    Plan de mantenimiento aplicando la metodología (RCM) para el área de producción de Cepolfi Industrial C.A.

    The main objective of this research was to propose a maintenance plan applying the RCM methodology for the production area of the company Cepolfi Industrial C.A. An analysis and coding of the equipment and machinery in the production area of the company was carried out, which was made up of 3 digits, the first corresponding to the production plant, the second digit to the area where the equipment is located, and the third digit belonged to the initials and numbering of each of the machines, following the guidelines of the ISO 14224 standard. Subsequently, failure modes and effects matrices (FMEA) were made, in which the components of each machinery and equipment are broken down, with the respective failures that occur, after which the IRP (Risk Priority Index) was calculated by multiplying the severity index (G), by the occurrence index (O) and the detectability (D), which according to NTP 679, if the value is greater than 100 the risk is considered high. Similarly, the decision matrices of each machinery of the Cepolfi company were created based on the weighted factor method, considering 5 factors, the priority for the operation of the machine (P), the implementation cost (C), the technical feasibility (F), the scope (A), and the available resources (R), each of these factors were scored as 1 = Low, 2 = Medium Low, 3 = Medium, 4 = Medium High and 5 = High, this helped in the selection of the most relevant maintenance tasks for each equipment and machinery. With the previously developed procedures, the predictive maintenance plan based on RCM was developed, focused on the identification of key components, fault prioritization, definition of specific protocols, selection of tasks based on decision matrices. Finally, the maintenance schedule was included with a one-year projection, using color scales with their respective frequency of performance, which becomes a tool to organize, plan and optimize the management of predictive maintenance, with the purpose of increasing production, preventing unforeseen stoppages.

    Plan de mantenimiento preventivo para la cadena de frío de la empresa Skandinar S.A.
    (Universidad Técnica de Ambato. Facultad de Ingeniería en Sistemas, Electrónica e Industrial. Carrera de Ingeniería Industrial, 2024-08) Masache Lisintuña, Carlos Alejandro; Urrutia Urrutia, Fernando
    The present research project aims to develop a preventive maintenance plan for the cold chain of SKANDINAR S.A. This will enable the preservation and maintenance of equipment in optimal conditions by identifying failures and critical components. The purpose is to avoid unscheduled downtime and ensure the continuous development of daily activities within the company. Based on the analysis of cold chain equipment operation, maintenance indicators were calculated, including reliability, availability, and maintainability. To prioritize components prone to failures, the Failure Mode and Effects Analysis (FMEA) matrix certified by NTP 679 was utilized, evaluating each component according to detectability, severity, and frequency, and determining its criticality through the risk priority index. The proposed maintenance plan includes the development of maintenance schedules based on the criticality of each component, designed to enhance reliability, availability, and maintainability. These schedules enable the generation of work orders, detailing the planning and scheduling of activities aimed at preventive maintenance. To increase the effectiveness of the plan, the implementation of maintenance software is proposed, facilitating the scheduling, adjustment, and modification of the maintenance plan according to the company's needs.

    Desarrollo del sistema de gestión de mantenimiento para maquinarias Caterpillar en la inmobiliaria freire oriental Cia. Ltda.
    (Universidad Técnica de Ambato. Facultad de Ingeniería en Sistemas, Electrónica e Industrial. Carrera de Ingeniería Industrial en Procesos de Automatización, 2024-05) Torres Tipán, Edison Xavier; Ortiz Sailema, Christian Ismael
    The objective of this project is to establish a set of procedures to standardize the maintenance activities for Caterpillar machinery at Inmobiliaria Freire Oriental CIA. LTDA. The project analyzes the processes involved in both preventive and corrective maintenance of the machines. The recommended service hours for maintenance provided by Caterpillar were identified. A maintenance schedule was established to organize and prioritize maintenance activities according to their importance and urgency. A manual was created specifying the actions to be performed in each maintenance procedure, such as changing, performing, lubricating, and inspecting. The aim is to ensure that the excavators operate optimally and to prevent failures or issues that could cause production stoppages and economic losses. Additionally, the project promotes the incorporation of new work methods and the optimization of raw material resources. Preventive and corrective maintenance plans are implemented to keep the machinery in optimal condition and to minimize the impact on operational continuity.
