Lean Warehousing emphasizes waste reduction and continuous improvement, positioning itself as a key approach to optimizing logistics operations. The objective of this research is to analyze how the Lean Warehousing methodology enhances the effectiveness of warehouse management in the manufacturing industry. To achieve this, the PRISMA methodology was employed, identifying 105 studies. Based on specific selection criteria, 16 studies were chosen for the final analysis. According to the results, warehouse efficiency significantly increased. From a quantitative perspective, key performance indicators such as OEE (86.3%) and order fulfillment rate (95.6%) improved, along with reductions in processing times and variability in warehouse logistics processes. From a qualitative perspective, space utilization was optimized, working conditions improved, and organizational culture was strengthened, fostering satisfaction and collaboration among teams.It is concluded that warehouse management efficiency metrics improve with the application of Lean Warehousing techniques such as 5S, Kanban, Kaizen, and SMED.

Inadequate plastic waste management poses a pressing environmental challenge, driving the need to adopt sustainable business models based on circularity. This research explores the feasibility of establishing the first commercial-scale chemical recycling plant in Colombia, focusing on the transformation of post-consumer polyolefins into new plastics or circular polymers. Through a regulatory, commercial and supply feasibility analysis, together with a financial evaluation using the free cash flow method, we seek to build a business model adapted to the Colombian market. Financial viability, in particular, focuses on determining whether the project's future profits are sufficient to cover costs, operating expenses, and initial investment, ensuring an attractive return for investors. This analysis is based on current global economic indicators and the industrial and technological particularities of the recycling sector in Cartagena and the Caribbean region.

In the current context, efficiency has become an essential element for small and medium-sized enterprises (SMEs), driven by an increase in demand that forces them to remain competitive. Over the course of 2022, the chemical products sector experienced a notable growth of 16.2% compared to 2020. However, productivity is threatened by various factors, including lack of organization in facilities, downtime, and manufacturing of products that fail to meet required quality standards. This directly impacts the company's profits, resulting in economic losses solely due to fines. Therefore, through engineering tools such as TPM, numerous advantages can be obtained that will be essential for gradually improving high levels of order delivery non-compliance to customers. The central objective of this study is to enhance productivity by identifying critical factors, such as the existence of inefficient processes (29%), lack of cleanliness and order (26%), and inadequate plant design and layout (23%). The proposed model in this research is based on the implementation of 5S and SLP methodologies, aimed at reducing downtime, enhancing process efficiency, and decreasing the proportion of products failing to meet quality standards. In summary, this proposed model achieves its goal of increasing productivity by reducing transfer time to a maximum of 20 minutes.

This recent investigation has the objective of improving the inventory management of the agricultural company Andrea SAC via the implementation of RFID technology, Cycle Counting based on Multicriteria ABC Analysis and Systematic Layout Planning. Finally, the goal is to increase the Inventory Record Accuracy (ERA). On other things, the investigation is going to be based on the application of every single tool mentioned with the goal of solving the root causes that are generating the low Inventory Record Accuracy problem. To achieve this, we need first to determine the background of the agricultural sector and grape exports, while highlighting the reasons why this topic was chosen, and the research related to this problem. Also, we´re going to detail the ways RFID technology helps us to improve the accuracy in inventory counting, the recommended counting frequency to do for every inventory group (A, B or C) with the objective of increasing the ERA indicator and maximizing the visibility of every SKU using Systematic Layout Planning.

The main objective of the study was to evaluate the level of efficiency of a jewelry and precious metals production line. According to this detailed analysis, proposals for improvements were made focused on the efficiency of the production process and, in this way, being able to substantially improve the downtime of the machines and the operators involved in the process. The work presents a robust theoretical framework with the necessary knowledge to better understand the various tools and methodologies that will be used for the analysis and proposal for improvement. The methodology used includes a detailed analysis of current processes, the identification of bottlenecks and the implementation of the Lean tools. The TPM tool has been used to ensure proper and continuous maintenance of machines, reducing downtime and improving equipment life. Kanban cards have been implemented to manage and control the workflow, guaranteeing an adequate supply of necessary materials and components at the right time. The main indicator evaluated is the general efficiency of the machining area, measured before and after the implementation of the improvement model. The results obtained show a significant increase in efficiency levels, reflected in the reduction of cycle times, increased production and decreased operating costs. This study highlights the effectiveness of Lean tools in improving processes within the jewelry industry and its potential application in other manufacturing sectors. The result was a significant increase in efficiency from 48.9% to 67% with the sand simulation.

In the textile sector, managing finished product inventories is crucial to ensure profitability and operational efficiency. This article focuses on reducing the overstock of finished products in the domestic line. The importance of addressing this problem is highlighted mainly to reduce the loss of utility in the domestic line. Through a detailed study of the case of the company Textil El Amazonas S.A., it is analyzed that this problem has a negative economic impact of S/ 2,512,067.3 caused mainly by poor production planning, poor inventory management and error in the amount of yarn production. Based on this, it is proposed to reduce the first, second and third causes with the implementation of the Sales & Operation Planning (S&OP) methodology and the second cause with the implementation of the Vendor Management Inventory (VMI) methodology. With the application of these methodologies, it is expected to reduce the technical gap proposed in the research by at least 13%. Likewise, it is intended to reduce the average absolute deviation of the demand forecast by 15% of the current one. Finally, it is expected to increase the inventory turnover rate and the ERI indicator.
