Describing an IMS by a FNRTPN definition: a VHDL approach

A new Petri net extension and a novel method describing the structure and behaviour of an intelligent manufacturing system (IMS), using a VHDL tool, is proposed. The PN extension is defined as Fuzzy Neural Real Time Petri Net (FNRTPN), where the fuzzy part let the intelligent scheduling of the tasks for the IMS, and the neural part calculates the estimation of the parameters of the set point for each resource in the system. At last, VHDL is proposed as an Unified Modelling Language (UML) to express the model of the manufacturing process. The extension and VHDL are used to apply a fuzzy neural control scheme to a FMS.
