Gestión de mantenimiento mediante Lean Maintenance para Bioalimentar Cía. Ltda.
(Universidad Técnica de Ambato. Facultad de Ingeniería en Sistemas, Electrónica e Industrial. Carrera de Ingeniería Industrial en Procesos de Automatización, 2023-03) Almachi Guanoluisa, Evelin Jesenia; Tigre Ortega, Franklin Geovanny
The objective of this project is to improve maintenance management at Bioalimentar Cía. Ltda. through the application of Lean Maintenance tools. To achieve this objective, 3 investigative stages were carried out. The first stage includes the analysis of the initial situation through a diagnosis in which 12 maintenance management axes are considered through the application of the evaluation of the COVENIN 2500-93 manual, determining the areas of strength and management deficiency. In addition, observations, interviews and data collection are used as tools that facilitate the identification of conflicting activities. In the second stage, the selection of tools is carried out through the hierarchical analytical process to provide qualitative-quantitative support to the investigation and improve the priority aspects to be addressed in the maintenance management of Bioalimentar. With the calculation of the priorities, the development of 3 Lean Maintenance tools is determined, which are: 5S, Standardization and Poka Yoke; and, the third stage documentally develops each of the selected tools proposing processes, formats and flow charts that continuously describe how to implement and record data for its implementation, monitoring and control. Finally, this research project concludes that once the selected Lean Maintenance tools are adapted to improve maintenance management in Bioalimentar, it would be expected to achieve a decrease in spare parts waits and loss of time due to rework in maintenance activities that it will favor the effective fulfillment of the weekly work schedule.
Herramientas de manufactura esbelta para la mejora continua de los procesos en un restaurante de comida rápida
(Universidad Técnica de Ambato. Facultad de Ingeniería en Sistemas, Electrónica e Industrial. Carrera de Ingeniería Industrial en Procesos de Automatización, 2023-09) Chacón Tello, Carlos Patricio; Tigre Ortega, Franklin Geovanny
The present research work was carried out in the fast-food restaurant "Broos Burguer Las Chancros de la 13" located on Joaquín Aillón and Lizardo Ruiz streets, a company dedicated to providing fast food service, with the aim of applying tools Lean manufacturing for the continuous improvement of processes in a restaurant. With an initial analysis, the main changes within the process were identified, in order to provide a solution to the problems encountered, the management of a reference implementation proposal for lean manufacturing tools and continuous improvement methodologies in restaurant processes is proposed. . For this research, improvement proposals were developed opting for a first 5S methodology, implemented in the production areas, to reduce the necessary elements in all areas, which will benefit the flow of the material, reducing the number of elements out of their place the creation and definition of new spaces for the storage of utensils and the application of a cleaning manual, the time spent cleaning each area is reduced based on defining specific procedures and activities for this activity in each area; The second methodology is based on a redistribution of the plant to reduce the movements or transfers of personnel, obtaining a reduction from 676,87 m to 467,34 m, that is, 209,52 meters per day, obtaining an improvement of 30,97% in the reduction of movements. or transfers of personnel, with the new arrangement of elements, redirection of the material flow and reduction of the response time of the employees to deliver the order, through the simulation of the process in the FlexSim 2019 program
Mejora de la productividad en la línea de producción de tela kiana de la empresa textil “M&B” aplicando tiempos y movimientos
(Universidad Técnica de Ambato. Facultad de Ingeniería en Sistemas, Electrónica e Industrial. Carrera de Ingeniería Industrial en Procesos de Automatización, 2023-03) Rodríguez Panata, Sara Rebeca; Ortiz Sailema, Christian Ismael
The production processes related to the manufacture of fabrics are closely linked to the use of machinery, labor, resources and inputs to produce the final product. However, the empirical way in which Textiles M&B has grown, has caused that there is no standard time of operations and much less documented procedures for operators to know how to perform their activities, causing unnecessary waiting, transportation and movements in the production line of Kiana fabric. The purpose of this research is to improve the productivity levels of Kiana fabric. The study includes the analysis of the stages of the production process, with respect to the evaluation of the work rhythm through the Westinghouse system, the assignment of supplements according to the criteria of the International Labor Organization, t he measurement or timing of the activities, to determine the standard time of the processes and based on that to apply improvements that allow to increase the production of Kiana fabric based on the elimination of unnecessary movements, transports and wait s in the production process. The results show that by applying the 5S and SMED methodologies, the production process is improved by 3.04%. The new work methods are embodied in a procedures manual to standardize operations. Finally, it is concluded that productivity levels increase by 44.62% with the proposals established to improve the production process.
Mejora de productividad basada en herramientas de Lean Manufacturing, para los procesos productivos de la empresa Curtiduría La PENÍNSULA
(Universidad Técnica de Ambato. Facultad de Ingeniería en Sistemas, Electrónica e Industrial. Carrera de Ingeniería Industrial en Procesos de Automatización, 2023-03) Ojeda Altamirano, Diego Fabián; Tigre Ortega, Franklin Geovanny
This research work was carried out in the tannery "La Península", a company dedicated to the production of leather for footwear and clothing, with the aim of solving problems present in their production processes. Under an exhaustive initial analysis, several problems were identified, defining the most frequent and main ones in order to solve them and alleviate the critical areas of the process. A proposal was made to implement continuous improvement methodologies in the company in order to increase the company's productivity levels. For this investigation, improvement proposals were executed where the 5S methodology was implemented in all production areas, removing or transferring unnecessary elements from each area, thus recovering 22.9 m^2, reducing 4.71% of the time spent searching for tools, in addition, cleaning procedures were defined, cutting 25.78 minutes of cleaning time per week. With regard to the application of the SMED tool, the changeover time on the router was reduced from 10:25 minutes to 6:47 minutes and on the press machine it was reduced from 10:41 minutes to 7:47 minutes. After applying the two methodologies, an improvement in the leather manufacturing processes is observed, fulfilling the objective of increasing productivity levels.
