<p>PURPOSE:To add and correct easily each equipment by determining the equipment, to which a work should be assigned, by an equipment group controller on the basis of evaluated values from individual equipment controllers for the next requested work. CONSTITUTION:Information indicating that a work A is completed is sent from a station controller 201 to a group controller 204. The controller 204 determines the next requested work B on the basis of this information and sends this work B to individual controllers 201. Each controller 201 takes in information of this work B and judges whether the work B can be executed or not; and if it can be executed, evaluated values of the predeterminate time of the start of the work B or the like are calculated, and the results are sent to the controller 204. The controller 204 determines the controller, to which the work should be assigned, on the basis of these evaluated values and sends a work command to this controller 201. Since loose connections between the group controller and individual station controllers are realized by this constitution, equipments are added and changed easily.</p> |
