Design of Real-Time Distributed Manufacturing Control Systems using UML Capsules
In this paper, we describe a general approach for designing real-time distributed manufacturing control systems based on the IEC 61499 (function block) model. We also present two orthogonal methodologies to construct function blocks utilizing UML capsules within an object-oriented framework. In the first methodology we treat a function block as a single capsule, while in the second we model the function block as a component containing multiple capsules. The key difference between these two viewpoints is the granularity of control we have over the function block’s operation and its location within the decentralized manufacturing environment.
