    Risk evaluation for the task transfer of an aircraft maintenance program based on a multielement connection number

    Tao LIUZhibo SHIHuifen DONGJie BAI...
    16-31页
    查看更多>>摘要：This paper proposes a framework for evaluating the efficacy and suitability of maintenance programs with a focus on quantitative risk assessment in the domain of aircraft maintenance task transfer.The analysis is anchored in the principles of Maintenance Steering Group-3(MSG-3)logic decision paradigms.The paper advances a holistic risk assessment index architecture tailored for the task transfer of maintenance programs.Utilizing the analytic network process(ANP),the study quantifies the weight interrelationships among diverse variables,incorporating expert-elicited subjective weighting.A multielement connection number-based evaluative model is employed to characterize decision-specific data,thereby facilitating the quantification of task transfer-associated risk through the appraisal of set-pair potentials.Moreover,the paper conducts a temporal risk trend analysis founded on partial connection numbers of varying orders.This analytical construct serves to streamline the process of risk assessment pertinent to maintenance program task transfer.The empirical component of this research,exemplified through a case study of the Boeing 737NG aircraft maintenance program,corroborates the methodological robustness and pragmatic applicability of the proposed framework in the quantification and analysis of mission transfer risk.

    Urban rail transit disruption management:Research progress and future directions

    Lebing WANGJian Gang JINLijun SUNDer-Horng LEE...
    79-91页
    查看更多>>摘要：Urban rail transit(URT)disruptions present considerable challenges due to several factors:ⅰ)a high probability of occurrence,arising from facility failures,disasters,and vandalism;ⅱ)substantial negative effects,notably the delay of numerous passengers;ⅲ)an escalating frequency,attributable to the gradual aging of facilities;and iv)severe penalties,including substantial fines for abnormal operation.This article systematically reviews URT disruption management literature from the past decade,categorizing it into pre-disruption and post-disrup-tion measures.The pre-disruption research focuses on reducing the effects of disruptions through network analy-sis,passenger behavior analysis,resource allocation for protection and backup,and enhancing system resilience.Conversely,post-disruption research concentrates on restoring normal operations through train rescheduling and bus bridging services.The review reveals that while post-disruption strategies are thoroughly explored,pre-disruption research is predominantly analytical,with a scarcity of practical pre-emptive solutions.Moreover,future research should focus more on increasing the interchangeability of transport modes,reinforcing redundancy relationships between URT lines,and innovating post-disruption strategies.

    A dynamic speed guidance method at on-ramp merging areas of urban expressway considering driving styles

    Haoran LIYunpeng LUYaqiu LIJunyi ZHANG...
    92-106页
    查看更多>>摘要：Dynamic speed guidance for vehicles in on-ramp merging zones is instrumental in alleviating traffic congestion on urban expressways.To enhance compliance with recommended speeds,the development of a dynamic speed-guidance mechanism that accounts for heterogeneity in human driving styles is pivotal.Utilizing intelligent connected technologies that provide real-time vehicular data in these merging locales,this study proposes such a guidance system.Initially,we integrate a multi-agent consensus algorithm into a multi-vehicle framework oper-ating on both the mainline and the ramp,thereby facilitating harmonized speed and spacing strategies.Subsequently,we conduct an analysis of the behavioral traits inherent to drivers of varied styles to refine speed planning in a more efficient and reliable manner.Lastly,we investigate a closed-loop feedback approach for speed guidance that incorporates the driver's execution rate,thereby enabling dynamic recalibration of advised speeds and ensuring fluid vehicular integration into the mainline.Empirical results substantiate that a dynamic speed guidance system incor-porating driving styles offers effective support for human drivers in seamless mainline merging.

    CAV driving safety monitoring and warning via V2X-based edge computing system

    Cheng CHANGJiawei ZHANGKunpeng ZHANGYichen ZHENG...
    107-127页
    查看更多>>摘要：Driving safety and accident prevention are attracting increasing global interest.Current safety moni-toring systems often face challenges such as limited spatiotemporal coverage and accuracy,leading to delays in alerting drivers about potential hazards.This study explores the use of edge computing for monitoring vehicle motion and issuing accident warnings,such as lane depar-tures and vehicle collisions.Unlike traditional systems that depend on data from single vehicles,the cooperative vehicle-infrastructure system collects data directly from connected and automated vehicles(CAVs)via vehicle-to-everything communication.This approach facilitates a comprehensive assessment of each vehicle's risk.We propose algorithms and specific data structures for evalu-ating accident risks associated with different CAVs.Furthermore,we examine the prerequisites for data accuracy and transmission delay to enhance the safety of CAV driv-ing.The efficacy of this framework is validated through both simulated and real-world road tests,proving its utility in diverse driving conditions.

    A bilateral heterogeneous graph model for interpretable job recommendation considering both reciprocity and competition

    Xiaowei SHIQiang WEIGuoqing CHEN
    128-142页
    查看更多>>摘要：Amidst the inefficiencies of traditional job-seeking approaches in the recruitment ecosystem,the importance of automated job recommendation systems has been magnified.However,existing models optimized to maximize user clicks for general product recommendations prove inept in addressing the unique challenges of job recommendation,namely reciprocity and competition.Moreover,sparse data on online recruitment platforms can further negatively impact the performance of existing job recommendation algorithms.To counteract these limita-tions,we propose a bilateral heterogeneous graph-based competition iteration model.This model comprises three integral components:1)two bilateral heterogeneous graphs for capturing multi-source information from people and jobs and alleviating data sparsity,2)fusion strategies for synthesizing attributes and preferences to produce mutually beneficial job matches,and 3)a competition-enhancing strategy for dispersing competition realized through a two-stage optimization algorithm.Augmented by granular attention mechanisms for enhanced inter-pretability,the model's efficacy,competition dispersion,and interpretability are validated through rigorous empirical evaluations on a real-world recruitment platform.

    Knowledge enhanced graph inference network based entity-relation extraction and knowledge graph construction for industrial domain

    Zhulin HANJian WANG
    143-158页
    查看更多>>摘要：With the escalating complexity in production scenarios,vast amounts of production information are retained within enterprises in the industrial domain.Probing questions of how to meticulously excavate value from complex document information and establish coherent information links arise.In this work,we present a framework for knowledge graph construction in the industrial domain,predicated on knowledge-enhanced document-level entity and relation extraction.This approach alleviates the shortage of annotated data in the industrial domain and models the interplay of industrial documents.To augment the accuracy of named entity recognition,domain-specific knowledge is incorporated into the initialization of the word embedding matrix within the bidirectional long short-term memory conditional random field(BiLSTM-CRF)framework.For relation extraction,this paper introduces the knowledge-enhanced graph inference(KEGI)network,a pioneering method designed for long paragraphs in the industrial domain.This method discerns intricate interactions among entities by constructing a document graph and innovatively integrates knowledge representation into both node construction and path inference through TransR.On the application stratum,BiLSTM-CRF and KEGI are utilized to craft a knowledge graph from a knowledge representation model and Chinese fault reports for a steel production line,specifically SPOnto and SPFRDoc.The F1 value for entity and relation extraction has been enhanced by 2％to 6％.The quality of the extracted knowledge graph complies with the requirements of real-world production environment applications.The results demonstrate that KEGI can profoundly delve into production reports,extracting a wealth of knowledge and patterns,thereby providing a comprehensive solution for production management.
