In this study, we explore the problem of compatible strategy considering an LRP with awareness and valuation advantages and an SRP. In the compatible case, customers can return their used products directly to LRP through its recycling platform or to SRP through either LRP’ s compatible channel or SRP's own platform. Additionally, numerous recycling platforms have been adopting a sorted policy to enhance their profitability. Our major research findings are as follows: First, due to complex relationships in co-opetition case, increasing awareness advantage may have negative impacts on LRP's profit. Second, while the recycling platforms’ equilibrium strategies under unsorted recycling are always the same, under sorted recycling, they differ when the valuation advantage falls within an intermediate range. Third, under sorted recycling, despite its valuation disadvantage, SRP's profit may exceed LRP's when the unit reuse profit of recycled products is high. Finally, regardless of sorted recycling, while social welfare always benefits from the compatible channel, consumer surplus consistently deteriorates. Our findings not only provide important implications for recycling platforms to implement compatible strategies to achieve win–win outcomes but also suggest that governments should adopt a balanced approach in regulating recycling platforms under sorted recycling initiatives.","PeriodicalId":49176,"journal":{"name":"International Transactions in Operational Research","volume":"33 5","pages":"3051-3087"},"PeriodicalIF":2.9,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147684088","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}

The definition of success can be broadened to include other concepts of accomplishment rather than focusing solely on the identity of the tournament winner. Manipulation can be done in favor of diverse stakeholders. Each stakeholder may have a different goal to maximize concerning its party of interest—a player or a set of players. To formalize this, we use a weighted tournament graph model and define a score function that measures the success of the party of interest. Given the match outcome for any pair of players, we analyze the complexity of performing the manipulation for various manipulation types. We consider manipulation in favor of a single player achieving the highest score in the tournament and in favor of a set of players achieving a higher score than the complementary set. Furthermore, using the suggested model, we analyze the complexities of the manipulations done in favor of a particular player or set that wishes to prevail over another player or set. We define problems that address these types of manipulation and analyze their complexity. Although the general problems are NP-complete, we show broad scenarios in which the problems are polynomial-time solvable.","PeriodicalId":49176,"journal":{"name":"International Transactions in Operational Research","volume":"33 5","pages":"3110-3127"},"PeriodicalIF":2.9,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/itor.70044","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147683262","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To examine these effects, we develop a dynamic game model consisting of a car manufacturer (M), a retailer (R), and a car-sharing platform (hereafter referred to as the platform) to investigate the impact of the platform's adoption of specialized EVs on supply chain members, consumers, and total carbon emissions (TCE). Analytical results show that the adoption level of EVs can affect M's channel choice when the service quality of the platform is high enough. Furthermore, when M selects dual channels, increasing the adoption level of EVs has a positive impact on R's profit, a negative impact on the profits of M and platform, and a nonmonotonic impact on the total profit of the supply chain; Moreover, as the adoption level of EVs increases, consumer surplus may decrease, the TCE of both fuel and electric vehicles may initially decrease and then increase, and the social welfare may initially increase and then decrease. Finally, if the production cost of EVs is high while the production cost of fuel vehicles is low, the platform should not adopt EVs. However, if the production costs of both types are high, the platform should adopt EVs.","PeriodicalId":49176,"journal":{"name":"International Transactions in Operational Research","volume":"33 5","pages":"2950-2976"},"PeriodicalIF":2.9,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147684054","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}

Yu, Pham Tuan Anh","doi":"10.1111/itor.70018","DOIUrl":"10.1111/itor.70018","url":null,"abstract":"This research studies the electric vehicle routing problem with time windows, partial recharges, and covering locations (EVRPTW-PR-CL), as an extension of the electric vehicle routing problem with time windows and partial recharges (EVRPTW-PR), where covering locations (CLs) are facilities equipped with parcel lockers (PLs) and charging stations (CSs). The presence of PLs offers customers an alternative delivery option, where they are provided incentives to collect their parcels themselves, called self-pickup (SP) services. The objective is to seek routing plans that minimize the sum of travel costs, fixed operational costs for used EVs and CLs, and compensation paid to customers served by SP. To solve the problem, we derive a mixed-integer programming model and design an effective variable neighborhood search (VNS) algorithm coupled with problem-specific neighborhood operators, a dynamic programming procedure for optimal CS insertions, and a tailored set partitioning formulation (SPF) to enhance solution quality by utilizing collected routes so far. Numerical experiments are conducted on benchmark instances. VNS not only provides new best-known EVRPTW-PR solutions but also solves EVRPTW-PR-CL instances efficiently. Lastly, we present the effects of delivery options and compensation, offering insights that help decision makers design more sustainable and cost-effective last-mile delivery networks.","PeriodicalId":49176,"journal":{"name":"International Transactions in Operational Research","volume":"33 5","pages":"3187-3225"},"PeriodicalIF":2.9,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147683745","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}
