JFET_V2_N2_RP4 Y. Prasannatha Reddy Dr. G. Ranga Janardhana Journal on Future Engineering and Technology 2230 – 7184 2 2 63 69 Petri Nets, Max-Plus algebra, Discrete Event Dynamic Systems In this paper, a Max-Plus algebra model via the Timed Petri Net (TPN) model for a class of robotic assembly cell is developed. The paper describes the basic concepts of max-plus algebra which can be used for online control of manufacturing systems. In this paper, the given robotic assembly cell problem of assembling two parts using a timed Petri nets, generates a firing sequence for it. The detailed operational sequence for the assembly cell is explained and a reachability matrix for the Petri net model is also given. The complete cycle of the timing diagram required for the maxplus algebra model is presented by plotting a graph between location number and time. Based on the generated firing sequence of the petri net model, a max-plus algebra model is formulated. The formulated max-plus algebra model can be used for online computation and to schedule the operations of robotic assembly cell. November 2006 - January 2007 Copyright © 2007 i-manager publications.
