Hierarchical modelling of manufacturing systems using discrete event systems and the conflict preorder

This paper introduces Hierarchical Interface-Based Supervisory Control using the Conflict Preorder and applies it to the design of two manufacturing systems models of practical scale. Hierarchical Interface-Based Supervisory Control decomposes a large system into subsystems linked to each other by interfaces, facilitating the design of complex systems and the re-use of components. By ensuring that each subsystem satisfies its interface …
