- Evaluating the role of digital technologies in enhancing warehouse efficiencyPublication . Perkumienė, Dalia; Samuolaitis, Mindaugas; Hasanov, Jamil; Dinis, Maria Alzira Pimenta; Safaa, Larbi; Leal Filho, Walter; Perkumienė, Dalia; Dinis, Maria Alzira PimentaThis article evaluates the role of digital technologies in enhancing warehouse efficiency, using Amazon as a case study. Over the past few years, the corporation has been using its new technology capabilities to create digital solutions that increase operational efficiency. Digital technology offers significant advantages in areas including accuracy, productivity, information sharing, and inventory control. Therefore, the study’s primary goal is to assess the digitalization solutions that enhance Amazon’s warehouse operations. For this work, a qualitative research methodology was employed, and data was gathered via SWOT analysis and semi-structured interviews. Seven Amazon employees involved in warehouse operations participated in the study. Warehouse management systems (WMS), RFID technology, Internet of Things (IoT)-enabled sensors, robotics (such Kiva robots), machine learning, and cloud platforms are some of the important digital tools utilized in Amazon’s warehouse operations. The implementation of these technologies led to a 99% increase in inventory accuracy, a 60% reduction in error rates, a 30% decrease in labor dependency, and a 25% reduction in order picking time. In addition, online data tracking was enhanced, particularly using RFID and IoT tools, which increased decision-making speed and accuracy. Staff training issues, incompatibility with outdated systems, and brief technological hiccups were among the obstacles to digitization. However, the total advantages of modernizing an organization and integrating new technology into its structure outweigh all of these, according to research participants. Under headings like artificial intelligence and machine learning, the reviewers claim that the digitization process has significantly improved a company’s warehouse operations.

- Social, economic, and environmental impacts of renewable energy technologiesPublication . Bushra Husnain; Narcisa Smječanin Omerbegović; Hamaguchi, Yoshihiro; Roquyya Khatoon; Alexander Chupin; Asia Nosheen; Liviu Cătălin Andrei; Dinis, Maria Alzira Pimenta; FarooqThe escalating impacts of climate change and the depletion of fossil fuels necessitate a global transition to renewable energy technologies (RETs). This chapter explores the social, economic, and environmental impacts of RETs, aiming to assess their role in achieving sustainable energy goals. The primary objectives include evaluating how RETs influence job creation, air quality, public health, and gross domestic product growth, while addressing social acceptance and equitable energy access. Methodologically, the chapter synthesizes data from global case studies, surveys, and empirical research between 2010 and 2024, offering a multidimensional perspective. In 2024, global CO2 emissions reached 41.6 billion tons, prompting a critical shift toward RETs like solar, wind, bioenergy, and hydropower. Notably, RETs could reduce global greenhouse gas emissions by up to 90% by 2050 and potentially prevent 2.5 million premature deaths annually due to improved air quality. Employment in renewables rose to 13.7 million by 2022, with projections of 35 million jobs by 2050. The novelty of this chapter lies in its integrated assessment approach, combining technological advancements with social and economic metrics, while highlighting research gaps in equity, policy, and life cycle emissions. Future applications include developing equity-aware planning tools, digitalized energy grids, and policies supporting just transitions for marginalized groups. The findings offer a robust framework for future policymaking and guide the equitable implementation of RETs in the global energy transition.
