Mejora del proceso productivo en la Empresa Balanceados Nutritivos de la ciudad de Riobamba aplicando las herramientas Lean Manufacturing

Abstract

The technical project was carried out in Balanceados Nutritivos Company, located in Riobamba city, the main objective was to improve the company's production by implementing Lean Manufacturing tools. To develop the research, an integral analysis of the original situation of the company was conducted by means of a VSM diagram. In addition, historical production data were reviewed, the information was analyzed in the process diagram and flowchart, supplemented with the use of 5'S tools. A cycle time of 21.61 minutes was measured for the processing of two tons, with a production of 5.54 tons per hour. During the process enhancement analysis, opportunities were identified applying Kaizen bursts. The time taken in the mixing process, which generated bottlenecks and delays due to the water dosing system employed, was especially highlighted. One of the most important improvements was the change of the liquid dosing system, together with the standardization of the process. These actions contributed to a standard cycle time of 19.40 minutes, increasing production to 6.2 tons per hour. As a result, daily production was improved, resulting in an increase of 116 units per day. Taking into consideration the retail price of $25.35 and the profit margin of 5%, a net profit of $1.27 per unit was generated, which was shown as a gross profit of $147.32 per day. The efficiency of the liquid injection times by the introduction of the new dosing system led to a substantial increase in productivity, coupled with the implementation of the 5'S practices, performed a crucial role in reducing waste and resulting in much more efficient operations.
