Resumen
El objetivo de esta tesis es implementar técnicas de ingeniería
industrial para analizar y mejorar el proceso de producción de cemento;
mediante la técnica de Teoría de las Restricciones se identifico las fallas
del proceso. Holcim planta Guayaquil se dedica a la fabricación de
cemento para lo cual extrae su materia prima (caliza y arenisca) y la
procesa juntos con otros aditivos necesarios para la producción de
cemento y este se lo distribuye mediante su franquiciado “Disensa”. En el
proceso de producción de cemento se ah podido identificar varios puntos
importantes que generan pérdidas causadas por: a) Sobre-Alimentación
del elevador, b) Baja calidad de los blindajes de los molinos de bolas, c)
Falta de un sistema apropiado de inventarios de productos; se ha
contabilizado como pérdida $446.600. Entre las mejoras planteadas
tenemos: El uso de los Ensayos No Destructivos para el problema (a) y
(b) debido a su semejanzas y para el literal (c) la implementación de un
programa que permita la adquisición de bienes y/o servicios y así facilitar
la gestión del departamento de suministros. El beneficio/costo es de $4
dólares por la implementación de los Ensayos No Destructivos para el
problema de Sobre-Alimentación del elevador; $1 dólar por la utilización
de los Ensayos No Destructivos debido a la baja calidad de los blindajes
de los molinos de bolas; $2 dólares por la creación de un programa para
trabajar en conjunto por parte del departamento de suministros con los
proveedores. Los costos de esta inversión son de $116.800 dólares lo que
representan una mínima inversión comparado con $ 446.600 dólares que
sería lo que se beneficiaria la empresa.
The objective of this thesis is to implement engineering techniques Industrial to analyze and improve the production process of cement; using the technique of Theory of Constraints faults are identified process. Guayaquil Holcim plant is dedicated to manufacturing cement which draws its raw materials (limestone and sandstone) and processes together with other additives necessary for the production of cement and this is what distributes through its franchisee "Disensa". In the cement production process is able to identify several points ah generating significant losses caused by: a) On-Food elevator, b) Low quality of the shielding of ball mills, c) Lack of an appropriate system of product inventories; has loss recorded as $ 446,600. Among the improvements raised we have: Using Non-Destructive Testing for the problem (a) and (B) due to their similarities and to paragraph (c) implementation of a program to purchase goods and / or services and facilitate management department supplies. The benefit / cost is $ 4 dollars for the implementation of NDT for Over-supply problem of the elevator; $ 1 for the use of NDT because of the low quality of the shielding of ball mills; $ 2 for the creation of a program to work together by the supply department with suppliers. The costs of this investment are $ $ 116,800 which represent a minimal investment compared to $ $ 446 600 to would be that the company would benefit.
