Estudio de tiempos y métodos para la optimización de los procesos productivos y la gestión de inventario en la empresa de suelas de zapatillas “BRPLAST”.

Abstract

The present study focuses on optimising production processes and inventory management at BRPlast, a company dedicated to manufacturing ultraboost sports soles made from expanded PVC and TPU. The central problem identified is the lack of process optimisation and poor coordination between areas, which affects the operational efficiency and competitiveness of the company. The project's objective is to diagnose the current situation, identify bottlenecks, and propose improvements to reduce production times. The methodology used combines direct observation, interviews, and document analysis, supported by tools such as Microsoft Word, Excel, Visio, and AutoCAD, along with real-time data capture devices. Multifactor productivity is evaluated, and industrial process characterisation matrices are used to identify areas for improvement. The results highlight the efficient structure of the production lines, with semi-automatic processes that minimise delays and an ergonomic layout that avoids bottlenecks. The inventory analysis reveals that single-colour expanded PVC soles are the best-selling product, classified as class A in the ABC inventory control method. Differentiated reorder points are established to ensure the timely availability of raw materials. Finally, the importance of continuing to improve operational efficiency and strategic inventory management is highlighted to maintain and strengthen BRPlast's competitiveness in the sports soles market.
