Abstract: [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.
