Item Diseño de la metodología Lean Logistics para la gestión eficiente del proceso de despacho en la distribuidora Dismar(Universidad Técnica de Ambato. Facultad de Ingeniería en Sistemas, Electrónica e Industrial. Carrera de Ingeniería Industrial, 2024-08) Mayorga Zapata, Adrián Gustavo; Naranjo Chiriboga, Israel ErnestoDispatch process management at Distribuidora DISMAR faces significant challenges that impact operational efficiency and customer satisfaction. The central problem lies in the existence of activities that do not add value to the final customer, as well as the presence of waste such as waiting times, unnecessary movements, and defects in the process. Therefore, this project objective is to design a Lean Logistics based methodology to tackle these challenges and improve the dispatch process management at DISMAR. To achieve this objective, a methodology that included identifying non-value-adding activities, designing Lean tools such as Value Stream Mapping (VSM), Kaizen, and JIDOKA was employed, as well as evaluating and selecting specific solutions to enhance the dispatch process. Main results show a significant improvement in process efficiency, with reductions in waiting times, unnecessary movements, and defects. Additionally, specific solutions were implemented, such as warehouse layout redistribution, automated billing software introduction, proper warehouse signage, and the use of barcode reading equipment to avoid defects during product selection. These solutions proved effectiveness in optimizing the dispatch process. Regarding transportation, the initial monthly cost was reduced by 58.88%, from $1,627.13 to $669.19; the initial monthly waiting cost was reduced by 51.46%, from $250.23 to $128.77 and the time spent was reduced by 51.48% compared to the initial situation. Additionally, estimated annual savings from implementing the proposed solutions is $13,040.52, which justifies cost of proposals amounting to $1,200.40. These results highlight the effectiveness of Lean Logistics methodology as a solid foundation for optimizing processes and achieving more efficient management at DISMAR.Item Metodología lean manufacturing en los procesos productivos de la empresa Confecciones Deportivas Piscis(Universidad Técnica de Ambato. Facultad de Ingeniería en Sistemas, Electrónica e Industrial. Carrera de Ingeniería Industrial, 2024-02) Santiana Navarrete, Kevin Stalin; Ortiz Guerrero, Daysi MargaritaThis research project focuses on developing Lean Manufacturing methodology in production processes at Confecciones Deportivas PISCIS company, proposing solutions based on specific tools and methodologies to optimize production. The most profitable product was identified from a survey of information, using analytical cursograms to describe activities, in the time study the General Electric method was applied and the timing back to zero for characterizing the current situation through the creation of the value chain map (VSM), identifying critical areas and opportunities for improvement. Through direct observation analysis, critical wastes were defined as defects, overproduction, and waiting times. Their causes were quantified to establish opportunities for improvement and through a bibliographic review allowed the selection of optimal tools such as JIDOKA, KAIZEN, TPM, and 5'S. These tools application generated corrective actions to eradicate production defects, an increase in OEE to 63.31%, and with the 5'S methodology a standardized work method was achieved, improving product quality and customer satisfaction. This systematic approach seeks to increase efficiency and competitiveness in the textile sector.Item Análisis de los niveles de desperdicio desde la perspectiva de lean manufacturing en la empresa Renova(Universidad Técnica de Ambato. Facultad de Ingeniería en Sistemas, Electrónica e Industrial. Carrera de Ingeniería Industrial, 2023-03) Freire Guevara, Jonathan Santiago; Naranjo Chiriboga, Israel ErnestoThis research project is based on classic Lean Manufacturing wastes analysis that are present in production processes at RENOVA Company and is focused on proposing an action plan through Lean Manufacturing philosophy tools and methodologies application contemplated in a manual that allows the resources optimization, achieving a better productive flow and greater efficiency in the products delivery to final customer. From sales history between January and October of 2022 and through an ABC analysis the most profitable product was known, on which the information gathering of existing processes was carried out and later a time study was developed for the current VSM trace that allowed to determine initial production plant situation, where the present wastes were known as: defects of which 44% were associated to the machine factor and 56% to the human factor; reprocesses with a higher incidence of stitch jumps with 23.44% compared to the other causes; unnecessary movements by the warehouse and docking operator adding a total of 52.53% of unproductive time; waits mostly in the warehouse for finished product with 67.25% and inventory where a total of 240 garments were detected in season at the end of November. Through a cause analysis, improvement opportunities were established for each identified waste, which were complemented by a literature review of the advantages and contributions of each tool for its subsequent selection, resulting in the following methodologies: JIDOKA, TPM, APU and HEIJUNKA. By tools applying, a reduction in defects per unit percentage is established, an increase in the overall efficiency index of the equipment of 40.94%, a reduction of displaced meters of 72.86%, and finally, the elimination of waits and inventories by producing what is necessary in required time which brings an improvement of 77.27% in product delivery days to the final customer.Item Modelo de implementación del sistema de manufactura esbelta para la optimización de los procesos de producción textil(Universidad Técnica de Ambato. Facultad de Ingeniería en Sistemas, Electrónica e Industrial. Maestría en Gestión de Operaciones, 2018) Ortiz Guerrero, Daysi Margarita; Sánchez Rosero, Carlos HumbertoEl presente proyecto de investigación está enfocado en desarrollar un modelo de implementación del sistema de manufactura esbelta en la empresa Texmareli con el fin de optimizar los procesos operativos de producción textil. A través de la recolección de la información obtenida mediante el mapa de procesos, el diagrama de flujo de procesos, el estudio de tiempos, la representación gráfica del layout y los datos históricos se identificó el estado actual de la línea de producción y mediante el mapa de la cadena de valor se determinaron los desperdicios, es decir lo que no agrega valor al producto final. Con los desperdicios identificados y mediante el análisis de las herramientas de manufactura esbelta se seleccionó las técnicas apropiadas que generen cambios sustanciales en el manejo de los procesos de confección textil, y de esta forma reducir los tiempos de ciclo mediante la eliminación de las esperas, transportes, movimientos innecesarios y reprocesos. Se propuso un sistema de producción esbelta, basado en la reducción de la línea de producción a través del rediseño de layout, eliminación de los movimientos incensarios mediante la aplicación de las 5 S´s, reducción de los tiempos de cambio de máquina mediante la aplicación del SMED, reducción del inventario en proceso mediante el balanceo de línea y la eliminación de los productos defectuosos mediante un control autónomo jidoka por los operadores. En base a la propuesta planteada, se reducirá los tiempos de ciclo, el lead time del proceso, inventario en proceso y movimientos innecesarios y por ende se incrementará la capacidad de producción para satisfacer la demanda de los clientes.
