Aufbau eines hierarchisch organisierten, wissensunterstuetzten Fertigungsregelungssystems

In the field of manufacturing structures there has been an obvious shift from mass production to a flexible manufacturing of small lot sizes. Moreover the customers have become more and more fastidious as far as a prompt delivery, the speed of reaction and the product quality are concerned. Finally the number of variants of the products to be manufactured has clearly increased. These are the reasons why nowadays much more orders, each with smaller lot sizes, have to be machined. Due to this and to the growing interdependencies within and between the single orders or operations the complexity in the fields of planning and controlling has obviously increased. Besides it became evident, that because of the frequency of the occurring disturbances and the resulting consequences the realisation of the idea of a pure control system with open loop generally does not fulfil the given requests. The present thesis aims at contributing to meeting the customer's requests for prompt delivery, for the producer's flexibility and the quality of the products in the fields of planning complexity and control systems.
