Logic control design and discrete event simulation model implementation for a de-manufacturing plant

In this paper the design of a multi-level control system for a de-manufacturing pilot plant is described. In particular the implementation of the Low Level Control System (LLCS) based on Control Sequences (Sn) has allowed to decouple the High Level Control System (HLCS) from the field, by making the advanced control algorithms development independent from any specific plant technological implementation. The LLCS integrated with the de-manufacturing process have been emulated and modelled into a dynamic discrete event simulator. This approach allows a better automation system architecture definition mainly for Advanced controls techniques
