“…The finite deterministic automata describing the product transfer between the machines installed on the same floor, namely the horizontal material handling system, will be presented. The automata are in accordance with the model of the single floor manufacturing process presented in [12]. On the ground floor being the input/output floor, there are no manufacturing machines and stations.…”

“…The robotic platform delivers the products from the output station of a machine to the input station of the next machine, the delivery process is concluded when the terminal switch is activated. The automaton of the i-th floor is of the form of the 6-tuple (for 6-tuple automata, see [12,13,15,19,20]):…”

“…Discrete event system (DES) approaches are offered for this goal. DES approaches have already been used to model and control single level production machine chains (indicatively, see [10][11][12]) and elevator systems (see [13,14]). To the best of our knowledge, the coordination of the handling material system for MFM processes has not as yet been studied through DES point of view.…”

“…The multi-floor system is modeled using finite deterministic automata. The automata that model the product transfer on every floor and the automaton that models the elevator system are in accordance with the respective models presented in [12] for a single floor manufacturing process and [13] for a mining process elevator system. The coordination of the MFM process is analyzed into a set of desired languages and is accomplished through the development of a modular supervisory design scheme.…”

Due to space availability limitations and high land costs, there is an increasing development of multi-floor manufacturing (MFM) systems in urban and industrial areas. The problem of coordination in a multi-floor manufacturing process, in the Ramadge Wonham framework, is introduced. The manufacturing chain of each floor and the elevator system are modeled in the form of finite deterministic automata. The models of the multi-floor manufacturing process are parametric with respect to the number of floors and the number of manufacturing machines on each floor. The coordination desired performance is formulated in the form of desired regular languages in analytic forms. The languages are realized by appropriate supervisors in the form of finite deterministic automata. The models of the supervisors are also parametric with respect to the number of floors and the number of manufacturing machines on each floor. The total control of the coordination of the multi-floor manufacturing process is accomplished via a modular supervisory control architecture. The complexity of the supervisors as well as the complexity of the total modular supervisory architecture are determined in analytic forms with respect to the number of floors and the number of manufacturing machines on each floor. The special case of a two floor manufacturing process is presented as an illustrative example.
