Abstract

This paper proposed an integrated product and process layout for optimizing process plant layout using a simulation approach. The proposed layout was compared to the existing layout in terms of the average work-in-process and the average waiting time of work-in-process. Currently, the plastic bag company uses process layout for its production facility layout and the activity of material movement is conducted in a batch fashion. In the proposed layout, product layout was utilized for two of six processes and process layout was utilized for the rest. Product layout changed material movement from batch into one piece flow with material handling conveyor. Software ProModel 7.0 was run in 1 year run-time with 10 replications. The simulation results show that the proposed layout reduces the average work-in-process and work-in-process waiting time in warehouse inspection by 97.92% and 96.82%, respectively. The proposed layout eliminates 47.42 minutes of the average waiting time in welding cutting temporary storage area.

Highlights

  • Facility layout refers to the way in which machines, operators, equipments, materials are positioned within a work facility

  • The results show that the proposed layout reduces the average work-in-process

  • This study presents the combination of product layout and process layout in the case of a plastic bag company

Summary

Introduction

Facility layout refers to the way in which machines, operators, equipments, materials are positioned within a work facility. It is an important element of business operations in terms of maximizing the effectiveness and the efficiency of the production process. Facility layout should be designed to minimize material handling cost between workstations. Andersen [2] stated that structuring production facilities effectively can reduce material handling costs by 10%-30%. If their departments are arranged optimally, companies can reduce product cost and increase their competitive position significantly
