In this study, we develop an optimization framework for designing strategic wildfire prevention policies that involve preemptive practices, such as electricity infrastructure hardening and public safety power shutoffs. Unlike existing studies that consider the pre- and post-wildfire event decisions separately, our approach captures in a unified framework the interaction between the preemptive strategic actions, the wildfire propagation, and the post-event operational decisions, such as the microgrid formation and the electricity distribution policies. To identify resilient strategies, we propose a worst-case-analysis approach that leverages a tri-level interdiction model focused on mitigating the worst possible disruption an uncontrolled wildfire can cause. To demonstrate the benefits of our framework, we conduct a case study based on the IEEE 14 bus and IEEE 30 bus systems, testing their performance under the proposed prevention policies for different initial settings and risk scenarios. We observe that the hardening strategies are fundamental for minimizing the unserved demand and the detrimental effect on the electricity infrastructure inflicted by wildfires. Furthermore, our results provide evidence that public safety power shutoffs are particularly beneficial in scenarios where the hardening budget is low. Similarly, we note that microgrids formed around distributed generators significantly improve the resiliency of electricity distribution systems in post-disaster scenarios.","PeriodicalId":55161,"journal":{"name":"European Journal of Operational Research","volume":"647 1","pages":""},"PeriodicalIF":6.4,"publicationDate":"2025-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144067541","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}

Georgiou, Georgios Tsaples, Emmanuel Thanassoulis","doi":"10.1016/j.ejor.2025.04.050","DOIUrl":"https://doi.org/10.1016/j.ejor.2025.04.050","url":null,"abstract":"This paper explores the extension of a modelling framework that integrates data envelopment analysis (DEA) and markov systems, into a two-stage setting. In a recent paper in EJOR, a single-stage DEA-markov hybrid model was introduced, establishing a research direction blending these seemingly distinct approaches to address the attainability problem in workforce planning. Markov systems are widely used in scenarios where a population system (e.g., staff profiles, patients with chronic conditions) begins the planning horizon in a specific state and aims to transition to a new state by the end of the horizon. Although it is common for this horizon to encompass multiple steps, this hybrid model considered attainability within a single-step horizon. In the current study, we investigate problems in two phases and integrate a network DEA approach with markovian population systems under various assumptions, resulting into new variations of the relevant models. The decision maker (DM) can specify potential future outcomes (e.g., personnel flows) in consecutive steps in time, and use DEA to identify feasible courses of action through convexity (or even use the second stage in a normative manner to identify optimal flows). The two-stage DEA model captures the DM’s relative preferences for future states and provides measures of efficacy of potential flows relative to the ultimate desired state. Consequently, the organization can plan interventions to enhance the probability of achieving some anticipated goal. The paper includes illustrations using data from workforce planning and concludes with a discussion on relevant issues in healthcare, circular economy and social radicalization.","PeriodicalId":55161,"journal":{"name":"European Journal of Operational Research","volume":"11 1","pages":""},"PeriodicalIF":6.4,"publicationDate":"2025-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143901838","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}

Variations in DMs’ backgrounds, expertise, and dynamic environmental interactions shape their psychological states, consequently affecting their information-processing strategies and potentially contributing to information cocoon effects. This study aims to develop a conflict-elimination framework that (1) evaluates DMs’ psychological states, (2) identifies the dual nature of information cocoon effects (ICEs) shaping their behaviors, and (3) formulates targeted conflict resolution strategies based on these insights. First, we employ a resilience model to quantify psychological resilience as an indicator of DMs’ psychological states. For highly resilient DMs — less susceptible to ICEs — a tailored conflict elimination strategy using a bi-level optimization model is introduced. For less resilient DMs — more prone to cocoon influences — we examine the conditions under which ICEs can obstruct or facilitate conflict resolution. We then design corresponding optimization models to harness these effects constructively. A numerical demonstration and sensitivity analysis confirm the proposed framework’s effectiveness. Our approach enhances decision-making efficiency and improves conflict resolution outcomes by aligning resolution strategies with DMs’ psychological states and the nature of their ICEs.","PeriodicalId":55161,"journal":{"name":"European Journal of Operational Research","volume":"16 1","pages":""},"PeriodicalIF":6.4,"publicationDate":"2025-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143901837","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 is the first to propose a method for dynamically adjusting productivity while considering both system degradation and product quality. We construct a dynamic programming model using optimal control theory to address both fixed maintenance cycles and the joint optimization of production and maintenance strategies. Our approach identifies optimal production strategies for various scenarios, showing that integrating product quality considerations with productivity and degradation significantly enhances overall outcomes. Extensive numerical studies validate our results, demonstrating that this comprehensive optimization scheme not only increases production system revenue but also reduces maintenance costs as well as product defects. By accounting for the dual impact of productivity on system degradation and product quality, this research provides a more holistic and practical strategy for maximizing manufacturing revenue and product reliability. The findings offer significant theoretical and practical value, guiding enterprises toward achieving a balance between high productivity, system longevity, and product quality.","PeriodicalId":55161,"journal":{"name":"European Journal of Operational Research","volume":"1 1","pages":""},"PeriodicalIF":6.4,"publicationDate":"2025-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143932503","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}
