This problem is amplified in the case of e-commerce due to both high volume and high velocity of information. Specifically, it is hard to find labels for mass online reviews, rendering it unsuitable for supervised learning. Till date, the most sought solution is manual labelling, which remains a labour-intensive and time-consuming task. The purpose of this study is to develop an end-to-end approach for identifying the sources of quality-stimulated customer dissatisfaction and automatically assigning them in the context of e-commerce. The above objective is achieved by using a novel ensemble-based semi supervised pseudo-labelling technique on a large corpus of Amazon.com reviews. As a first step, a subset is manually labelled, followed by an ensemble approach of retaining commonly labelled (pseudo) class to iteratively label the entire dataset. We then apply Large Language Models (LLMs) and Deep Learning (DL) architectures on the (pseudo) labelled data to accomplish a multi-class classification problem. We contrast and showcase statistically significant improvement to the baseline machine learning models, where the pre-trained transformer models demonstrate best performance. Our approach proposes a roadmap to streamline automatically identifying sources of quality-related dissatisfaction in e-commerce channels using an amalgamation of ensemble and sophisticated computational techniques. We believe that our approach, if adopted, can bolster grievance redressal for online customers.</p></div>","PeriodicalId":8215,"journal":{"name":"Annals of Operations Research","volume":"353 2","pages":"545 - 574"},"PeriodicalIF":4.5,"publicationDate":"2025-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145296554","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}

Anchored in SDG 13, this study focuses on the operational and low-carbon research and development (R&D) issues faced by firms in a supply chain, comprising one supplier and one manufacturer, in two scenarios: cooperative decision making and independent decision making. The independent decision-making scenario is classified into three modes: supplier-independent R&D, manufacturer-independent R&D, and two firms simultaneously R&D. First, this study evaluates the various modes with regard to unit abatement levels, corporate profits, environmental impact, and consumer surplus. Next, the analysis investigates the influence of carbon tax and R&D cost coefficient on equilibrium strategy. Our findings indicate that under the cooperative mode, when the cost coefficient is below a certain threshold, a high carbon tax can effectively incentivize both firms to increase their carbon reduction efforts, thereby enhancing the overall profitability of the supply chain and advancing the achievement of the SDG 13. The simultaneous independent R&D can enable all parties to obtain a high unit abatement level than when a single firm conducts independent R&D. In addition, the simultaneous R&D mode of two firms can generate higher profits and consumer surplus than the R&D mode of a single firm, and can bring higher total supply chain profits than the cooperative mode when the R&D cost is low. After extending modes to the case where the two firms cooperate only in the field of R&D, this study finds that the unit abatement level reaches the maximum.</p></div>","PeriodicalId":8215,"journal":{"name":"Annals of Operations Research","volume":"352 1-2","pages":"295 - 324"},"PeriodicalIF":4.5,"publicationDate":"2025-08-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145037453","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}

The proposed analysis is based on the roots of the characteristic equation associated with the LST of the waiting-time distribution (in the queue) of a random customer. Using LSTs, the closed-form expressions for the probability density functions and for an arbitrary number of moments of the waiting-time distributions have been presented.

Considering a complementary supply chain consisting of a supplier and a manufacturer, where the manufacturer assembles components produced in-house and by the supplier into one final product. The government aims to enhance social welfare or LCI product innovation levels. To this end, the government has four potential subsidy strategies: supplier subsidy, manufacturer subsidy, consumer subsidy, and low-carbon infrastructure subsidy. Our research shows that first, although subsidizing low-carbon infrastructure can enhance social welfare, it offers minimal improvement in product LCI. Second, subsidies directed towards suppliers yield limited advancements in social welfare and LCI. Third, when consumers are price-sensitive, subsidizing the manufacturer can maximize both LCI and social welfare. Conversely, when consumers are LCI-sensitive, allocating subsidies toward the supplier is more beneficial. In summary, our research extends the existing literature on complementary supply chain management by identifying the optimal subsidy for the government to achieve its goals, offering tangible insights into practical pathways for realizing SDG 7, 9, 12, and 13 through targeted policy design.</p>\u0000 </div>","PeriodicalId":8215,"journal":{"name":"Annals of Operations Research","volume":"352 1-2","pages":"325 - 349"},"PeriodicalIF":4.5,"publicationDate":"2025-08-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145037255","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}
