Risk element information indicating risk elements is acquired. An asset capable of becoming a fault due to a risk element indicated in the risk element information, and a fault probability that the asset becomes the fault are specified based on static configuration information. A risk model in which the asset capable of becoming the fault and the fault probability are associated is generated in advance. In response to a designated input, an one asset to be evaluated is specified as an evaluation target asset, based on the designated input. A risk model related to the evaluation target asset is specified. A risk evaluation value being an index indicating a risk of the evaluation target asset is calculated based on the fault probability of the evaluation target asset and the static configuration information. The risk evaluation value of the evaluation target asset is associated with the asset of the risk model.

Risk management system and method

Example implementations described herein are directed to systems and methods for managing a relationship between real-time analysis processes and applications, where each of the applications are configured to utilize output from one or more of the corresponding real-time analysis processes. In an example implementation, resource adjustment is applied to the real-time analysis process based on a determined priority.

System, method of real-time processing under resource constraint at edge

A network monitoring system compares gathered network information with path information. The comparison between gathered network information and path information provides traceability of automatic and dynamic rerouting function of network and makes it possible to understand the relation between root cause and observed problems. The combined monitoring of data plane with control plane enables identification of the original failure point where behavior is changing though routing failure is propagated around. This will allow the identification of network issues that may lead to service outages and impairments as well as alerting of issues affecting customer satisfaction, and is effective to reduce MTTD (Mean Time To Detect)/MTTR (Mean Time To Repair) and increase service availability in all markets.

Real time transmission monitoring and anomaly detection

Operation management of equipment is made efficient by verifying a plurality of operation management manipulations on a plurality of equipment and optimizing a manipulation order before executing the manipulations. A status of equipment in a status table; a content of a manipulation in a manipulation table; a process time of the manipulation in a manipulation time prediction table; and a status required for the manipulation in the manipulation table are memorized on an operation model managing server. When a plurality of manipulations are input for a plurality of equipment by an operation manager via an operation managing server, correctness of the manipulations is verified and a manipulation order is decided on an operation verifying server based on the various types of memorized information. Also, a manipulation end time of each manipulation is notified to the operation manager via the operation managing server.

Operation managing device and operation management method

Provided is a multiprocessor system and a compiler used in the system for automatically extracting tasks having parallelism from an input program to be processed, performing scheduling to efficiently operate processor units by arranging the tasks according to characteristics of the processor units, and generating codes for optimizing a system frequency and a power supply voltage by estimating a processing amount of the processor units.

Multiprocessor system and multigrain parallelizing compiler

When the multiple sensors monitored by a sensor management unit, input sensor information into the entrance node, a sensor type identifier unit utilizes a buffer management table to buffer the data according to the sensor type. A start decision unit utilizes a processing start setting table containing accumulated start conditions for each application to execute the computation processing required by the processor units for processing the buffered sensor data according to the required application. A transmit condition decision unit decides whether or not to transmit the computation results to an external device or a CPU, and based on those decision results, transmits the computation results to the CPU or the upstream intelligent node.

Node processing device and its processing method

A heterogeneous multiprocessor system including a plurality of processor elements having mutually different instruction sets and structures avoids a specific processor element from being short of resources to improve throughput. An executable task is extracted based on a preset depending relationship between a plurality of tasks, and the plurality of first processors are allocated to a general-purpose processor group based on a depending relationship among the extracted tasks. A second processor is allocated to an accelerator group, a task to be allocated is determined from the extracted tasks based on a priority value for each of tasks, and an execution cost of executing the determined task by the first processor is compared with an execution cost of executing the task by the second processor. The task is allocated to one of the general-purpose processor group and the accelerator group that is judged to be lower as a result of the cost comparison.

Method for controlling heterogeneous multiprocessor and multigrain parallelizing compiler

In case of a task scheduling processing that assigns plural divided execution program tasks to plural processor units, a multiprocessor system using SOI/MOS transistors employs two processes; one process is to determine an order to execute those tasks so as to reduce the program execution time and the other process is to control the system power upon task scheduling so as to control the clock signal frequency and the body-bias voltage to temporarily speed up the operation of a processor unit that processes another task that might affect the processing performance of one object task if there is dependency among those tasks.

Controlling body-bias voltage and clock frequency in a multiprocessor system for processing tasks

Performance of a heterogeneous multiprocessor is reduced as much as possible within a short time without any awareness of parallelization matched with a configuration of the heterogeneous multiprocessor. In a heterogeneous multiprocessor system, tasks having parallelism are automatically extracted by a compiler, a portion to be efficiently processed by a dedicated processor is extracted from an input program being a processing target, and processing time is estimated. Thus, by arranging the tasks according to PU characteristics, scheduling for efficiently operating a plurality of PU's in parallel is carried out.

Global compiler for controlling heterogeneous multiprocessor

To enable an appropriate change of a path according to a situation of a user and a situation of a target store and the path without having a special terminal when the user of a facility utilizes the target store and an appropriate guidance, spatial recognition nodes respectively provided with a sensor and information processing equipment are installed in each location in the facility and connected via a network. The nodes recognize the position, the action and the behavior of a user of the facility. A server controlling a system manages the recognition result and constantly grasps the situation of the user. The situation of the user is recognized by the node installed at a destination and on a path, and notified to the server. The server displays appropriate path information based on the recognition result on any of plural information displays installed in the facility when the user approaches.

in-facility information provision system and in-facility information provision method

Disclosed here is an information processing system capable of recognizing actions and circumstances of a user with respect to both space and time as a 'situation' to recognize the user's request using a plurality of sensing nodes that work cooperatively with each another, thereby responding autonomously to the user's request according to the recognition results. The plurality of sensing nodes and a responding device are disposed in a target space to build up a network for recognizing the situation in the target space. And, a plurality of recognition means are used to recognize the situation with respect to both space and time related to the existence of the user. And, an integral processing portion (master) is selected from among the plurality of sensing nodes, thereby dispersing the system load. If there are a plurality of users, the system can make recognition in accordance with the request of each of those users.
