Item Mejoramiento de los procesos productivos mediante un estudio de tiempos y movimientos en el área de metal mecánica de la empresa Ecuatran S.A.(Universidad Técnica de Ambato. Facultad de Ingeniería en Sistemas, Electrónica e Industrial. Carrera de Ingeniería Industrial, 2023-09) Velastegui Llanos, Christian Daniel; Ortiz Sailema, Christian IsmaelThe current research work aims to carry out a study of times and movements in order to suggest proposals to improve the production processes of the most demanded product in the metal-mechanic area of “Ecuatran S.A.” company, placed in Ambato City, which is dedicated to the manufacture and repair of electrical transformers. This research work used a qualitative-quantitative methodological approach. The qualitative approach involved direct observation, which helped to get general information about the company and the production processes. The quantitative approach was used to identify the most demanded product through an ABC analysis. In addition, the study of times and movements helped to determine the standard times and the production capacity for each process and sub-process of manufacturing the 25 kVA substation single-phase transformer. Due to the calculation of the production capacity, the bottlenecks were identified for each main process such as, lids, closing bands, and tanks through the analysis of the workload of each station and the current line balancing efficiency of each process. Subsequently, unnecessary activities were identified and eliminated to balance the workload per station only with essential activities that add value to the production processes. Because of the proposed line balancing, it was possible to obtain an improvement in balance efficiency. Regarding the forming of lids, there was an improvement of 79.06% and in terms of the forming of tanks, there was a 14.75% increase in efficiency and in productivity of 40.6% y 20.94%, respectively. With the proposed balancing of the lines and the calculation of the time required for the painting of lids, closing bands, and tanks, the established production demand could be perfectly covered. Finally, the proposal for implementing the 5'S philosophy is proposed since several problems have been observed regarding order and cleanliness. Therefore, several improvement alternatives have been developed for each phase in order to optimize the work environment and the performance of the productive flow of the company.Item Estudio de tiempos y movimientos para la optimización del proceso de producción de yogur en la empresa pasteurizadora Nutrición y vida S.A”(Universidad Técnica de Ambato. Facultad de Ingeniería en Sistemas, Electrónica e Industrial. Carrera de Ingeniería Industrial en Procesos de Automatización, 2022) Orozco Vásquez, Cristian Javier; Ortiz Sailema, Christian IsmaelThis research project arises with the need to improve the process of making yogurt, the general objective is based in realize a study of times and movements for the optimization of the production process of the product with the highest demand in the company "Pasteurizadora Nutrición y Vida S.A", the ABC methodology was used to determine the star product. The product with the highest demand in the production line is the yogurt in bottle of 4-liter Strawberry flavor, with the time study it was identified that the process that slows down the production line is lactic fermentation, which limits the company's production capacity to 99 units per day; for the movement study, the bimanual diagram was applied, which reduced a total of 11 non-efficient movements. In addition, an improvement proposal was made which deals with a plant redistribution applying the SLP method, also the number of machines needed for each area was calculated in order to increase production capacity, the FlexSim tool was used to simulate the current and proposed situation. Finally, the results of the plant redistribution show a reduction from 559.48 to 342.75 meters was obtained, decreasing 38.75% in distance traveled, also an improvement of 0.60% was obtained in process time from 1544.47 to 1535.87 minutes. 87 minutes, subsequently it was determined that one more machine is needed in the fermentation area, by simulating these results a production of 3500 units/month was obtained, comparing the current production vs. the improvement represents an increase of 1280 units which corresponds to an increase of 57.66% in production and a growth in monetary value equivalent to $3456.00.Item Estudio de tiempos y movimientos de los procesos de mantenimiento de las casetas en el taller de guías y montajes de los trenes 1 y 2 de la empresa Novacero S.A. planta Lasso(Universidad Técnica de Ambato. Facultad de Ingeniería en Sistemas, Electrónica e Industrial. Carrera de Ingeniería Industrial en Procesos de Automatización, 2022-09) Cañar Robalino, Pablo Alejandro; López Arboleda, Jessica PaolaThe following research project deals with the study of times and movements in the maintenance processes of the rolling stands in the guide and assembly workshop of production trains 1 and 2 of the company NOVACERO S.A. Lasso plant in order to standardize processes, reduce times and movements, in addition to seeking improvement situations in maintenance activities; the problem lies in the fact that the maintenance processes are not completely documented and in the non-existence of records of the execution times of the activities. This makes it difficult to plan maintenance stops for production trains, as well as reducing the chances of discovering opportunities for improvement in the work method, transfers or plant layout. Through a study of times and movements, using the Westinghouse system for the assessment of the pace of work and the allocation of supplements according to the International Labor Organization (ILO), a plant distribution is proposed for the workshop of guides and assemblies through the SLP method through which to optimize times and distances in the execution of the maintenance processes of rolling stands. The result was a 2.62% reduction in the execution time of the maintenance process and a 65.56% reduction in the total distance traveled within the workshop. Changed the distribution type from a fixed and process layout in the current distribution to a line process layout in the proposed distribution. In addition, a manual of processes and procedures aimed at standardizing the maintenance processes of rolling booths was generated with the purpose of guiding the operators in the execution of maintenance tasks.Item Estudio de tiempos y movimientos de los procesos de mantenimiento de las casetas en el taller de guías y montajes de los trenes 1 y 2 de la empresa Novacero S.A. planta Lasso(Universidad Técnica de Ambato.

Facultad de Ingeniería en Sistemas, Electrónica e Industrial. Carrera de Ingeniería Industrial en Procesos de Automatización, 2022-03) Constante Paredes, Katherine Abigail; Guachimbosa Villalba, Víctor HugoThe development of a study of times and movements in an industrial company, is an essential part for the improvement of a production line due to the possibility of standardizing processes, reducing the time in which certain activities are carried out and avoiding as much as possible the waste of time and money, this method increases the production capacity and therefore the competitiveness of the company. Therefore, the general objective of this research project is based on establishing a proposal to improve the cheese production line based on the results of the study of times and movements of the activities carried out in the elaboration of the star product, in addition through this technique standards are created, which guide an adequate planning and organization to represent an effective and efficient future. In the San José Dairy Products Company, an improvement proposal was established for the cheese production line in the elaboration of the mozzarella cheese El Cortijo 500 gr determined star product through the ABC method; through a study of times and movements, the normal and standard time was determined to carry out each of the processes, from which a plan was developed with which the company can execute the proposed improvement throughout the production line. In addition, a simulation tool was used, which represented the current situation and the proposal once the opportunities for improvement were analyzed and established.
