Each short period, the retailer determines a stocking quantity before random demand is realized. Strategic customers use their reference on product availability to purchase at a regular price or wait for a markdown and learn from the retailer’s stocking quantity to update their reference. We characterize the structural properties such as the concavity of single- and two-period profit functions. On an infinite horizon, we show that a steady-state reference distribution is ergodic and an optimal stocking quantity is unique for a given reference. We conduct extensive numerical studies on an infinite horizon to compare an optimal dynamic policy and the corresponding optimal static policy which sets a fixed stocking quantity over time. A near-optimal performance of optimal static policy with an average profit gap of less than 1% is remarkable and contrasts with that in the two-period model which may be far worse. Thus, a well-chosen fixed stocking quantity on a planning horizon with many short periods tends to yield a high performance without having to change stocking quantities over time.</p></div>","PeriodicalId":8215,"journal":{"name":"Annals of Operations Research","volume":"344 1","pages":"47 - 78"},"PeriodicalIF":4.4,"publicationDate":"2024-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142912776","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}

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}
