Abstract:
A cooperative management system for causing a plurality of individual systems to operate in cooperation with each other as one overall system has a search unit that searches for and decides conditions of individual indicators or operating parameters which will improve an overall indicator, by using a relational model. The relational model represents a relationship between an overall indicator which is an evaluation indicator regarding the overall system, and the individual indicators which are evaluation indicators of the respective individual systems, or the operating parameters of the respective individual systems for controlling the individual indicators. Also, the cooperative management system has a notification unit that notifies the respective individual systems of the conditions of the individual indicators or the operating parameters which are decided by the search unit.
Abstract:
The risk management system includes countermeasure information indicating a relationship between each of a plurality of risk types and a countermeasure against each risk type, and a plurality of risk models that define a process of estimating a risk value at each point of time in future and determining a countermeasure, the plurality of risk models corresponding respectively to the plurality of risk types, selects a risk model corresponding to a risk type of each of the constituent elements, gives result information to the selected risk model to estimate a future risk value of each of the constituent elements, and, according to the risk model, extracts a countermeasure corresponding to the risk type, based on the countermeasure information. The risk management system includes also risk structure information defining a countermeasure for the management target and a threshold for applying the countermeasure.
Abstract:
There is provided an autonomous distributed type file system which is connected to a data reference device through a first network. The autonomous distributed type file system includes a plurality of storage device units which are mutually connected through a second network and are connected to the first network. Each of the storage device unit includes a local storage and a local controller. The local controller includes a storage directory and a duplicated data maintaining unit. The duplicated data maintaining unit refers to the storage directory, and continuously keeps same contents of duplicated data items in a range without running out of storage capacity of an own node. When there is no free space in the storage capacity, duplicate writing of the data with the same contents is prevented.
