HIMAC - Hierarchical Management and Control in Manufacturing Systems
نویسندگان
چکیده
Various methods for controlling manufacturing systems have been proposed, but until now the problem could not be considered as being solved. This may be due to the lack of a sound mathematical foundation. Therefore, an algebraic modelling method to describe manufacturing systems is developed. The result of this system modelling is a state equation which can be used for the design of closed loop feedback control systems. This paper is structured as follows: As an introduction, the need for this new modelling approach is justified. Next, the manufacturing algebra and the equation for factory dynamics are described. An example serves to illustrate the theoretical considerations. Finally, the structure of the HIMAC simulation test bed is presented. It implements the theoretical model and facilitates the execution of various test cases.

متن کاملOptimal and Hierarchical Controls in Dynamic Stochastic Manufacturing Systems: A Survey
Most manufacturing systems are large and complex and operate in an uncertain environment. One approach to managing such systems is that of hierarchical decomposition. This paper reviews the research devoted to proving that a hierarchy based on the frequencies of occurrence of different types of events in the systems results in decisions that are asymptotically optimal as the rates of some event...
