Modeling of allocation control system of multifunctional resources for manufacturing systems

Abstract

The Manufacturing System (MS) for the fourth industrial revolution, as known as industry 4.0, will be highly flexible in volume production and customization of products. The control system might be able to regenerate the MS in the occurrence of an unexpected event, such as the breakage of a machine. With the evolution of mechatronics systems, machines that have two or more functions in one and the same resource, such as drilling, turning and milling have been developed. These machines are the Multifunctional Machine Tools (MMT). But after the planning step, the MMT are seen as just as one more conventional machine with a single function and the multiple functions contained within it are not exploited, i.e. the functional flexibility of MMT are currently only considered during the production planning phase and encapsulated in that decision-making level. In this work, we proposed a methodology of control system modeling the resource allocation control system that has the capacity to regenerate the MS based on the concept of functional flexibility on the occurrence of an unexpected event such as breaking of a machine by use of the Automated Guided Vehicle (AGV) system. The architecture to regenerate the MS was modeled using a Petri Net (PN).
