Zur Sicherung von Produktionsstandorten in Hochlohnländern wie Deutschland fokussieren sich Unternehmen zunehmend auf die Herstellung von komplexen und kundenindividuellen Produkten. Dies führt zu der Notwendigkeit von flexiblen und gleichzeitig effizienten Produktionssystemen. Im Rahmen des Exzellenclusters "Integrative Produktionstechnik für Hochlohnländer" an der RWTH Aachen wird dazu eine Konfigurationslogik entwickelt, die es Unternehmen ermöglicht, das Produktionssystem derart optimal auszulegen, dass kundenindividuelle Produkte zu Kosten der Massenproduktion hergestellt werden können.
In saturated markets companies have to produce individualized products at low costs. In order to produce the high-variety of products efficiently and to be able to react effectively to order-variations, the production process structures must be most flexible and sustainable. Therefore adaptability of planning processes within the company and the supply chain is a precondition. Moreover an adaptive, decentralized control is necessary, which ensures a synchronized process by a flexible information network across all sub-processes. High Resolution Supply Chain Management aims at designing the production system according to the needs of the company’s supply chain environment.
To reach this goal a consistent research methodology has been elaborated. Based on the Viable System Model (VSM) developed by Stafford Beer current production systems are analyzed preliminary in terms of integrity.
With the gained knowledge a complete recursive model of a Viable Production System is developed. The recursive character of the approach allows identifying independent units within production systems on a detailed level. These units are meant to be self-optimizing control units, whereas the purpose of a unit is to independently optimize its part of the production system or production planning process. The architecture allows modelling a decentralized production system that meets all requirements of a flexible, adaptable production system. Thereupon, research focuses on the development of process and control loops for each of the identified units.
Each unit requires specific input information to be able to achieve a maximum degree of planning accuracy within its boundaries. For the communication of different units a flexible information flow has to be secured. Consequently an additional hierarchical and consistent set of objectives is necessary. Only consistent superior objectives can secure local optimization which yields to something like an overall optimum.
By integrating all results into a complete model of a Viable Production System, the adaptability of planning processes is reached due to the decentralized control of the different units, the consistent set of objectives and flexible information network.
