This article presents a Systematic Literature Review (SLR) on how Artificial Intelligence (AI) acts in the optimization of these processes. The research was conducted across the Scopus, IEEE Xplore, and Web of Science databases, covering the period from 2015 to 2025, resulting in a final portfolio of 31 validated articles after screening 258 raw records. The results demonstrate that Deep Learning techniques, such as Long Short-Term Memory (LSTM) and Convolutional Neural Networks (CNN), are considered benchmarks in Remaining Useful Life (RUL) prognosis, showing accuracy levels exceeding 95%. It is evident that the integration of Edge Computing architectures is fundamental to overcoming low connectivity in the forestry sector. Thus, it was found that AI not only increases fleet availability but also serves as a strategic element for reducing operational costs and strengthening Environmental, Social, and Governance (ESG) practices in the industry.

This study proposes improvements to the biweekly preventive maintenance (P15) process in an automotive workshop for a forestry fleet in Mato Grosso do Sul, through the integration of time and motion study, qualitative diagnosis, and discrete event simulation. Thirty-five P15 maintenances were timed over a 12-week period (June-August/2025), identifying an observed average time of 115 minutes. Qualitative diagnosis via Ishikawa Diagram with 15 interviewees indicated method and layout as the main causes of inefficiencies (67% of mentions). The Arena simulation model was parameterized with normal distributions N(μ,σ) derived from empirical data and statistically validated (simulated mean time 115.02 min vs. observed 115.00 min; p = 0.787). The proposed scenario integrated layout reorganization (total path reduction from 418.9 m to 183 m), implementation of standardized operating procedures, and reordering of inspection sequence. Results demonstrated a 25.45% reduction in average cycle time (from 115.02 min to 85.75 min; p < 0.001), decrease in Box P15 utilization from 81.0% to 58.9%, and elimination of waiting time. Sensitivity analysis with ±10% variation in critical parameters confirmed robustness of results. The study indicates technical feasibility of implementation and offers a replicable methodological protocol for similar heavy automotive maintenance operations.

Thus, this study aims to propose a plan for implementing Total Quality Management (TQM) for an earthmoving company, which was guided by the use of the 5W2H tool and by an analysis of the company's organizational maturity. The specific objectives of this study include identifying the advantages and difficulties of implementing TQM, assessing the company's maturity level, and proposing improvements aimed at satisfying the needs of stakeholders. The research is characterized as a case study and was conducted through the application of a structured questionnaire and on-site observations, complemented by informal conversations with the manager. The results indicated that the organization is in stage 1 of maturity, characterized by poorly systematized processes and predominantly reactive actions. The main weakness identified was internal communication, which hinders the development and execution of strategic action plans. However, it was found that the adoption of TQM can generate significant benefits, such as increased operational efficiency, improved service quality and reliability, and strengthened relationships with customers and employees.

This study aimed to analyze, through a literature review, how noise has been addressed in productive environments and what control strategies have been proposed within the context of operations management. The adopted methodology was a qualitative bibliographic review, based on 58 technical-scientific articles published between 2015 and 2025, obtained from databases such as SciELO, CAPES, Engineering Village, BDTD, among others. The analysis was structured around four categories: noise as a physical risk, effects of Noise-Induced Hearing Loss (NIHL), diagnostic and monitoring methods, and the integration of strategies with management systems. The results show that noise control still relies mainly on the use of Personal Protective Equipment (PPE), with limited implementation of engineering solutions and weak connection to ergonomics, layout, or maintenance routines. In most cases, sound data—when collected—do not influence operational decisions. The study concludes that noise can be treated as a technical variable, acting as a signal of failure and as a decision-making indicator for safety, work organization, and system performance.
