摘要： In asynchronous processing, processing of a low-order system is checked. A high-order system 1 includes a high-order workflow advancing unit 21 that transmits a processing command for asynchronous processing to a low-order system 2, and a notice processing unit 23 that receives, from the low-order system 2, a notice related to a device command to be executed by a device 3 in the asynchronous processing, and updates progress data 13. The low-order system 2 includes a low-order workflow advancing unit 61 that, upon receiving the processing command from the high-order system 1, transmits a device command to the device, and a notification unit 62 that, when transmission of the device command to the device 3 is detected, notifies the high-order system 1 of the identifier of the device to which the device command was transmitted and the device command.

摘要： [Problem] It is determined whether quick repair handling is required for a failure in a communication apparatus or in a communication service that occurs in a nighttime period in compliance with an SLA while curbing operating expenses.
[Solution] A maintenance task management apparatus 11 determines handling of failures when both an apparatus failure that is a failure in communication apparatuses 46a and 46b in a nighttime period and a service failure that is a trouble in a communication service provided by the communication apparatuses 46a and 46b to users in the nighttime period occur or only the apparatus failure occurs. The maintenance task management apparatus 11 includes a handling determination unit 23 and a handling control unit 31. The handling determination unit 23 determines whether service interruption of communication due to double failures, which are both the apparatus failure and the service failure, violates an SLA that is service level agreement with users when the double failures are detected. The handling control unit 31 performs control for transmitting a quick handling notification for requesting quick failure repair to a worker terminal 42 when it is determined that the service interruption violates the SLA.
