Improvement of Work Processes and Methods to Achieve Production Targets Using VA/NVA Analysis, ECRS and Line Balancing

摘要

The production process is the reason why a company can survive. This is because the production process produces output in the form of products that have added value so the company can benefit from the sale of these products. In the production process there are several problems that often occurs, one of it is not achieving the production target, where the actual output produced is lower than the targeted production output. This problem will have an impact on the increase of production costs due to the implementation of overtime work. The aim of this research is to solve the problem of production target fulfillment by improving work processes and methods, such as identifying work elements which considered as waste and not adding value to the product using VA/NVA analysis; eliminate, combine, reduce and simplify work processes using the ECRS method; and minimizing production cycle time using line balancing. The results of the study show that improvements using VA/NVA analysis, ECRS and line balancing optimization using branch and bound algorithms can increase the utility of each work station, increase balance efficiency, reduce balance delay and reduce maximum cycle time or service time, thus the production targets can be achieved.
