Facultad de Ingeniería en Sistemas, Electrónica e Industrial. Carrera de Ingeniería IndustrialThis research focused on analyzing productive planning deficiencies in the textile company "Aubea Bs". The company faces problems with demand adaptation, delivery non-compliance, and inefficient inventory management due to manual production planning methods. The objective of this research is to design an aggregate production plan to improve inventory management and optimize response capacity to market demand. The methodology included 2024 demand analysis through ABC classification, selecting the "Chompas" and "Camisetas" families (65.56% of total sales), time study to establish production standards, and evaluation of 13 forecasting models in Minitab, generating base information to develop aggregate planning strategies. The project development consisted of designing five aggregate production plans with a 12-month time horizon, using Microsoft Excel and integrating operational variables such as overtime, subcontracting, normal time production, inventory management, backorders, and personnel administration. The results demonstrate that the linear programming strategy with Solver represents the optimal alternative from an economic standpoint. This mixed strategy integrates all productive variables, generating total costs of $43.714,11 Gfor "Chompas" and $30.815,94 for "Camisetas", constituting the most efficient solution to optimize operations and improve business competitivenessItem Estandarización de los procesos productivos con enfoque en economía circular en la empresa Fabitex(2025-07) Elizalde Solis Paola Michelle; Tigre Ortega Franklin Geovanny; Universidad Técnica de Ambato. Facultad de Ingeniería en Sistemas, Electrónica e Industrial. Carrera de Ingeniería IndustrialCurrently, the textile industry faces significant challenges due to the amount of waste generated annually in the production of its goods. In this context, the present research aimed to standardize the production processes with a focus on circular economy at the company FABITEX, in order to optimize the resources used on the production line. The methodology employed was qualitative in nature with a descriptive scope, and data was collected through direct observation of the entire production department. Among the main findings, it was identified that the most in-demand product is the bedsheet, which accounts for 70% of the company’s annual sales and requires four key processes for its production: patterning, cutting, sewing, and finishing, with a standard time of 6134.69 seconds. The analysis revealed a strong reliance on empirical labor, which led to excessive textile waste being discarded without prior treatment. Therefore, circular economy principles were applied. As a result, a process manual focused on corporate sustainability was developed to reduce the identified waste. It was concluded that through the standardization of the production line, operational staff can better understand sustainable models, enhancing the company’s competitiveness in the market.Item Estudio de métodos y medición del trabajo en el área de postcosecha de la Florícola Favel Flowers Export(2025-07) Martinez Veloz Anthony Patricio; Ortiz Guerrero Daysi Margarita; Universidad Técnica de Ambato.

Carrera de Ingeniería Industrial, 2024-02) Toapanta Guangasi, Danny Javier; Ortiz Sailema, Christian IsmaelThe companies involved in the production of dog bones made from rawhide face critical challenges associated with excessive waste generation in their processes. Therefore, this research project has conducted a time and motion study in the rawhide-based canine toy production area of SOGUAR S.A. with the aim of improving production processes. The study began with the collection of information about the current situation of the company through direct observation and interviews with the general manager and production area operators. After an initial diagnosis of the company, an ABC analysis was conducted using the 2022 sales history to identify the product with the highest demand. Products with item numbers 6153 and 6910, were selected as the primary focus of the study, representing 32.45% of accumulated revenue. The production line consists of 19 processes, for which analytical flowcharts were created to provide a detailed analysis of the item's path. Time measurements were taken using the zero-return method. Subsequently, the standard time was calculated, resulting in 89.09 seconds/unit for item 6153 and 89.43 seconds/unit for item 6910. Production capacity was then calculated for each process, determining the bottleneck in the packing process. As a proposed improvement, the addition of an employee to the packing process activities is suggested. A comparative analysis for one day, one week, and one month was conducted, achieving a 50% improvement in capacity by employing two operators, thereby mitigating the bottleneck. Through the proposed methodology, 17 non-value-adding activities were identified in the packing area for both study products. Implementing the improvement proposal optimized the production process by 18.18% for item 6153 and 8.77% for item 6910. Finally, the standardization of the work method was established through work instructions.Item Planeación de requerimiento de materiales para la gestión de inventarios en la empresa Agroalimentaria Kipa Amaranto(Universidad Técnica de Ambato. Facultad de Ingeniería en Sistemas, Electrónica e Industrial. Carrera de Ingeniería Industrial, 2023-09) Sánchez Briceño, Christopher Alexander; Tubón Núñez, Edith ElenaThe main aim of the following research is the development of a material requirements planning (MRP) for Kipa Amaranto, an agro-industrial company located in Riobamba City. MRP is proposed to be implemented in order to achieve an efficient resource management. This will allow an appropriate planning of raw material acquisition and product manufacturing. Study began by gathering company information such as general data, location, and products. Through an ABC analysis, the most important products were identified. Process sheets and SIPOC diagrams were used to understand processes and relationships between suppliers, inputs, and final products. A crucial step in planning development was time study. Through the use of analytical flowcharts, different relevant processes were mapped, and methods such as Westinghouse were applied to evaluate performance and rest supplements established by the ILO to determine normal and standard times necessary for each process. In addition, an exhaustive analysis of the company's inventories and warehouses was carried out through a relevant layout design. This allowed for more efficient material management and an accurate calculation of costs associated with inventory maintenance. Likewise, historical sales data were used to make 12-month forecasts for the year 2024, which was essential in MRP implementation. A MRP for the year 2024 was developed in great detail, considering the required materials for the company’s four products. MRP application will allow for better planning of the purchases of inputs, avoiding both excess and shortage of inventory, and ensuring the timely availability of materials for production starting. Comparing current costs of $2882.45 to proposed costs of $1936.95 using the MRP, a significant savings of $945.50 was achieved. This saving represents an improvement of 32.80% in economic efficiency, highlighting the positive impact of MRP on resource management.
