Achieving the UN Sustainable Development Goals (SDGs) in North Africa requires effective governance, yet the governance factors influencing SDG progress remain underexplored. Therefore, this study examines the nexus between the Worldwide Governance Indicators (WGIs) of voice and accountability, political stability and violence, government effectiveness, regulatory quality, rule of law, and control of corruption and Sustainable Development Goals (SDGs) in North Africa. Previous research has insufficiently explored the relationship between global governance progress and the 2030 agenda. To bridge this gap, we applied an integrated Grey Relational Analysis (GRA) model to compute the ranks and weights the performance of North African countries in achieving the 17 SDGs from 2016–2022. The results show that Quality Education (SDG 4), Industry, Innovation and Infrastructure (SDG 9), Reduce Inequalities (SDG10), Sustainable Cities and Communities (SDG11), Responsible Consumption and Production (SDG12) and Peace Justice and Strong Institutions (SDG16) exhibited the highest performance in the region based on Second Synthetic Grey Relational Analysis Model (SSGRA). Additionally, a conservative maximin model was used to identify which North African country has the greatest impact of WGI on SDG outcomes. The findings indicate that Morocco faced the most significant challenges, particularly in achieving SDG 6 (clean water and sanitation). These results highlight critical implications for North African governments, emphasizing the need to prioritize (clean water and sanitation) SDG 6 and implement effective national strategies. This study recommends policymakers focus on governance reforms in lagging sectors and leverage data-driven frameworks to monitor and guide sustainable development interventions.</div></div>","PeriodicalId":101201,"journal":{"name":"Sustainable Operations and Computers","volume":"6 ","pages":"Pages 198-216"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144925600","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Timely detection and effective response are important to fight against forest fires. Aviation emergency rescue plays an increasingly important role in forest fire response due to the characteristics of fast response speed, low terrain requirements and less fire site restrictions. At present, forest fire aviation emergency has been paid more attention in the world, however, current researches provide limited support to actual situation due to the lack of systematization and pertinently. In this paper, based on remote sensing information and other multi-party data, a two-stage multi-objective stochastic optimization model of sustainable aviation emergency network for forest fire rescue is presented. The proposed model aims to minimize the maximum of effective operational distance for aerial emergency rescue efforts and the total cost, which includes ecological losses caused by forest fires. To solve the model, an algorithm incorporating the NSGA-II algorithm and SAA method is proposed. Further, a case of Hainan Province in China is studied, guiding the application of the proposed theoretical methods. The findings demonstrate considerable value in addressing forest fires and safeguarding forest resources, thereby contributing to the sustainable development of both the environment and society.</div></div>","PeriodicalId":101201,"journal":{"name":"Sustainable Operations and Computers","volume":"6 ","pages":"Pages 116-129"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143898815","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Numerous original equipment manufacturers (OEMs) opt to entrust remanufacturing operations to authorized remanufacturers (ARs). Recognizing the power differences between an OEM and an AR, this paper establishes a game model based on three power structures: namely, OEM-led Stackelberg (NS model), AR-led Stackelberg (RS model) and Vertical Nash (VN model). We explore the effect of various power structures on pricing decisions and coordination in the authorized remanufacturing supply chain. Through equilibrium comparison, the following conclusions can be drawn: (1) In the RS model, the lowest authorized fee contributes to maximizing the market share of remanufactured products. However, the OEM's intellectual property is not adequately protected. In the VN model, heightened market competition will result in the lowest profit for both manufacturers. Furthermore, due to the latecomer advantage, the OEM achieves the highest profit in the RS model, while the AR earns the highest profit in the NS model. (2) In either model, implementing the carbon tax policy leads to an increase in price of both products, a decrease in the production of new products, an increase in the production of remanufactured products, and an overall reduction in carbon emissions. Notably, it is the NS model that exhibits the greatest environmental improvement. Conversely, the extent of environmental improvements in the VN and RS models depends on the consumers’ preferences for remanufactured products. (3) Through a cost-sharing contract, in which the AR collaborates with the OEM to share recycling costs, both the recovery rate of discarded products and the sales of remanufactured products increase significantly. A Pareto improvement in profits is observed when the sharing ratio exceeds a certain threshold. However, it's crucial to acknowledge that the overall profits of the supply chain do not reach the level that can be achieved through centralized decision-making. Based on this insight, a cost-sharing fixed authorized fee contract is introduced. In this arrangement, the AR compensates the OEM for its share of recycling costs by paying a fixed authorized fee, thereby facilitating supply chain coordination.</div></div>","PeriodicalId":101201,"journal":{"name":"Sustainable Operations and Computers","volume":"6 ","pages":"Pages 85-103"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143821306","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Moreover, the drawbacks of traditional supply chain network design that only considers the goal of maximizing profits or minimizing costs are becoming increasingly prominent. To this end, this study proposes a sustainable supply chain network structure for industrial production, which includes a dual-objective planning function model that maximizes profits and minimizes emissions, and a closed-loop supply chain network framework based on the product life cycle. The optimal solution of the function is obtained by using the Non-dominated Sorting Genetic Algorithms-II (NSGA-II) based on elite strategies after the improvement of immune operators. Empirical results show that the average values of time index (198), convergence measure (0.34) and interval index (623) in the improved NSGA-II algorithm are better than in other algorithms and this algorithm has clearer explanation for the decisions it made. It is also effective in helping companies choose emission reduction technologies and low-cost production facilities. With the improved algorithm, the total cost as well as carbon emissions can be reduced. The research method provides a new perspective for carbon emission management and sustainable development, and offers practical solutions for enterprises to reduce their carbon footprint and allocate resources reasonably in production and supply chain management. It helps to improve supply chain resilience and achieve sustainable development goals under economic development.</div></div>","PeriodicalId":101201,"journal":{"name":"Sustainable Operations and Computers","volume":"6 ","pages":"Pages 229-245"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145048294","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
