The system includes sensing means 120 for detecting a state of a space; a
robot 102 for executing a handling job for an article; an article
identifying part 32 for identifying, when an article is handled by a
movable body, the article in response to a detection result obtained by
the sensing means 120; and an article handling subject identifying part
33 for identifying an article handling subject that handles the article.
When the movable body that handles the article is the robot 102, the
article handling subject identifying part 33 identifies a subject having
issued a job instruction to the robot 102 as the article handling
subject.
