An operation support apparatus acquires a value related to determination on a conditional branch in a PAD from configuration information of an apparatus to be operated, and detects a conditional branch node from the PAD using the acquired value. Then, the operation support apparatus determines whether the apparatus to be operated satisfies a condition indicated by the detected conditional branch node by using the acquired value. Thereafter, the operation support apparatus hides, from the PAD, a branch node when the apparatus to be operated does not satisfy the condition indicated by the conditional branch node.
