Track: Modeling and Simulation

Abstract

In this paper, an earnest investigative attempt was made to provide valuable information regarding the use of Simulation modeling and Group technology. The Group technology is used to improve the part process travel distances. The simulation modeling is used to improve the overall throughput of the manufacturing cell layout. The manufacturing cell layout consists of 11 different machine cells and 12 different parts and processes with operation times. A typical part goes through the band saw machine, vertical mill, radial drill press and the NC turret mill. The machine failure times and the failure effects on the system throughput presented in this case study. The group technology ideas are presented here to improve the material handling from cell to cell using matrix manipulation techniques.  The manufacturing cell layout is modeled using discrete event simulation modeling in Arena. The parts process movements are modelled using transporter routing module in Arena. The forklift speed, loading and unloading times were modeled in this study. The improved layout minimized part routing distance with 32% improvement. The improved layout simulation model predicted 12% improvement in through put.
