El presente trabajo de investigación tuvo por objetivo desarrollar un modelo de gestión basado en Lean Six Sigma para incrementar la productividad en la industria alimentaria, tomando como caso de estudio una fábrica de néctares de Lima, Perú. La metodología utilizada fue cuantitativa, de tipo aplicativa y diseño preexperimental de corte transversal. Se empleó la observación como técnica principal de recolección de datos y fichas de registro de datos como instrumentos. La población estuvo conformada por 616 ciclos de acondicionado; mientras que, la muestra, por 60 ciclos elegidos a través de criterio del investigador. Los resultados evidenciaron mejoras significativas tras la implementación del modelo. La eficiencia aumentó en un 3.58%, lo que permitió un mayor aprovechamiento de la fruta en cada ciclo de acondicionado. Además, la variabilidad se redujo en un 26.66%, alc...

In Peru, the textile industry represents a very important sector due to its significant contribution to the national GDP. All 398 thousand workers in this sector are prone to suffer from musculoskeletal disorders (MSDs), since the operation of machinery and handling of materials involves prolonged repetitive movements, causing strain on the body. This research aims to reduce the risk level of MSDs in a garment manufacturing SME. Therefore, an ergonomic method was developed based on REBA and RULA integration, which also proposes preventive and corrective measures. A initial evaluation was performed based on the observed postures of the operators to identify the risk levels; subsequently, the evaluation was repeated upon the implementation of the method in order to estimate its effectiveness. As a result, there was an improvement of 44.97%, that is, the level of risk to which the workers a...

The textile and apparel sector is one of the most relevant and representative in Peru, due to its tradition and its contribution to the national economy. In recent years, however, it has had to become more competitive, largely due to the entry of international textile product suppliers into the local market. Therefore, companies that comprise this sector must adopt tools that will allow them to increase their productivity. In view of this situation, this research aimed to develop and implement an application model using Value Stream Mapping (VSM) in a textile and apparel company that manufactures garments for export, demonstrating at the same time that VSM is the best tool to visualize the entire supply chain in a single document. It also makes it possible to identify areas of opportunity, perceive the contribution of direct value to the products, distinguish forms of waste, and identify...
