Optimización del proceso productivo a través de técnicas de ingeniería de métodos y control de inventarios en la empresa Inoxidables élite ubicada en la Ciudad de Riobamba

Abstract

Inoxidables Élite is a manufacturing company in the metalworking sector, specializing in the production of industrial equipment for the agro-industry. Although its infrastructure and machinery allow semi-automated processes, the company still uses a traditional and empirical production methodology, which generates disadvantages in the management and control of processes. To enhance efficiency and productivity, engineering methods and inventory control techniques were implemented. An ABC analysis of 2023 sales identified seven production lines, with the cold line representing 50% of total production. Within this line, horizontal refrigerators accounted for 49% of sales, being in high demand and of significant economic value. Based on this data, a historical demand analysis for refrigerators was conducted, forecasting the production of 53 units for 2024, averaging four units per month. Additionally, a safety stock was established to ensure efficient material supply during production. Following improvements in plant layout, the 5S methodology, production process analysis, and inventory control tools, the production cycle time for refrigerators was reduced from 13 to 11 working days. The process path was decreased from 445 meters to 283.5 meters, significantly reducing it by 164.5 meters. In terms of production costs, a reduction from $1,393.39 to $1,263.51 was achieved, saving $129.88. These improvements increased the productivity of the refrigerator manufacturing process, raising it from 78% to 84%.
