The algorithms solve scalarization models in order to explore predetermined regions of the objective space called boxes, defined by two nondominated points. When exploring, the algorithm exploits information on its corner points and chooses the scalarization problem accordingly so as to detect line segments quickly, without having to solve many scalarizations. We propose three algorithms: The first one creates new boxes immediately when it finds a nondominated point, whereas the second algorithm conducts additional operations after obtaining a nondominated point by the Pascoletti–Serafini scalarization. The third algorithm is another variant that uses the computational advantage of dichotomic search whenever possible. Our computational experiments demonstrate the computational feasibility of the algorithms and show that the number of mixed integer linear programming models is significantly lower compared to similar approaches in the literature. The results further validate the utilization of Pascoletti–Serafini scalarization, aimed at enhancing the representativeness of solutions under time and cardinality limits. We observe that the third variant is particularly effective in finding a representative subset of the nondominated solutions under such limits.</p>","PeriodicalId":49176,"journal":{"name":"International Transactions in Operational Research","volume":"34 2","pages":"1138-1171"},"PeriodicalIF":3.5,"publicationDate":"2026-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149205387","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Monardes-Concha,&nbsp;Sergio Cruz-Zárate,&nbsp;Alfredo Candia-Véjar","doi":"10.1111/itor.70154","DOIUrl":"https://doi.org/10.1111/itor.70154","url":null,"abstract":"<p>Vaccination campaigns have saved thousands of lives and reached even the world's most remote areas. However, the COVID-19 pandemic significantly changed the strategies for such campaigns. It is now crucial to rigorously consider new factors when planning the operational aspects of these campaigns, particularly for last-mile vaccine dispensing. First, a large share of the population must be vaccinated, with emphasis on vulnerable groups at higher risk. Second, if the virus is highly contagious and capable of asymptomatic transmission, implementing public health measures at vaccination sites becomes paramount. To address these challenges, we propose a bi-objective optimization model to support healthcare decision-making. It defines a schedule for locating temporary vaccination centers and assigning populations to permanent and temporary sites over a planning horizon. Moreover, we formalize and validate a minimum set of properties for a function-based prioritization mechanism to ensure consistent prioritization. One objective prioritizes vaccinating vulnerable groups according to our novel function-based approach, while the other minimizes the operational costs of temporary centers. In the complex environment of a pandemic, the strategic integration and use of temporary and permanent vaccination centers is vital for creating a robust and responsive vaccination strategy. Temporary centers, whose locations are determined by the model, improve access for hard-to-reach groups, contribute to minimizing crowding at permanent sites, and lower infection risks. Our results, demonstrated through a case study, show that the model effectively allocates resources and generates various vaccination plans that cater to different priority levels assigned to each objective, thereby offering valuable decision support.</p>","PeriodicalId":49176,"journal":{"name":"International Transactions in Operational Research","volume":"34 2","pages":"1003-1039"},"PeriodicalIF":3.5,"publicationDate":"2026-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149206144","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper addresses this fragmentation through the first systematic cross-domain seating assignment literature review, analyzing publications via bibliometric analysis and examining assignment methods (including optimization techniques) across transportation (airplanes and trains), dining establishments, entertainment venues, and classrooms. Co-citation analysis reveals that research communities operate in separate networks despite addressing similar challenges using mathematical programming, heuristic approaches, stochastic simulation, and other operational research methods. Our cross-domain synthesis identifies technique transfer opportunities previously invisible due to research silos, such as applying restaurant group-seating strategies to airline passengers traveling together or entertainment venue considerations to dining table assignments. The review concludes that limited real-world implementation stems partly from researchers' inability to access successful approaches from adjacent fields, highlighting opportunities to advance seating assignment methods through integrated frameworks.</p>","PeriodicalId":49176,"journal":{"name":"International Transactions in Operational Research","volume":"34 2","pages":"653-737"},"PeriodicalIF":3.5,"publicationDate":"2026-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149206217","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

When the cross-effect of tax difference and vertical shareholding is large, buyer financing can hedge bankruptcy risk more effectively. With a large liquidity shock, the distressed supplier files for bankruptcy. When the reorganization cost is small or moderate, the distressed supplier reorganizes, and concession effect and bidirectional predation behavior occur in the reorganization process.

A parametric optimisation model is formulated and applied to the 2018 and 2022 FIFA World Cup draws. A flaw of the draw procedure is identified: the pre-assignment of the host to a group unnecessarily increases the distortions.

However, it is unclear how human and bot individual activities and their collaboration influence different stages of collective knowledge evolution.

Furthermore, we utilized a fixed-effect multinomial logistic model to assess the effects of these variables on the stages of collective knowledge evolution. The results indicate the distinct impacts of human/bot activities and human–bot collaboration patterns on idea generating, idea organizing, and intellectual convergence. The core findings include (1) human activities promote idea generating and organizing, whereas bot activities facilitate idea organizing; (2) human-led collaboration patterns enhance idea generating and organizing, while co-led collaboration patterns promote intellectual convergence. These findings contribute to information science and human–bot collaboration research, as well as guide platform design and community administration of OKCs.

The final dataset contained 6272 observations on the 10 ESG scores at the most detailed level possible. Based on stakeholder theory, interrupted time series analysis (ITSA) was applied to determine whether the intercorrelations among the ESG variables decreased post‐Paris. Moreover, in accordance with legitimacy theory, the reported ESG measures were examined using Benford's law. It was found that the uniformity of the last digits improved over time. Three robustness checks were carried out: (a) an out‐of‐sample ITSA with 293 STOXX‐listed companies, (b) a quadratic ITSA, and (c) placebo tests with different breakpoints. The evidence indicates (1) the downward trend became stronger in the period after the Paris Agreement and (2) the differentiation among ESG scores accelerated in a nonlinear manner. We conclude the reliability of ESG performance scores has increased over time, providing a more trustworthy foundation for stakeholders' decision‐making.","PeriodicalId":9518,"journal":{"name":"Business Strategy and The Environment","volume":"21 1","pages":""},"PeriodicalIF":13.4,"publicationDate":"2026-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149198914","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
