Productivity is an important parameter for all small and medium scale manufacturing industries. Lean manufacturing emerged as production strategy capable of increasing productivity by identifying and eliminating non value added activities. This article deals with productivity improvement in a pre-assembly line of gearbox manufacturing company with a case study using lean concepts like process flow chart, process Gantt chart and time study. This paper illustrates using a case study on how a value stream mapping has to be carried out in a planet carrier pre-assembly line. Value stream mapping and work standardization are the key tools used in lean manufacturing and lean transformation. It makes the process smoother, helps in reduction of lead time and ultimately increasing the productivity. From the observed results it was found that, the productivity has been increased from 7 pieces to 10 pieces in the first step assembly when the proposed VSM was implemented. The second step processing time was reduced by the execution of proposed value stream mapping with TAKT time of 126 minutes and 165 minutes of processing time for demand of 10 pieces were achieved and the overall processing time has been reduced by about 24%.

The purpose of this study is to develop a value stream mapping for a production in an aircraft manufacturing company. The process begins with creating a current state map and understands the production flow and the current cycle times. This provides the information needed to produce a future state map. The goal is to identify and eliminate the waste, which is any activity that does not add value to the final product, in the production process. In order to collect the information needed, the study was conducted within the production facility to enable the researcher gained knowledge and familiarized with the production flow and the activities being performed at the shop floor. Parameters such as cycle times, down times, work in process (WIP) for inventory and material, and information flow paths were recorded. This information will enable the researcher to visualize the current state of the process activities by mapping the material and information flow and looking for opportunities to eliminate wastes. ARENA simulation software package was used to simulate and analyze the process flow and times. Result from the analysis shows that there are areas where the company can further improve their production system. The results show the improvement of the cycle time up to 22% based on the new proposed arrangement of the layout. Therefore the propose layout will be guided to the company in order to improve their production.

This study aims to reduce the waste that occurs on each workstation and has an impact on increasing productivity and reducing production costs caused by waste that occurs during production. The data used for this study is quantitative data obtained by direct observation to the relevant departments regarding the problem of identifying waste that occurs — data taken from observations as much as 30 times the collection of data and historical data used from January 2016 to June 2017. By using the value stream mapping method on lean manufacturing, it can be seen that there are five types of waste from the existing seven waste. The five wastes are unnecessary motion, waiting, reject, transportation and in-process processes. From the results of the value stream mapping carried out a reduction in waste on each workstation with a total reduction of waste that occurs at 66.97 tons / year or 18.6% on waste gel and 88.8 tons / year or 19.3% at waste powder and there was a reduction in the changeover process for 45 minutes or 12.16% of the total changeover time before the improvement. Also, there was also an increase in the production process speed of 2 minutes 47 seconds or 4.52% from the lead time of the previous production process, 61 minutes 34 seconds to 58 minutes 47 seconds.
