Planeación de requerimiento de materiales para la gestión de inventarios en la empresa Agroalimentaria Kipa Amaranto

Abstract

The 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.
