However, the emergence of privacy-preserving allows users to control their personal information to minimize privacy losses. This paper investigates how competing digital businesses invest in user information collection and set information pricing, and whether they should allow users to opt out of personal information tracking or even control information authorization. We develop a game-theoretic model to examine the impact of user information control on the information strategies of competing digital businesses. In this model, digital businesses compete for user information and third-party market share, while users balance trade-offs between information control, privacy concerns, and the benefits of information sharing. We find that when users cannot opt out of personal information tracking, digital businesses engage in intense competition for both information collection and pricing, particularly when privacy concerns are low. Conversely, when users can opt out, higher privacy concerns amplify the information advantage of high-level digital businesses, increasing competition and widening disparities in information collection level. Moreover, when privacy concerns are low and the marginal value of user information is high, introducing user information authorization models can expand the information market, boosting the profits of digital businesses. In this case, user control over personal information may reduce consumer surplus. When some anonymous users prohibit information tracking, the presence of double homing users leads the high-level digital business to reduce its information collection.","PeriodicalId":55161,"journal":{"name":"European Journal of Operational Research","volume":"75 1","pages":""},"PeriodicalIF":6.4,"publicationDate":"2025-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145009226","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Though e-tailers usually have a demand information advantage that can be known by the MNFs’ manufacturing divisions, interestingly, we note that due to a lack of cyber resilience, data transfer barriers between MNFs’ manufacturing and retailing divisions have widely inhibited intersectoral information transfer. Therefore, risk-averse retailing divisions may postpone orders to wait for the information, exposing them to a second-mover disadvantage. Intuitively, advanced intersectoral data transfer such as AI-enabled cybersecurity cloud platform is capable of facilitating the retailing division’s timely order based on demand information shared by the MNF, we observe that MNF’s tax-planning may be hampered under the Arm’s Length Principle, and tensions between horizontal (i.e., the e-tailer and the MNF’s retailing division) and vertical coordination may be exacerbated. Therefore, we study the MNF’s incentives to apply intersectoral data transfer based on a co-opetition game-theoretic model. We show that the retailing division’s preference varies with the tax disparity and its risk-averse degree. When tax disparity narrows, the <ce:italic>sourcing cost-saving effect</ce:italic> from postponed ordering allows the division to access demand information without incurring high costs. Establishing intersectoral data transfer is not always optimal for either the MNF or its retailing division. The MNF benefits when the tax disparity is high, whereas the retailing division should balance the information value against sourcing cost saving when deciding order timing.","PeriodicalId":55161,"journal":{"name":"European Journal of Operational Research","volume":"27 1","pages":""},"PeriodicalIF":6.4,"publicationDate":"2025-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145009230","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper investigates optimal strategies for firms to partially retrofit existing technologies and adjust production under various carbon policies, including scenarios without emission regulation, carbon taxation, and cap-and-trade systems. We propose a novel non-monotonic emission abatement cost function that captures both operational cost increases and resource savings associated with emissions reductions. By analyzing these three emissions regulation regimes, we demonstrate that the external pressures of carbon policies and the internal incentives for resource savings play a critical role in shaping a firm’s retrofitting and production decisions. Numerical experiments support these findings, highlighting the importance of maintaining stable carbon policies to facilitate effective emission reductions.","PeriodicalId":55161,"journal":{"name":"European Journal of Operational Research","volume":"13 1","pages":""},"PeriodicalIF":6.4,"publicationDate":"2025-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144924101","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Governments often set aside capacity for use during crises or opt to rely on third parties, such as the private sector. Both options, however, may not be viable, as the former is expensive and the latter is not reliable. To overcome this dilemma, we introduce a strategic disaster preparedness framework in which the government engages private suppliers by investing in a portion of their resources, in return for access when needed. The resources are maintained and used by suppliers in their routine operations unless required for an emergency. We introduce a Stackelberg game-theoretic model that captures the interaction between the government and private suppliers under a limited budget and characterize key structural properties of optimal disaster preparedness plans. These properties lead to single-level reformulations and efficient exact and approximation algorithms under certain conditions. We test the proposed models on a case study based on major disasters affecting Canada. Findings indicate that incorporating resource sharing into emergency preparedness planning leads to more than a 26% increase in social good or more than a 13% decrease in cost compared to traditional preparedness plans. The study underscores the value of the proposed approach for strategic disaster preparedness and provides important insights into public policy.","PeriodicalId":55161,"journal":{"name":"European Journal of Operational Research","volume":"26 1","pages":""},"PeriodicalIF":6.4,"publicationDate":"2025-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144923970","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Traditionally, these challenges are addressed using a sequential approach, where flights, aircraft, and cargo operations are reinstated step by step, leading to incompatibility and resource wastage. This research introduces a comprehensive strategy for integrated recovery of air cargo transportation under various abnormal scenarios, where both aircraft and cargo recovery are considered, and different transportation modes (e.g., freighter flights, belly flights, and trucks) are utilized. A novel string-based model is proposed to decompose and solve the integrated air cargo recovery problem. The model explores the complexities arising from multiple abnormal scenarios and considers cargo timeliness with different transportation modes (e.g., freighter flights, belly flights, and trucks), aligning the recovery process more closely with real-world operations. A heuristic-based column-and-row generation algorithm is proposed based on properties of the model. Moreover, a series of inequality constraints and integer processing mechanisms are designed, which significantly reduces the solution gap between mixed-integer-program model and linear relaxation of model. The performances of the proposed model and algorithms are shown in the experiments based on two real world datasets under four scenarios from the largest freighter airline company in China.","PeriodicalId":55161,"journal":{"name":"European Journal of Operational Research","volume":"38 1","pages":""},"PeriodicalIF":6.4,"publicationDate":"2025-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145009227","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The main goal of this paper is to facilitate interdisciplinary research between the Operations Research (OR) and quantum computing communities by helping OR scientists to build initial intuition for-, and offering them a hands-on gateway to quantum-powered methods in the context of discrete optimization. To this end, we consider three quantum-powered optimization approaches that make use of different types of quantum hardware available on the market. To illustrate these approaches, we solve three classical optimization problems: the Traveling Salesperson Problem, Weighted Maximum Cut, and Maximum Independent Set. With a general OR audience in mind, we attempt to provide an intuition behind each approach along with key references, describe the corresponding high-level workflow, and highlight crucial practical considerations. In particular, we emphasize the importance of problem formulations and device-specific configurations, and their impact on the amount of resources required for computation (where we focus on the number of qubits).

Each vehicle type has a different cost structure, payload capacity, and traveling range. The objective function minimizes the sum of the recharging (or refueling) cost, driver cost, fixed vehicle cost, and waiting cost for vehicles and drivers at recharging stations. While the transportation cost (including the recharging cost, driver cost, and vehicle cost) depends on the traveled distance, the recharging fee and waiting cost depend on the number of visits to recharging stations. We develop a mixed-integer linear programming formulation with preprocessing rules and also propose a relax-and-fix heuristic approach. The computational experiments are conducted over well-known CAB and TR data sets, and also a new German data set. The computational results evaluate the performance of the relax-and-fix heuristics and analyze the impact of varying fuel prices, limits on the use of vehicle types, different fleet compositions, different cost structures, and a hypothetical drone with a larger payload capacity and a longer flying range. Results show how the optimal fleet mix, in particular the use of electric vehicles and drones, and the optimal network vary around the world, as these depend on the geographic scope of the services, the distribution of nodes and arc lengths, and the relative costs for fuel (electricity or diesel).","PeriodicalId":55161,"journal":{"name":"European Journal of Operational Research","volume":"33 1","pages":""},"PeriodicalIF":6.4,"publicationDate":"2025-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145059658","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Decomposition-based evolutionary algorithms have received considerable attention as promising approaches for solving MOPs. However, most existing algorithms utilize the geometric structure of a single point and multiple directions to guide the evolutionary search, which limits their success in dealing with MOPs with irregular POFs. To overcome this limitation, this paper proposes an effective multiobjective evolutionary algorithm that leverages the geometric pattern of multiple reference points and a single direction, thereby preventing solutions from focusing on the same region of the POF to some extent. The algorithm is configured with a multiple reference points strategy that includes the generation and adjustment of reference points. The proposed algorithm is compared with existing state-of-the-art multiobjective evolutionary algorithms on benchmark MOPs with different types of POFs and four real-world MOPs. The experimental results demonstrate the effectiveness of the proposed algorithm.","PeriodicalId":55161,"journal":{"name":"European Journal of Operational Research","volume":"83 1","pages":""},"PeriodicalIF":6.4,"publicationDate":"2025-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145009095","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We consider a manufacturer (M) interacting with a retailer (R) and sharing economy platform (SEP), where M first negotiates a transfer payment to SEP for their PVO cooperation and, then, employs two wholesale price contracts for SEP and R to induce operational interactions. We obtain the following results. First, the PVO cooperation level affects SEP’s selection of a P2P or hybrid business model only if M’s marginal sales cost to SEP is moderate. Second, the negotiated transfer payment from M to SEP increases (is constant) in its cooperation level if M’s capital constraint on the transfer payment is non-binding (binding), but it is always strictly lower than the operational profit distribution from SEP to M. Third, without M’s capital constraint, PVO cooperation is always achievable and given a negotiated transfer payment for this cooperation, a higher PVO cooperation level benefits M, R, SEP, consumers, and the social planner, but PVO cooperation is attainable only if its level is capped within a reasonable range under a binding capital constraint for M. Therefore, M, R, and SEP should enhance PVO cooperation to improve overall supply chain efficiency. Moreover, the transfer payment for PVO cooperation does not satisfy the equal value principle typically applicable to arm’s length transactions, as the equity exchange between M and SEP must consider their ensuing operational interactions.","PeriodicalId":55161,"journal":{"name":"European Journal of Operational Research","volume":"41 1","pages":""},"PeriodicalIF":6.4,"publicationDate":"2025-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144924102","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
