Abstract: A production system including a production line having a series of pieces of production equipment each of which has a parts supply unit. The production system includes: an NC management apparatus that is connected with each piece of the production equipment via a local-area network and acquires therefrom NC data used for operating each piece of the production equipment; and a scheduling apparatus that generates a production schedule and transmits the generated production schedule to the NC management apparatus via the local-area network. Here, the NC management apparatus generates, for each piece of the production equipment, data that is required to perform production according to the production schedule, obtains, for each piece of the production equipment, values that represent differences between current NC data that has been most recently acciuired and the generated data, and outputs the values.

Abstract: Through selecting machines from groups of equipment, determine a line composition for producing a specific product so that a tact time of the line may not exceed an initial set tact time. Give a priority order to the machines based on machines' features, thereby grouping the machines. Store information including the priority order within each group, the priority order between the groups, mounting tact time of the loadable parts, and the tact times proper to each machine into an external storage 1 as control information 2. Supplement the machines according to the priority order to the line composition from the equipment until all the parts are loaded, and calculate the tact time of the line with a CPU 3. Supplement the machines successively from the groups of equipment until the line tact time becomes not more than the initial set tact time. The line tact time is calculated with the CPU 3.
