Patent ID: 7221983

Claim:
A production cell, comprising: a plurality of work performing elements for performing work; an information processing device for commanding work tasks, connected to the respective work performing elements by communications means, wherein: said information processing device outputting a command consisting of a set of task units assigned with an execution sequence, to each of the work performing elements; the work performing elements each storing operating programs for respectively executing one or more task units, and performing work by executing the operating programs in the order of the execution sequence, on the basis of the set of task units with an assigned execution sequence output by said information processing device; and the information processing device receiving notifications for executability of specific task units from the work performing elements, and based on the received notifications, selecting one of the work performing elements to execute the specific task unit, wherein the work performing element notifying the information processing device that execution of one of the task units is possible sends a task efficiency value of the executable task unit, and wherein the information processing device selects one of the work performing elements having sent a notification that the task unit is executable and sends an execution command to the selected work performing element, upon which the selected work performing element executes the task unit, based on receipt of the notifications that task units are executable and the task efficiency values from the work performing elements.
