Description
Summary:Conventional production control methods are normally based on static models. Therefore, they are insufficient for mastering the increasing dynamics in the companies' environment. In order to solve the problem, this paper aims to present a new general concept for dynamic modelling of job shop productions using methods of control theory. This concept for the medium-term planning level is based on a feedback control with defined reference and control variables. The developed distributed backlog controller eliminates an arising backlog as fast as possible by means of flexible capacities. Simultaneously, a central WIP-controller guarantees a defined WIP level within the shop by controlling the total input rate into the job shop. Finally, the logistical rationalisation potentials of Automatic Production Control are pointed out by means of an industrial case study.
