This article comprehensively reviews the implementation and impacts of Lean Manufacturing in the plastics industry, with the aim of synthesizing and evaluating how the adoption of these methodologies has contributed to improving efficiency, reducing costs and optimizing production processes. Using a systematic review methodology, 97 relevant articles were selected. The main results of the review indicate that Lean not only improves operational efficiency and reduces waste significantly, but also encourages the integration of advanced technologies such as Industry 4.0. In addition, a strong focus on sustainability is observed, with Lean facilitating practices that support environmental conservation and carbon footprint reduction. In conclusion, while Lean Manufacturing has proven to be an effective tool for improving operations, its effective implementation requires tailored approaches th...

The objective of this article was to design an inventory control system for a toy store in Puyo, Ecuador. Between November 2018 and February 2019, we characterized the actual situation of inventory management in the company in the first stage of the research; in the second stage, we designed the inventory system. For the analysis and design of the inventory management system of the toy store we combined two procedures, one unrelated to the characterization of the existing inventory system and the other related to inventory planning. We identified that the merchandise in the store was not codified and that the store lacked a storage system for its merchandise. We discovered that the stock available could not be identified. In addition, we determined the inventory parameters as a basis for the design of the automated system. An adequate inventory management will guarantee a timely supply o...
