由于区块链技术的发展,许多传统应用程序得以改进。其中一项服务是不可否认性,在这种服务中,通信过程中的参与者不能否认他们的参与。由于不可否认协议的脆弱性,通信中的一方当事人往往可以规避不可否认规则,获取预期信息,从而损害另一方当事人利益,造成不良影响。本文利用概率模型检测技术对该协议的公平性保证进行定量研究。利用概率时间自动机对协议建模,并验证概率计算树逻辑中指定的属性,来衡量协议的公平性。此外,提出为协议相关参数选择合适值的建议,以获取一定程度的公平,从而回答了另一个问题:对于一定程度的公平性度量ε,如何指定协议参数以确保公平性?

Aircraft ground movement plays a key role in improving airport efficiency, as it acts as a link to all other ground operations. Finding novel approaches to coordinate the movements of a fleet of aircraft at an airport in order to improve system resilience to disruptions with increasing autonomy is at the center of many key studies for airport airside operations. Moreover, autonomous taxiing is envisioned as a key component in future digitalized airports. However, state-of-the-art routing and scheduling algorithms for airport ground movements do not consider high-fidelity aircraft models at both the proactive and reactive planning phases. The majority of such algorithms do not actively seek to optimize fuel efficiency and reduce harmful greenhouse gas emissions. This paper proposes a new approach for generating efficient four-dimensional trajectories (4DTs) on the basis of a high-fidelity aircraft model and gainscheduling control strategy. Working in conjunction with a routing and scheduling algorithm that determines the taxi route, waypoints, and time deadlines, the proposed approach generates fuel-efficient 4DTs in real time, while respecting operational constraints. The proposed approach can be used in two contexts: ① as a reactive decision support tool to generate new trajectories that can resolve unprecedented events; and ② as an autopilot system for both partial and fully autonomous taxiing. The proposed methodology is realistic and simple to implement. Moreover, simulation studies show that the proposed approach is capable of providing an up to 11% reduction in the fuel consumed during the taxiing of a large Boeing 747 jumbo jet.
