ABSTRACT

The present work was elaborated with the purpose of implementing an improvement plan to reduce the operating costs of a manufacturing company, which is dedicated to the manufacture of masks, aprons, banners and religious mantles;It should be noted that during the period of time in which the investigation is carried out, the company only manufactures masks and aprons, due to the pandemic caused by COVID-19. Through an observation guide and historical data, it is possible to obtain a comprehensive diagnosis composed of SWOT analysis, EFE matrix, EFI matrix, PESTEL and DOP analysis;thus allowing to find different problems such as a high percentage of waste, poor quality control, poor quality raw material, a constant rotation of suppliers and overstock. Improvement plan 1 made up of TPM, efficient selection of suppliers, MRP and TQM is chosen. The improvement plan was simulated using the ProModel and Ms. Excel software using the supply planning simulator (Odoo). After applying the improvement plan for each indicator, a total benefit of S/.2324.49 is reached, that is, the operating costs of the manufacturing company decrease by 25.32%. Also, a NPV of 351.1 soles, an NPV of Income of 19, 741.00 soles, an NPV of Expenditures of 19, 390.00 soles, an internal rate of return of 3%, a TMAR of 1.53%, which ratifies the viability of the project by the prompt return on investment, with a B/C of 1.02. © 2022 Latin American and Caribbean Consortium of Engineering Institutions.
