Abstract

Object: Assembly lines are one of the essential parts of manufacturing systems that influence the overall cost and efficiency. The productivity of human resource in assembly lines directly affects the efficiency of the lines in practice.

Highlights

  • An assembly line consists of workstations connected by a conveyor belt or a similar material handling equipment.At each workstation, various operations necessary to assemble a product are performed [1]

  • Most of the studies are focused on Simple assembly Line Balancing Problem (SALBP) where the performance measure is either minimizing the number of stations or the cycle time

  • In spite of the wide research in Assembly Line Balancing Problem (ALBP), the number of papers that take into account ergonomical factors in the literature is In this study, We propose a model that aims to balance the overall physical workload for each workstation by using rapid entire body assessment (REBA)

Summary

INTRODUCTION

An assembly line consists of workstations connected by a conveyor belt or a similar material handling equipment. Most of the studies are focused on Simple assembly Line Balancing Problem (SALBP) where the performance measure is either minimizing the number of stations or the cycle time. “Monotonous body postures during repetitive jobs negatively affect assembly-line workers with the developing of Work-related Musculoskeletal Disorders (WMSDs)” [9]. These problems decrease the quality of life the workers and result in high medical expenditures for the company [10, 11]. In spite of the wide research in ALBP, the number of papers that take into account ergonomical factors in the literature is In this study, We propose a model that aims to balance the overall physical workload for each workstation by using REBA Concluding remarks and future research directions are mentioned in the last section
