PURPOSE:To realize the flexible control of the follower groups and users and at the same time to avoid the improper control, by controlling each group in a hierarchical tree structure. CONSTITUTION:The control power to a user U1 is given to a controller M11 of a relevant group G11, a controller M10 of a higher rank group G10, and a controller M00 of a group G00 higher than the group G10 respectively via a higher rank group controller check processing part 13. At the same time, a controller M20 of a group G20 belonging to another series is inhibited from controlling the user U1. In case, a user U2 of the group G20 is shifted to the group G11, the shift to be carried by the controller M00 is allowed via the check of an intersecting point check processing part 14. While said shift to be carried out by a controller M10, for example, is not allowed. |
