    This project focuses on the analysis of time and motion in the production processes of the standard line for Pre-Delivery Inspection (PDI) at CIAUTO Cía. Ltda., an Ecuadorian company that leads in the manufacturing of Great Wall Motors vehicles. In response to delays caused by non-value-added tasks, poor communication, and inadequate resource distribution, the objective is to optimize operational efficiency through method engineering tools. The methodology employed includes time measurement, flowchart analysis, and statistical techniques, allowing for the calculation of standard times and the identification of bottlenecks in the reception, washing, standard work, and inspection lines. Additionally, a detailed diagnosis of current activities was conducted, identifying unproductive times and proposing improvements. Solutions include the reconfiguration of workstations and the standardization of processes through detailed work instructions. The results demonstrate a significant reduction in cycle times and an increase in productivity: 4.9% in reception, 6.7% in washing, and 9.4% in motor compartment tasks. These improvements not only enhance operational efficiency but also strengthen CIAUTO's competitive capacity in a growing automotive market. The comprehensive proposal ensures alignment with international standards, contributes to organizational sustainability, and promotes a continuous workflow, establishing CIAUTO as a benchmark in the Ecuadorian automotive industry.

    Estudio del trabajo en los procesos productivos de la empresa de fabricación de suelas “Multinyec”
    (Universidad Técnica de Ambato. Facultad de Ingeniería en Sistemas, Electrónica e Industrial. Carrera de Ingeniería Industrial, 2024-08) López López, Jessica Liliana; Ortiz Guerrero, Daysi Margarita
    This thesis investigates the work processes within the production operations of "MULTINYEC," a company specializing in sole manufacturing. The research emphasizes the necessity of examining work activities to enhance operational efficiency, reduce manufacturing times, and increase overall productivity. Through a meticulous analysis of critical operations in areas such as milling, injection molding, and packaging, unnecessary activities were identified and eliminated, and time standards to produce sports soles were established. The study employed a comprehensive approach to gather detailed and accurate information, utilizing various data collection techniques. These included direct observation within the company’s facilities, informal interviews with production staff, and an immersive investigation into the workplace environment. Additionally, the research involved a thorough review of documents related to work methods and time-motion studies, coupled with interviews to collect both qualitative and quantitative data. The documentation of activities in each process area was achieved with flowcharts, synoptic and analytical cursograms, man-machine diagrams, and the application of the SMED (Single-Minute Exchange of Die) methodology. The current production methods were rigorously analyzed through the technique of detailed questioning, leading to the identification of potential improvements by eliminating, combining, or simplifying operations. As a result of these efforts, the study demonstrated a notable enhancement in the company's productivity, with a 6.24% increase compared to the existing production methods. This thesis not only provides a detailed examination of the work processes at MULTINYEC but also presents actionable insights and recommendations for further efficiency improvements.
