The global bakery industry faces persistent productivity challenges due to its high dependence on manual operations and limited technological adoption, creating substantial opportunities for process optimization. The company under study, dedicated to the production of healthy cookies made from Peruvian grains, exhibits a labor productivity of 1.46 kg/man-hour—less than half of the sector benchmark of 3 kg/man-hour—resulting in an annual economic impact of approximately 146817 USD. Key contributors to this gap include excessive setup time, prolonged cycle time, and a high defective rate. This research proposes an integrated process improvement model designed to enhance productivity in low-automation bakery environments. The model includes workplace organization through the 5S methodology, reconfiguration of preparation tasks supported by SMED principles to reduce setup time and Standardization through Standard Operating Procedures (SOPs) and Good Manufacturing Practices (GMP). Beyond operational improvements, the study contributes to engineering practice by demonstrating a quantitative framework for validating process changes through simulation, enabling data-driven decision‑making in resource‑constrained food manufacturing contexts. The findings show significant improvements: labor productivity increases by 105%, cycle and setup time decreases by 46% and 49% minutes respectively, and the defective rate drops by 86%. These results confirm that the proposed model is technically and economically viable and provide a scalable roadmap for productivity enhancement and evidence‑based engineering intervention in SME bakery enterprises.

The Peruvian wood industry faces operational inefficiencies that limit its competitiveness despite the growth of the global market. Although the country possesses abundant forest resources, low productive efficiency and high levels of informality have led to a 15.8% decrease in the sector’s international market participation between 2023 and 2024. This issue is reflected in a Peruvian company that produce solid wood flooring, where the machining stage concentrates unplanned stoppages, reducing equipment efficiency and generating economic losses and delays in order delivery.

To address these limitations, the study applied Total Productive Maintenance (TPM), through its autonomous and planned maintenance pillars, together with SMED (Single Minute Exchange of Die), in order to reduce mechanical failures and setup times. Validation was carried out through the simulation of the As-Is and To-Be scenarios in Arena, using indicators such as efficiency, availability, setup time, and MTBF.

The results show that the integration of TPM and SMED can be effectively applied to the solid wood flooring production process, a sector where no prior documented applications of these methodologies have been identified.

The simulation showed improvements of 6.6% in efficiency, 15.0% in availability, a 34.9% reduction in setup time, and a 50.8% increase in MTBF. Overall, the combined TPM–SMED approach is an effective strategy for optimizing operational performance and strengthening the competitiveness of the wood manufacturing sector.

The construction sector supply chain faces structural limitations, such as fragmentation and low integration among actors, which negatively affects project performance. In this situation, blockchain technology emerges as a possible alternative to address these challenges. This systematic review aims to recognize the impact of blockchain technology on the construction sector supply chain in terms of logistics operations, information exchange, and limitations to its implementation. The study uses the PICO approach and the PRISMA methodology for the rigorous collection, evaluation, and selection of relevant studies. The literature search was conducted in various academic databases such as Scopus, ScienceDirect, and Web of Science, obtaining a total of 374 documents, of which 31 original articles were selected after applying predefined inclusion and exclusion criteria. The results show that blockchain technology contributes to information transparency, asset and process traceability, and data integrity and security. In addition, it improves coordination among supply chain participants through secure information exchange and the use of smart contracts, which strengthens trust and reduces disputes. However, challenges related to interoperability, scalability, and investment persist, preventing the effective implementation of blockchain. The findings also include a thematic map that identifies the main lines of research and highlights emerging and declining areas, proposing opportunities for future research.

This paper presents a Systematic Literature Review (SLR) analyzing the adoption and impact of barcode-based Warehouse Management Systems (WMS) for inventory management in manufacturing environments. The review covers peer-reviewed studies published between 2021 and 2025, indexed in Scopus, and follows the PICOC framework and PRISMA guidelines to ensure methodological rigor and reproducibility. A total of 22 eligible studies were analyzed to evaluate the effects of barcode-enabled WMS on inventory accuracy, operational efficiency, productivity, and cost performance, as well as their role in comparison and integration with technologies such as RFID and the Internet of Things (IoT).

The results indicate that barcode-based WMS significantly reduce manual data capture errors and improve key performance indicators, reporting inventory turnover increases of up to 23.5%, operational productivity gains of up to 29%, and cost reductions close to 10%. Rather than competing directly with RFID and IoT, barcode technology consistently emerges as a cost-effective and reliable foundational layer within digital inventory ecosystems. The review also identifies system integration, process design, data quality, and organizational factors as critical conditions influencing successful implementation.

These findings provide engineering-oriented evidence supporting the strategic role of barcode-based WMS as a scalable backbone for inventory digitalization in manufacturing operations.

Single-Minute Exchange of Dies (SmED) focuses on identifying internal and external activities, seeking to transfer internal activities to external ones as much as possible, while minimizing internal activities. The research evaluated changes in productivity of the 3030 ml format on the production line at a carbonated beverage plant. The validity of the method and its sequence was verified, resulting in reductions in routine downtime due to format changes, an increase in effective equipment availability, and an increase in theoretical production capacity from 13,500 to 13,856 unit cases for the case study format. Improvements were achieved in process efficiency indicators, with a 3.6% increase in efficiency, a 3.7% increase in effectiveness, and an overall productivity increase of around 7.2% over a 16-week evaluation period, showing a more rational and effective use of available resources Keywords—SMED, Lean Manufacturing, Setup, Waste, Productivity.

This study evaluated the level of exposure to heat stress among kitchen workers at a food concession. The research was descriptive in scope, with a mixed approach and a non-experimental cross-sectional design. Questionnaires and the QuestTemp 34 monitor were used, applying Guideline No. 2 of D.S. No. 024-2016-EM and the ACGIH guidelines for calculating the WBGT index. The sample, selected through non-probabilistic sampling, included five workers (62.5% of the staff) in positions with high thermal loads. The results showed that globe, wet bulb, and air temperatures exceeded 34 °C, with peaks above 37 °C between 11:00 and 13:00. The clothing-adjusted WBGT index ranged from 32.88 °C to 33.02 °C, exceeding the permissible limit of 28.0 °C for moderate-effort tasks. It was concluded that the area represents a high thermal risk environment that compromises health and work performance. Consequently, a control plan was proposed that includes mechanical ventilation, scheduled hydration, active breaks, and continuous monitoring of the WBGT.
