Improvement of production system efficiency and production capacity using line balancing method

Abstract

This study discusses the research results conducted on an Indonesian plastic manufacturing company. The distribution of the workload in a production process needs to be calculated so that the company is able to achieve the target of production. This research was conducted to improve the efficiency of production systems and the production capacity of the company so that the company is able to meet production targets. The method used in this study is line balancing. Time study method is conducted to calculate cycle time and then forecasting method is utilized to determine production target and required cycle time. After that, 3 methods of line balancing: ranked positional weights, Moodie Young and new bidirectional is used. The result of the line balancing method shows that the best methods are Moodie Young and new bidirectional with the efficiency of 82.97%, much higher from the current state, which is only 48.89%. The number of workstation is also decreased from 9 to 7. The production also increased from 780.41 pieces per day to 1,030.07 pieces per day.
