A large number of the extant studies have tried to address such a practical problem with using various algorithms for one or more runways. For a static single-runway of the ALP, this paper proposes a new approach to develop an alternative powerful algorithm. For a given sequence of planes, we develop a faster algorithm for solving the ALP with the running time <span>(O(n log n))</span>, where <i>n</i> is the number of aircrafts in the schedule. Alternatively, we reduce the proposed problem of minimizing the total cost by determining the landing times for a given landing sequence into a min-cost flow problem. We conduct a set of experimental studies to compare the performance of our near-linear time algorithm to the quadratic time algorithm whose time complexity is <span>(O(n^2))</span>, for computing the optimal landing times. The computational results show that the proposed heuristic based on our algorithm could be much faster than both such quadratic time algorithm and the one using linear programming.</p></div>","PeriodicalId":8215,"journal":{"name":"Annals of Operations Research","volume":"344 1","pages":"479 - 498"},"PeriodicalIF":4.4,"publicationDate":"2024-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142912890","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using advanced machine learning techniques, including multi-label classification and BERT-based sentiment analysis, the research highlights the key environmental, social, and economic dimensions that consumers prioritize. The findings reveal a significant misalignment between consumer concerns, reflected in social media discourse, and the focus of corporate sustainability reports. While companies emphasize environmental impacts and supply chain management, consumers prioritize product reliability, community obligations, and educational initiatives. This gap indicates a need for companies to realign their sustainability strategies to better meet consumer expectations, emphasizing trust-building, community engagement, and educational efforts. Despite these differences, the study also identifies shared concerns between consumers and producers, such as environmental impacts, supply chain sustainability, and transparency in sustainability claims. Based on these insights, the study recommends fostering transparent communication, engaging in inclusive dialogue, and committing to accountable actions across all sustainability dimensions. By aligning corporate reporting with consumer expectations, this research provides guidance to help companies advance towards a circular economy and enhance Extended Producer Responsibility (EPR) in the electronics industry, ultimately benefiting both companies and consumers in the pursuit of a more sustainable future.</p></div>","PeriodicalId":8215,"journal":{"name":"Annals of Operations Research","volume":"345 1","pages":"317 - 349"},"PeriodicalIF":4.4,"publicationDate":"2024-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10479-024-06343-4.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143108994","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Non-parametric Bayesian methodology is used to unpack between-group differences in approval probabilities associated with gender and country of origin and identify (demand-side differences), while differences in unexplained approval probabilities would suggest supply-side biases. The empirical analysis shows that applicants coming from outside of the European Union tend to be more productive than EU-born citizens. They also enjoy a higher approval probability, except for applicants from Latin America, which appear to be riskier borrowers. This result suggests that the microcredit provider treats immigrants fairly. By contrast, the higher productivity and the lower risk of female entrepreneurial projects is only partially compensated by easier access to credit.</p></div>","PeriodicalId":8215,"journal":{"name":"Annals of Operations Research","volume":"344 1","pages":"103 - 134"},"PeriodicalIF":4.4,"publicationDate":"2024-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142912747","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, overseas production comes with yield uncertainty. This study examines optimal environmental regulations and firms’ responses under three production scenarios. The government’s objective is to maximize social welfare by selecting the type and intensity of regulatory instruments, while firms seek to optimize profits by adjusting their optimal production quantities. Our analysis finds that price and quantity regulation instruments have similar impacts on social welfare, but firms prefer quantity instruments despite price instruments being more beneficial for consumers. Furthermore, both pollution damage coefficient and yield uncertainty are important factors affecting social welfare and firms’ location choice and there exist win–win situations that benefit the government, firms, and consumers. Additionally, offshoring tends to be more environmentally friendly to the local environment. To further validate the main model, we examine various extensions. Results show that the hybrid instrument does not significantly enhance social welfare, but it does offer flexibility in adjusting firms’ production transfer motivations. Additionally, factors such as positive production and fixed costs, as well as multi-market issues, do not alter the government’s preference for regulatory instruments.</p></div>","PeriodicalId":8215,"journal":{"name":"Annals of Operations Research","volume":"344 1","pages":"413 - 456"},"PeriodicalIF":4.4,"publicationDate":"2024-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142913067","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
