PURPOSE:To continue the work of another work processing system without switching a host even in the case of completing the work processing system with a high priority order. CONSTITUTION:A group 31 (32) composed of a work processing system 11 (12) of a host 1 and a work processing system 21 (22) of a host 2 has a priority order 41 (42). When the work processing system 11 with the higher priority order 41 is turned to the state of dividing a threshold value, the host is switched. Even when the work processing system 12 with the lower priority order 42 is turned to the state of dividing the threshold value, the host is not switched. When the work processing system 12 recovers the threshold value dividing state, the state is canceled. Even when the work processing system 11 is completed, the host is not switched but the work processing system 12 is continued. |
