Enhancement of Production in Subassembly Line of a Medium Scale Industry Using Different Lean Tools and Flexsim Simulation Software

Abstract:

In recent engineering practices, the manufacturing industries are more technically able to produce product with high quality to desire the customer needs. For accomplishing customer needs many lean tools are used to improve the methods of manufacturing practices in industries. The aim of this research work is enhance the productivity of spool casing assembly used in horn armature core per shift by using method study, time study and VSM. Cycle time for each operation of the product is determined by time study and the value added, non-value-added activities and transportation wastes occurred in the current state process identified and plotted in the current state VSM. The future state VSM was developed to reduce unnecessary wastes such as transportation, inventory, waiting which occurred in the current state VSM. Both current and future state time study are simulated using Flexsim simulation software. From the observed results it was found that, P3 and P5 model productivity was improved by about 5.5% and 6.5% respectively after implementation of appropriate lean tools.
