The first phase is an assessment of ground vegetation cover by upervised classification of the city using satellite images. Concurrently, 3D modeling of structures is undertaken using LIDAR point cloud classification, combining the extraction of building footprints using photogrammetric restitution. This approach provides a precise three-dimensional depiction of the urban topography. The evaluation of the feasibility of each roof for the introduction of vegetation is based on a complicated Boolean multicriteria analysis. This technique includes essential elements such as minimum roof size, slope, and duration of sunshine, utilizing the linear model of Angstrom Prescott as a reference. These challenging criteria lead to a rigorous assessment of the effective area of each roof, therefore finding suitable roofs for the smooth integration of green roofs into the urban environment. The investigation showed a broad distribution of roofs in Nador in terms of potential for green roofs. The medium category, containing 18<!--> <!-->521 buildings with available space between 30% and 60%, demonstrates considerable potential, while the high level of quality is attributable to 2695 structures with over 60% available space, presenting substantial possibilities for greening. The combination of these groups constitutes 64% of the total roof area, showing a considerable percentage favorable to greening. Economically, the research comprises an in-depth examination of expenses connected with green roof installation, varied greatly depending on the style of roof (extensive or intense), ranging from $28.95 to $96 million. Concurrently, an evaluation of the economic advantages of urban agriculture on rooftops is done, with possible revenues estimated at $8.11 to $12.16 million depending on the variety of crops. Despite large initial expenses, this research demonstrates that investments in green roofs may offer long-term economic and environmental advantages, considerably contributing to ecological urban design. The collected findings are applied to construct a green cadastre, giving a strong platform for GIS mapping of ideal roofs, so permitting a planned and harmonic integration of green roofs into the urban fabric of Nador.</div></div>","PeriodicalId":100598,"journal":{"name":"Green Technologies and Sustainability","volume":"3 2","pages":"Article 100171"},"PeriodicalIF":0.0,"publicationDate":"2025-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143167421","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Through an extensive review of 480 peer-reviewed papers retrieved from the Scopus database, using the keyword search “blockchain” and “management” or (“manufacturing” or “industrial engineering” or “service” or “supply chain” or “organization”) within the title, abstract, and keywords, this study highlights BCT’s ability to revolutionize supply chain management by providing real-time traceability, automating processes through smart contracts, and ensuring sustainability and compliance. The study finds that BCT significantly enhances management and industrial engineering by improving supply chain transparency, automating operations with smart contracts, and ensuring quality and sustainability. Key findings reveal its effectiveness in improving data security, risk management, and intellectual property protection, alongside optimizing inventory control and customer satisfaction. Moreover, the study identifies innovative applications of BCT in integrating digital technologies such as IoT within Industry 4.0 frameworks, enabling smarter and more resilient manufacturing systems. By addressing challenges such as scalability, regulatory uncertainty, and interoperability, this review offers a roadmap for organizations to adopt BCT effectively. The novelty of the study lies in its comprehensive analysis of BCT’s dual potential, i.e., bridging operational gaps and fostering strategic alignment while providing actionable insights for practitioners to leverage its benefits across diverse industrial applications.

As environmental sustainability concerns grow, there is a need to explore alternative fuel options and vehicle technologies with reduced emissions. In this study, a comparative analysis is conducted on three distinct vehicle types — hybrid, diesel, and biodiesel — assessing their carbon footprint based on emissions of CO<sub>2</sub>, CO, NOx, SO<sub>2</sub>, PM and UBHC across various operating conditions such as load, efficiency losses, and torque. The Analytic hierarchy process (AHP) method was used to determine the weights for various output parameters, including, the weights assigned to these parameters are as follows: CO<sub>2</sub> emissions-13.76%, CO emissions-18.29%, UBHC emissions-25.58%, NOx emissions-13.54%, PM emissions-7.01%, and SO<sub>2</sub> emissions-21.83%. Various vehicle types were ranked using the Evaluation Based on Distance from Average Solution (EDAS) approach. The experimental findings show that, out of the three vehicle types, hybrid vehicles had the best emissions profile, with lower levels of all assessed pollutants. Consequently, hybrid vehicles are identified as having the lowest carbon footprint, followed by diesel vehicles, with biodiesel vehicles exhibiting the highest emissions. K-means clustering is used to determine which type of vehicle is most effective at reducing emissions. With emissions of 95 g/km, 0.2 g/km, 0.015 g/km, 0.02 g/km, 0.001 g/km, and 0.005 g/km for CO<sub>2</sub>, CO, UBHC, PM, and SO<sub>2</sub>, the hybrid car in cluster 1 yields the most promising results.
