Abstract

This paper work presents a model of implementation of lean manufacturing for improving productivity and quality, by conducting a case study in a small scale industry at Ranchi, Jharkhand. The purposes of this paper are to identify waste related problems, cause of equipment failure, bottleneck problems and rectify them. The above problems are analyzed in concern with rejection control, inventory control, waiting time, set time and eliminating non value added time / activities. The complete problem is identified and depicted by value stream mapping. This paper conclude with discussing improvements and it proposes Value stream mapping lean tools can be applied in small scale industries and calculation of takt time for reduction of wastage and increasing productivity.

6. Conclusion

In the above mentioned case study, work has been done on identifying the waste related areas as a study of lean manufacturing. It has been found that the reason for non-value added activities are due to wrong handling material, long distance, defect and improper inventory. After literature study in the field of lean tools we concluded that the VSM is an effective tool for eliminating these wastes and study also suggested the ways to reduce non value added times in a manufacturing process. Large reductions in time consumption can be achieved by reducing the waiting time of a job during production process. Most important point is that in this improvement process, no new machines were purchased nor were operators expected to work faster or harder; only procedures and layouts were changed to allow the product to flow more smoothly through the manufacturing process. And this activity reduced the manufacturing lead time intern increased the productivity of a small scale industry.
