    Congestion Games with Heterogeneous Valuations: An Optimal Transport Approach

    In emerging urban mobility and logistics applications, such as advanced air mobility, electric vehicle charging, and shared service systems, agents with heterogeneous valuations choose among multiple destinations while sharing congested network resources. However, existing congestion game and resource allocation models do not simultaneously capture heterogeneous destination preferences and aggregate congestion externalities. We introduce a new nonatomic congestion game framework in which agents are endowed with heterogeneous destination valuations modeled by a measure space. We characterize Nash equilibria and social optima in this setting and show that both admit finite-dimensional representations in terms of threshold vectors and dual potentials. These structures induce a partition of the valuation space that determines agents' destination choices. Our analysis leverages Kantorovich duality from optimal transport theory and provides a new geometric perspective on congestion games with heterogeneous valuations.（预印本；同行评审状态请核对原文。）

    A Scenario-Based Continuous-Time Markov Framework for Preliminary Safety Screening of eVTOL Operations Under Climate, Battery, Power-Supply and Diagnostic Uncertainty

    This study examines the development of urban air mobility, which requires the creation of vertiports capable of ensuring the safe operation of electric vertical takeoff and landing (eVTOL) systems. Key operational constraints include unstable power supply, external climatic conditions, and reliance on battery systems. This study aims to develop a risk-based model for vertiport planning those accounts for the stochastic nature of eVTOL operational safety. A continuous-time Markov model incorporating nominal operational characteristics, system constraints, and transitions into emergency and catastrophic flight modes is proposed. State transitions within the model are primarily driven by climatic indicators, power supply reliability, battery parameters, maintenance quality, and diagnostic coverage. To interpret the low probabilities of transitioning to a catastrophic mode, this study introduces a safety index (integrated safety index), which facilitates the comparison of various operational scenarios and regulatory maturity levels. The practical importance of the research lies in applying the proposed model to precisely select vertiport locations; assess energy infrastructure requirements; and organize onboard monitoring, robotic preflight inspection systems, and decision support systems. The results demonstrate that eVTOL operational safety is assessed not only through spatial and infrastructure metrics but also through an integrated indicator encompassing power supply, climate, battery degradation, diagnostics, and hardware–software reliability of the entire vertiport system

    A hybrid evaluation framework for eVTOL deployment in the low-altitude economy: usability, risk, and strategic implications

    Abstract Amid the rapid global emergence of the low-altitude economy (LAE), electric vertical take-off and landing (eVTOL) aircraft, recognized as a key technology for urban air mobility (UAM), face multifaceted challenges in terms of usability and risk evaluation. Existing assessment approaches are generally limited by their inadequate capacity to handle uncertainty, insufficient identification of causal relationships, and fragmented indicator systems, thus hindering comprehensive decision support for eVTOL deployment. To address these issues, this study proposes a multi-stage hybrid multi-criteria decision-making (MCDM) framework that integrates neutrosophic fuzzy sets (NFS), the weighted influence non-linear gauge system (WINGS), and interpretive structural modeling (ISM). The framework first employs NFS to quantitatively represent experts’ uncertain cognitive evaluations, then applies the WINGS model to capture the non-linear interaction intensity and centrality among factors, and finally incorporates ISM to uncover multi-level causal pathways. This integrated approach enables a closed-loop decision support process encompassing evaluation, diagnosis, and optimization. An empirical analysis focusing on eVTOL applications in public service scenarios identifies critical structural barriers such as infrastructure development gaps, policy lag, and market adaptation challenges. Corresponding systematic optimization strategies are proposed. The results demonstrate that the proposed model exhibits strong robustness and interpretability in managing fuzzy information and modeling
