The objective is to understand how these elements collectively enhance competitiveness and organizational adaptability in dynamic and resource-constrained environments.</p> <p><strong>Design / Methodology / Approach:</strong> A quantitative, cross-sectional design was employed, utilizing multiple regression and correlation analyses. Data were collected from 30 companies, representing the majority of market research firms in Huancayo, where the total population does not exceed 50. The methodological framework incorporated structured surveys and Ordinary Least Squares (OLS) estimations, with robust validation procedures and adherence to statistical assumptions. A power analysis based on Cohen’s criteria confirmed a high level of statistical power despite the modest sample size.</p> <p><strong>Results</strong>: The findings reveal that 88.7% of the variability in process optimization is explained by independent variables, with technological innovation showing the strongest impact (coefficient: 0.743, p&lt;0.001). Customer empowerment, with the highest mean (17.87) and a strong correlation to digital technologies (0.859), underscores the shift towards customer-centric strategies.</p> <p><strong>Limitations of the Investigation</strong>: The cross-sectional nature of the study restricts causal inference, and the limited sample size—though representative of the local population—may reduce generalizability and sensitivity to subtle effects. Future studies should employ longitudinal designs and larger samples across multiple regions to validate and extend these results.</p> <p><strong>Practical Implications</strong>: The study underscores the importance of integrating digital tools to enhance operational efficiency, foster continuous innovation, and strengthen client engagement. For firms in emerging markets like Peru, particularly in mid-sized cities such as Huancayo, cultivating a culture of digital adaptability and investing in human capital are essential steps toward sustainable competitiveness in the digital era.</p> <p><strong>Originality / Value</strong>: By analyzing digital transformation through a multi-dimensional lens, this research contributes to the literature by providing actionable insights into leveraging technology for operational efficiency and customer empowerment in a developing economy context.</p> 2025-08-11T00:00:00-03:00 Copyright (c) 2025 Paulo César Callupe-Cueva, Augusto Aliaga-Miranda, Luis Ricardo Flores-Vilcapoma, Christian Efrain Raqui-Ramirez, Bernabé Teodoro Vila-Hinojo, Wilmar Salvador Chavarry-Becerra https://bjopm.org.br/bjopm/article/view/2345 A DEMATEL-based analysis of logistics determinants in online retail 2025-05-07T11:56:07-03:00 Nicollas Luiz Schweitzer de Souza Schweitzer nicollas_schweitzer@hotmail.com Marina Bouzon marinabouzon@gmail.com Diego de Castro Fettermann d.fettermann@ufsc.br Enzo Morosini Frazzon enzo.frazzon@gmail.com <p><strong>Goal</strong>: The objective of this study is to perform the analysis of the logistical determinants for the purchase of a product online through the DEMATEL methodology.<br /><strong>Design/methodology/approach:</strong> The factors that drive a customer to make a purchase online have become competitive and make it so that the customer can quickly compare online sales platforms and then select the one that is most attractive to them. This study sought through the DEMATEL methodology to identify with experts in the area, factors that lead a customer to make a purchase decision in an online retail in the logistics context.<br /><strong>Results</strong>: The results show that the experience that the retailer delivers to the customer in the delivery logistics process is totally directed with the purchase decision and that this is a focus factor of the specialists in the decision-making process.<br /><strong>Research limitations:</strong> Some data on logistics factors, customer preferences, or purchasing behavior may compromise the accuracy and reliability of the analysis results. Practical implications: Understanding the factors, businesses can optimize their supply chain processes to meet customer demands efficiently, reducing lead times, stockouts, and delivery delays. This may involve renegotiating contracts with shipping providers, investing in warehouse automation technology, or optimizing transportation routes to reduce costs and improve overall operational efficiency.<br /><strong>Originality/value</strong>: Few studies have applied DEMATEL to logistics issues, especially in the context of online retail. This article seeks to point out indicators for decision-making that are rarely studied in the literature and that serve as a new way of helping managers make decisions.</p> 2025-07-29T00:00:00-03:00 Copyright (c) 2025 Nicollas Luiz Schweitzer de Souza Schweitzer, Marina Bouzon, Diego de Castro Fettermann, Enzo Morosini Frazzon https://bjopm.org.br/bjopm/article/view/2570 A reactive hybrid product-driven system for rescheduling in a manufacturing planning 2025-04-21T13:41:53-03:00 Patricio Sáez Bustos patricsaez@udec.cl Victor Parada Daza victor.parada@usach.cl <p class="RESUMOBJO"><span lang="EN-US"><strong>Goal</strong>: </span><span lang="EN-US" style="font-weight: normal;">This research aims to develop a novel scheduling model integrating the intelligent product paradigm of a product-driven system (PDS) with the shifting bottleneck heuristic (SBH) to enhance rescheduling efficiency and adaptability in dynamic job shop scheduling problems with disruptions (JSSP-D).</span></p> <p class="RESUMOBJO"><span lang="EN-US"><strong>Design / Methodology / Approach</strong>: </span><span lang="EN-US" style="font-weight: normal;">The model employs agent-based modeling, where products act as autonomous agents in rescheduling decisions. Simulations covered 151 scenarios across 14 benchmark instances of machine failures, with production time increases of 100%, 200%, and 300%. The model’s performance was evaluated on its ability to minimize makespan deterioration and maintain efficiency under different disturbance levels.</span></p> <p class="RESUMOBJO"><span lang="EN-US"><strong>Results</strong>: </span><span lang="EN-US" style="font-weight: normal;">The PDS-SBH model effectively reduced production efficiency gaps, achieving an average makespan reduction of 7.81%, with peaks of 36.06%. Higher disturbance levels allowed for better rescheduling outcomes, albeit with increased variability. The model’s adaptability provided solutions comparable or superior to stable scheduling benchmarks.</span></p> <p class="RESUMOBJO"><span lang="EN-US"><strong>Limitations of the investigation</strong>: </span><span lang="EN-US" style="font-weight: normal;">The study used 14 benchmark instances and focused solely on machine failures, limiting generalizability to other disruptions like resource shortages or order changes.
