Resumen
La presente investigación tiene como objetivo analizar los tiempos improductivos del servicio de mantenimiento de máquinas de soldar en los procesos (SMAW, GMAW, GTAW, PAC) de la empresa servicios y productos Joel Gutiérrez de Guayaquil. Se aplicó metodología descriptiva, deductiva, regresión lineal múltiple y diagrama de pareto.se cuantificaron perdidas que ascendieron a $40.160,00 de los cuales el 83.67% que fueron ocasionados por la falta de repuestos y mal sistema de inventario del proceso y del producto terminado. Se diseñó una propuesta aplicando la técnica ABC, inventarios, matriz BCG, cálculo de stock de máximo, mínimo punto de re-pedido y la incorporación del sistema informático esperando un aumento en la eficiencia en 19 punto porcentuales, lo que generaría TIR de 41,52%, VAN de $74.519,33 periodo de recuperación de la inversión casi en el tercer año y se evidenció la factibilidad de la propuesta.
The objective of this research is to analyze the unproductive times of the maintenance service of welding machines in the processes (SMAW, GMAW, GTAW, PAC) at the services and products company Joel Gutiérrez in Guayaquil. Descriptive, deductive methodology, multiple linear regression and Pareto diagrams were used to quantify losses that amounted to $ 40,160.00 of which 83.67% were caused by the lack of spare parts and poor inventory system of the process and the finished product. A proposal was designed applying the ABC technique, inventories, BCG matrix, calculation of maximum stock, minimum re-order point and the incorporation of the computer system expecting an increase in efficiency by 19 percentage points, which would generate IRR of 41, 52%, NPV of $ 74,519.33 period of investment recovery almost in the third year and the feasibility of the proposal was evidenced.
