Information-Based Coordination of Production Orders
The Production Control unit investigates concepts of production control in combination with methods of data analysis and Industrie 4.0. The term "production control" refers to the transfer of the principle of the control loop to the planning and control of production orders. The control system attempts to return the system to a stable state and to keep possible effects of malfunctions as low as possible and, if necessary, to reverse them.
The concept of production control
Regardless of whether a company manufactures individual customer orders or series products: With increasing variant diversity, shorter product life cycles, and decreasing batch sizes, the number of decisions to be made on the shop floor is increasing. This is due to deviations and malfunctions in increasingly complex production systems and networks. We develop and investigate strategies for coping with this flood of decisions, taking into account current technological developments. The vision is to set up a production control system, i.e. to link data acquisition and data analysis with production control concepts. This concept takes its cue from the control cycle and extends control by a component in order to stablilize the processing and completion of production orders. The effects of a possible malfunction is thus to be minimized. The concept is targeted at the areas of scheduling, i.e. the dispatch of orders according to various criteria, work preparation, personnel resource planning, and production controlling. The work of these departments is characterized by a continuous evaluation and monitoring of the actual state compared to the target state. Any identified deviations are automatically taken into account in future decisions, where possible, and may lead to changed input data for future planning. In addition to the PPS software for production planning and controlling, in recent years, Manufacturing Execution Systems have established themselves on the market, which contain a range of tools for monitoring and controlling production orders as well as for the preparation of data.
Production Control: Research Fields
The unit's research activities can be classified with the help of an ordering framework with two dimensions: On the one hand, the applicability and further development of established concepts for order monitoring and production control are being investigated. On the other hand, regarding production control, FIR investigates process models and application cases for the evaluation of manufacturing order data. A synthesis of these research streams is to result in a model of production control.
