Abstract

In order to satisfy the rising demand for components, production line efficiency is crucial in aircraft manufacturing. Traditional manual analysis approaches are limited in their ability to capture the complex relationships that exist throughout production processes. However, simulation modelling appears to be a potential strategy for increasing efficiency. Using Witness simulation models, this study tries to improve production line efficiency in an aircraft manufacturing industry. The study's goal is to comprehend present processes, uncover inefficiencies, and investigate improvement solutions. Experiments based on simulation will be used to assess the impact of suggested modifications on key performance measures. The problem statement highlights the difficulties that aerospace manufacturing companies have in obtaining optimum efficiency, which leads to increasing costs and production delays. Productivity enhancement is hampered by a lack of full understanding of existing processes. The study goals include creating a simulation model, conducting a line balance analysis, and recommending changes. The scope of the study is limited to a single production line, with modelling and analysis performed using Witness Horizon software. However, the supply chain is not addressed. The findings will assist aerospace firms in identifying bottlenecks and implementing data-driven methods to improve production line efficiency.
