Abstract: A method, computer program product, and system that discards unneeded elements when generating a fault tree of an object to be analyzed. Configuration information identifies a plurality of functional blocks comprised by the object and a plurality of signal lines that connect the functional blocks in logical relationships. Exclusion target information identifies a signal line that may be excluded from the plurality of signal lines without loss of information or a functional block that may be excluded from the plurality of functional blocks without loss of information. Exclusion of a block or signal line may be determined by detecting a redundant functional block or by detecting a circular signal path traversed by two or more signal lines. The generated fault tree omits the excluded block or signal line and identifies the existence of a redundant block or of a circular signal path.

Abstract: A system management apparatus and method adapted for use in a network system that comprises a plurality of devices such as computers connected via a network, whereby it is possible to automatically manage device information unique to each of the devices in association with users of the devices and subordinate organizations that possess the devices. The system and method additionally allow for automatically creating a database for managing device information of each device that constitutes a network system, thereby reducing system administrator's efforts required for system management operations.

Abstract: A network system 1 transmits data between a management apparatus 2 and managed devices 3 each connected to a communication network, processes the data, and displays resources of the managed devices 3 in association with users and/or organizations of the managed devices 3, thereby to support system management operations. That is, in the network system 1, the management apparatus 2 displays an organizational map in a tree form that shows employee numbers of users who belong to each subordinate organization (division/section) that makes use of the system in association with an identifier of such a subordinate organization, displays users who belong to a designated subordinate organization in association with the users' managed devices 3, displays resources of a designated managed device 3, and causes the designated managed device 3 to execute a process using its resources.
