Claim 0:
1. An alarm management apparatus comprising:
a storage; and
a processor configured to at least:
present a trigger alarm indicating an original cause of an abnormality to an operator by an operation monitoring terminal when the trigger alarm is included in an alarm that is received or generated;
store, in the storage, a suppressed alarm indicating a secondary process abnormality due to the process abnormality that caused the trigger alarm, without presenting the suppressed alarm to the operator, when the suppressed alarm is included in the alarm;

additionally present the stored suppressed alarm to the operator based on an operation by the operator to the operation monitoring terminal,
determine whether the suppressed alarm is effective for resolving the trigger alarm based on an operation history of a recovery operation by the operator or a response by the operator in a dialog box inquiring whether a particular suppressed alarm is effective for resolving the trigger alarm; and
when the suppressed alarm is determined as effective for resolving the trigger alarm, change a control logic so that even when the suppressed alarm is included in the alarm, the suppressed alarm is subsequently presented to the operator together with the trigger alarm without the operator performing an operation to the operation monitoring terminal.
