This study addresses a critical gap at the intersection of omnichannel logistics and circular economy integration by proposing a unified, resilience-oriented optimization model. The integration of these two paradigms is essential: while omnichannel networks inherently involve complex bidirectional flows, circular economy strategies provide built-in redundancy and resource recirculation capabilities. However, existing literature largely overlooks their combined potential for proactive disruption preparedness. To bridge this gap, we develop a mathematical model that simultaneously optimizes forward logistics (including facility siting, inventory allocation, cross-docking, and multimodal transport) and reverse flows (returns handling, material recovery, and recycling). Circular economy decisions are modeled as endogenous variables that dynamically adapt to disruption scenarios, allowing real-time reconfiguration of fulfillment strategies across online, in-store, and humanitarian channels. The model is validated through a real-world application in a national-scale canned food supply network. Results suggest the model maintains performance across varying disruption intensities and operational scales, revealing key trade-offs between profit efficiency, environmental impact, and service responsiveness. The findings highlight that resilience is most effectively achieved through anticipatory strategies such as capacity flexibility and fulfillment agility, rather than through reactive or compliance-driven measures alone. This study offers a scalable decision-support tool for practitioners and policymakers seeking to design sustainable, adaptive, and disruption-resilient omnichannel supply chains.</div></div>","PeriodicalId":19529,"journal":{"name":"Omega-international Journal of Management Science","volume":"141 ","pages":"Article 103466"},"PeriodicalIF":7.2,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145840662","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}

Building on these industry insights, we investigate how the introduction of a new fare product interacts with load factor constraints and the misestimation of valuation differences between fare products, ultimately shaping consumer responses. In the empirical component of the study, we utilize transaction-level data from a major airline to validate the model’s predictions and derive additional managerial insights. Our analysis reveals a strong association between load factor levels and customer purchasing patterns. Moreover, the accurate estimation of the valuation gap across fare products proves to be a crucial determinant of consumer behavior.

This paper develops a two-period pricing model in which two firms, differing in product quality, investigate the impact of behavior-based pricing (BBP) on firms with varying quality levels when they possess imperfect customer recognition capability. We find, first, that imperfect customer recognition capability causes different effects on price in each period for firms of different quality, depending on the level of product quality differentiation. Second, quality advantages do not always lead to more markets for high-quality firms; low-quality firms are also in a position to gain more markets. Third, due to firms’ customer recognition capability and quality differentiation, when both firms adopt BBP, they will both achieve higher profits and reach a ”win–win” situation. Conversely, if only one firm adopts BBP, it will result in reduced profitability for both firms, leading to a ”lose–lose” scenario. Finally, we have examined consumer surplus and social welfare, and the findings provide a theoretical foundation and policy recommendations for governments to develop regulatory measures against price discrimination in the digital economy era.</div></div>","PeriodicalId":19529,"journal":{"name":"Omega-international Journal of Management Science","volume":"141 ","pages":"Article 103488"},"PeriodicalIF":7.2,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145884133","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}

Initially, we analyze the optimal upgrade strategies for firms, distinguishing between those with no/partial/comprehensive user ecology. Subsequently, we carry out the analysis of the optimal design for the user ecology. Moreover, we explore the effectiveness of strategically disposing of partial ecology. The primary findings illustrate the importance of upgrade costs in scenarios without user ecology, where the line-extension strategy dominants the replacement strategy. In the presence of user ecology, we elucidate the demand aggregation effect that may hinder users from buying a new-generation product. Consequently, the replacement strategy emerges as optimal when product differentiation is low. Intriguingly, the existence of user ecology may impede firms from introducing new-generation products. The construction of user ecology provides advantages for firms in emerging markets but may be detrimental in mature markets. Furthermore, our results highlight that comprehensive user ecology may compromise firm’s profit. Disposing of partial ecology strategically can enhance performance, especially when both network effect and product differentiation are low.

To deal with this risk, companies may adopt specific service level targets to satisfy at least a certain proportion of their demand while considering operational constraints and minimizing the total cost. In this study we address the stochastic production routing problem (PRP) with adaptive routing and service level constraints. The PRP unifies the production, inventory and routing decisions into an integrated problem aimed at improving coordination across different parts of the system. We consider four different types of service levels, where each type uses a specific metric based on assumptions aligning with the needs of the company. These metrics encompass aspects such as the occurrence of stockouts or allowed ratios of backlogs or backorders to average demand. A two-stage stochastic formulation is proposed for each type of service level. Setup decisions are made in the first stage, and production, inventory, and routing decisions are adapted after demand realization. Considering routing decisions in the second stage increases flexibility while lowering overall costs. However, the resulting optimization problem is more challenging to solve than the case where routing decisions are made in the first stage. To address this issue, we introduce an iterative matheuristic algorithm designed to yield high-quality solutions within a reasonable computation time. The effectiveness of the proposed heuristic algorithm is demonstrated through extensive experiments, highlighting its potential to assist companies in managing demand uncertainty and enhancing operational efficiency.</div></div>","PeriodicalId":19529,"journal":{"name":"Omega-international Journal of Management Science","volume":"141 ","pages":"Article 103496"},"PeriodicalIF":7.2,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145840660","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 study proposes a novel hierarchical adaptive robust optimization framework for the robust infrastructure design for CCUS under carbon emission uncertainty. Methodologically, the framework integrates strategic hub location with robust infrastructure and flow planning through a bilevel decomposition: an upper-level K-means++ clustering-based heuristic endogenously identifies hub configurations, while a lower-level adaptive robust model optimizes pipeline establishment, storage selection, and transport flows. To ensure computational tractability, we develop an Enhanced Column-and-Constraint Generation algorithm incorporating a modified outer approximation method. We validate the framework using realistic case studies, yielding several insights. First, emission uncertainty plays only a subordinate role in strategic hub selection, as both hub configurations and major pipelines remain stable across uncertainty budgets. This finding suggests that planners can make investment decisions with confidence. Second, storage choices are highly sensitive to the interplay between oil prices and sink-specific subsidies, underscoring the need for flexible and diversified storage portfolios. Third, dynamic subsidies that adjust based on oil market conditions can effectively shift storage toward saline aquifers at modest fiscal costs. This proposed framework thus provides a decision-support tool for CCUS planning, offers quantitative evidence for policy design, and enables CCUS planning decisions to align with societal carbon neutrality goals.</div></div>","PeriodicalId":19529,"journal":{"name":"Omega-international Journal of Management Science","volume":"141 ","pages":"Article 103512"},"PeriodicalIF":7.2,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145976938","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}

However, since the resources can process several jobs simultaneously, a cumulative job shop problem arises. The primary objective is to maximize the number of accepted jobs from a job pool with given release and due dates. The secondary objective is to minimize delays in job processing, i.e., the jobs’ waiting times, as earlier completion of jobs allows for faster feedback and refinement of future crop variants, ultimately improving the overall testing and development process.

We also show how it can be solved with a flexible hierarchical approach, even for very large problem instances.
