Resumen
El objetivo de la presente tesis de grado es: Mejorar la productividad
de la línea de enrollados de la empresa SUPAN, mediante la aplicación de
la teoría de restricciones (TOC). Para diagnosticar la situación actual de la
empresa, se ha analizado los diversos procesos productivos del área
donde se elaboran panes enrollados, para lo cual se han utilizando
diagramas de operaciones, de bloque, de planta, de recorrido y
herramientas de diagnóstico, como diagramas de Ishikawa y de Pareto,
con los cuales se detectó los principales problemas que afectan a esta
sección de la empresa, que conciernen a los daños en la cámara de
fermentación y las demoras en la operación de enfundado, que generan un
bajo nivel de eficiencia, debido a la obsolescencia de los rodamientos
horizontales y verticales, así como por la falta de tecnología adecuada
para el proceso de enfundado de los artículos terminados, cuyo efecto son
los tiempos improductivos, reproceso y desperdicio, lo que ha traído como
consecuencia pérdidas anuales por la cantidad de $102.644,00. La
propuesta para enfrentar los problemas se refiere a la aplicación de la
Teoría de Restricciones (TOC), escogiendo la alternativa de solución de
reemplazar 3.996 rodamientos obsoletos por rodamientos horizontales y
verticales nuevos, para evitar paralizaciones en la cámara de
fermentación, además de la adquisición de una máquina enfundadora para
realizar el proceso de enfundado de pan enrollado, para evitar paros no
programados en la planta de producción, donde se elaboran dichos
artículos, con lo cual se determina el incremento de la eficiencia de
75,29% a 94,94%, es decir, 19,65% de incremento, evidenciando con ello
la factibilidad técnica. La inversión total para el reemplazo de los
rodamientos obsoleto y la compra de la máquina enfundadora asciende a
la cantidad de $166.096,64, de los cuales la inversión fija corresponde al
92,34% ($153.372,42) y los costos de operación el 7,66% ($12.724,22),
que será recuperado en 1 año y 7 meses, generando una Tasa Interna de
Retorno (TIR) de 54,77% y un Valor Actual Neto (VAN) de $280.639,12, lo
que demuestra la factibilidad técnica – económica.
The objective of this thesis is: Improving productivity coiled line SUPAN company, by applying theory of constraints (TOC). To diagnose the current situation company, we have analyzed the various production processes of the area where coils are produced breads, for which were used flowcharts, block, plant, stroke and diagnostic tools such as Ishikawa diagrams and Pareto with which the major problems affecting this was detected section of the company concerning the damage to the camera Fermentation and delays in operation sleeving, which generate a low efficiency, due to the obsolescence of the bearings horizontal and vertical, as well as the lack of appropriate technology for sleeving process finished goods, which effect are downtime, rework and waste, which has brought annual losses result in the amount of $ 102,644.00. The proposed to address the problems concerning the implementation of the Theory of Constraints (TOC), choosing the alternative solution 3,996 to replace obsolete bearings and bearings for horizontal new vertical to avoid stoppages at camera in addition to the acquisition of a fermentation sleever make the process of sleeving wrapped bread to avoid stoppages programmed in the production plant, where they are produced these articles, thereby increasing the efficiency of determining 75.29% to 94.94%, that is, 19.65% increase, thereby evidencing technical feasibility. The total investment for the replacement of obsolete bearings and purchase amounts to the stretch hood machine the amount of $ 166,096.64, which corresponds to fixed investment 92.34% ($ 153,372.42) and operating costs 7.66% ($ 12,724.22), to be recovered at 1 year and 7 months, generating an internal rate of Return (IRR) of 54.77% and Net Present Value (NPV) of $ 280,639.12, which demonstrating the technical feasibility - financial.
