Current automation systems need to be able to cope with the continuously changing requirements of the applications in terms of complexity, extensibility and dynamism. To match these challenging requirements, modern automation systems need to incorporate new software engineering techniques. These techniques must provide to the automation systems additional abilities such as diagnosis and reconfiguration...
Shortening product lifecycles and small lot sizes require manufacturing systems to adapt increasingly fast. Many existing machine tools, handling and logistics systems are already generic and not bound to a specific product a-priori. Yet this flexibility and reconfigurability on the asset level is lost in automated systems that are limited to executing a small set of predefined actions in a fixed...
Future manufacturing systems have to be more adaptable to be able to compete in fast changing markets and address specific customer demands. To increase adaptability of production systems, the software and communication infrastructures have to be adaptable as well. Current communication paradigms tightly couple manufacturing systems to communication infrastructures. Changes in the manufacturing system...
This paper proposes a method for real time diagnosis against product quality drifts in an automated manufacturing system. We use Logical Diagnosis model to reduce the search space of suspected equipment in the production flow, which is then formulated as a Bayesian network to compute risk priority for each equipment, using joint and conditional probabilities. The objective is to quickly and accurately...
Modularization aims to improve the flexibility and reconfigurability of manufacturing systems. But the effort and complexity required for the coordination of modules increases with the distribution of intelligence. One of the challenges is the identification of subsystems or automation components in modular manufacturing system which is the focus of this paper. The complete identification of a component...
The integrated analysis of quality and production logistics in manufacturing systems has recently attracted increasing interest among researchers and industrialists. It has been shown that several links exist among the manufacturing system design and the product quality, which are dominated by complex dynamic interactions. However, these interactions have never been addressed in manufacturing systems...
