Application of Lean Manufacturing to improve productivity in the production area of the company Inversiones Generales del Mar

Abstract

The Lean Manufacturing model was applied to eliminate the series of "waste" that caused the low productivity of the company. The research had a pre-experimental design in which the productivity data for the second semester of 2016 was established as a sample. The existing problems were determined by direct observation and documentary analysis; In the same way, the necessary instruments for data collection and analysis were the Ishikawa diagram, the Value Stream Mapping software as well as different production control record sheets. The application process consisted in making a diagnosis of the cycle time of the process through the Value Stream Mapping (VSM), to later find the Takt time, then the overall efficiency of the machinery (OEE) was found. Finally, through the 5s tool and a maintenance program for the machinery, it was possible to increase productivity in the production area of the company. It was determined that the Takt time varied by 6.45%, achieving a shorter time in the manufacture of the demand of the semester 2017. With respect to the overall efficiency of machinery, this increased in 11.19% the performance of the machine. Finally, the final productivity of the workforce increased by 7.84%. For the machines, productivity improved by 8.12% and,finally, the comparison of the global productivity of the second semester of 2016 with the semester of 2017, showed an improvement of 11.08%.
