The paper presents the effect of repair facility on the availability of a rubber component manufacturing system using generalized stochastic petri nets (GSPNs). The GSPN model is based on a rubber manufacturing plant located in North India. The subsystems include mixing mill, planner, strip cutter, molding machine, buffing machine, washing, and packing and sealing units. GSPN was developed using GRIF petri net software using realistic assumptions such as limited repair facilities, exponentially distributed failure and repair rates, and operations performed under reduced capacity. The effect of repair facility on system availability was analyzed. As the repair facility increases from 1 to 4, the system availability increases by 4% approximately. Hence, the optimum number of repair facilities for the system is 4. Further increase in the number of repair facilities (for e.g., from 4 to 5) does not contribute to availability enhancement of the system concerned.
With the rapid advancement in technology and the increasing competition among organizations and nations, the manufacturing industries are facing constant pressure related to increased productivity, reducing downtimes, and improving system availability and cost effectiveness.
