decentralized manufacturing control systems; real-time reconfiguration; UML capsule stereotype; reconfiguration en temps réel; stéréotype de capsule UML
In this paper, we describe two orthogonal methodologies for building decentralized manufacturing control systems. The fundamental building block of these control systems is the UML capsule stereotype that can be used to design object-oriented software systems that are open, agile, have capacity to manage real-time tasks and so can provide varying degrees of "intelligence" within a 21st century manufacturing environment. We also critique and evaluate the merits of these two viewpoints with respect to how responsive the manufacturing control system is to requests for reconfiguration.
