    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 Ismael
    The 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.

    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 Margarita
    This 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.
