Statistical Analysis in Assembly Line Balancing: Lean Manufacturing Application in Energy Sector

Abstract

The elimination of non-value added activities, maximizing the use of resources, reducing costs, ensuring continuity of these eforts, increasing quality and productivity are essential forms. The lean manufacturing technique developed for this purpose is based on statistics data. Statistical analysis provides an improvement by presenting the current situation and future situation. The lean manufacturing operation was carried out in the "Qatar Breaker" assembly line, which operates in the energy sector. Circuit breakers are switchgears which are used to cut o the load current and short-circuit currents occur in high voltage and high-current switches. In this study, The Lean Production Activity Plan is conducted. Throughout this plan, process data collection, process analysis, process uctuation and then standardization with kaizen have been applied in this order. Due to the fact that the use of automation is not widespread in the production system of the factory and manual labor is of rst priority, process analyses were made with video records. Then standard operation tables were prepared and new process design was created according to the combination of these tables and sales planning departments' data. As a result, assembly line balancing was performed by creating work ow according to this new process design.
