF, AND SYNTHETIC METHOD - The present invention is directed to a technique to easily establish a supply plan which optimizes multiple evaluation indexes on the basis of the priorities of the multiple evaluation indexes. When the number of evaluation indexes stored in the evaluation index storage area is larger than a predetermined threshold, a processing is repeated for specifying two evaluation indexes from those stored in the evaluation index storage area, and synthesizing the specified evaluation indexes by using a weighing factor, until the number of evaluation indexes becomes equal to or less than the threshold. | 03-04-2010 |
20110276359 | INFORMATION PROCESSING APPARATUS, COST FORECAST CALCULATION METHOD, AND COST FORECAST CALCULATION PROGRAM - An information processing apparatus, a cost forecast calculation method, and a cost forecast calculation program are provided that enable the calculation of cost forecast without cost performance data such as initial inventory and warehousing schedule. The information processing apparatus includes: a reception unit for obtaining production plan data indicating the production plan of a product including date data; a plan change unit that changes the initial inventory data to the production plan data based on the product identification data and the plan identification data; and a cost calculation unit that calculate the cost. | 11-10-2011 |

20150026780 | HOST PROVIDING SYSTEM AND COMMUNICATION CONTROL METHOD - A host providing system includes a physical host network switch which determines permission and non-permission of communication on the basis of whether or not information pieces indicating users correlated with information indicating a transmission source and information indicating a transmission destination included in communication data from a physical instance match each other, and controls the communication data on the basis of a determination result. Accordingly, since only communication between instances of the same user is permitted, and thus communication from a physical instance is appropriately controlled, it is possible to ensure security in the system. | 01-22-2015 |
20150317174 | HOST PROVIDING SYSTEM AND HOST PROVIDING METHOD - A host providing system includes a physical host managing node which controls one or more physical servers and can manage a usage state of a physical host formed in the physical server, and thus the physical server for forming a physical host can be controlled in the system. In addition, a single physical host managing node is selected depending on instance type information included in an instance starting request from a user terminal, and the instance starting request is sent to the selected physical host managing node. Accordingly, it is possible to provide a physical instance complying with a user's request as a physical host. | 11-05-2015 |
