This paper presents an approach to build supervisory systems for complex continuous production processes. Local controllers perform local supervision tasks, and they are able to communicate with central systems where the coordination for the whole process is performed. Local controller's architecture supports several software components, which perform supervision, monitoring, control activities, and communicate with a supervision center to ensure the coordination of the whole process. At the supervision center, a software architecture has an abstraction of local processes and is able to achieve production reconfiguration, for optimizing, taking into account the changes generated on the processes.
