Abstract
In automobile companies with labor-intensive processes, inefficient resource and personnel utilization leads to bottlenecks and irregular workflow, negatively impacting productivity, costs, and customer satisfaction. This is essential to minimize production losses caused by disruptions that hinder system efficiency and performance, ultimately reducing profitability. The challenges that the production line faces are low production output, significant efficiency losses, high labor costs, and irregular stoppages, among other issues. The purpose of this study is to use Arena modeling and simulation to increase efficiency and improve the performance of an automobile assembly lines. Simulation is a powerful tool for making informed decisions in complex manufacturing setups. This study specifically focuses on modeling and analyzing a vehicle assembly line at an automobile company in Iraq. It aims to help managers identify critical parameters that affect the efficiency and productivity of the production assembly line. The study evaluates the assembly line's efficiency and productivity based on three key parameters. Firstly, it examines worker utilization to determine the assembly line's relative efficiency and workforce performance. The goal is to reduce the number of workers while maintaining the same output level. Secondly, it focuses on Work in Process (WIP) to minimize the number of semi-finished products in the line, which reduces cycle time and improves throughput by introducing a buffer. The third parameter involves selecting and implementing an appropriate maintenance strategy for the assembly line. This strategy minimizes downtime and lowers maintenance costs while ensuring the line operates. This study examines how to balance the SAIPA assembly production line using Arena Simulation by modeling the existing system and then simulating and analyzing proposed improvements and future scenarios. The proposed model for the future scenario shows that the daily product output has increased by 17.85% without additional resources. At the same time, the number of workers has decreased by 45.69%. The average work-in-process has been reduced by 17.39% through facility layout restructuring and the implementation of buffer zones. This reduction in the waiting times within the system has resulted in a faster cycle during the finishing phase and quicker job transfers to other departments.
