Distributed Control of a Manufacturing System with One-Dimensional Cellular Automata

الملخص EN

We present a distributed control modeling approach for an automated manufacturing system based on the dynamics of one-dimensional cellular automata.

This is inspired by the fact that both cellular automata and manufacturing systems are discrete dynamical systems where local interactions given among their elements (resources) can lead to complex dynamics, despite the simple rules governing such interactions.

The cellular automaton model developed in this study focuses on two states of the resources of a manufacturing system, namely, busy or idle.

However, the interaction among the resources such as whether they are shared at different stages of the manufacturing process determines the global dynamics of the system.

A procedure is shown to obtain the local evolution rule of the automaton based on the relationships among the resources and the material flow through the manufacturing process.

The resulting distributed control of the manufacturing system appears to be heterarchical, and the evolution of the cellular automaton exhibits a Class II behavior for some given disordered initial conditions.
