建筑业正迈入智能建造引领、数字化全面驱动的新纪元，项目经理的多任务处理复杂程度显著增加。心理韧性作为应对复杂项目挑战的关键能力，对于提升多任务处理绩效尤为重要。本文基于多任务模拟实验（multi-attribute task battery，MATB），结合奖惩机制与任务难度两个指标，构建了数字场景下的四种情景，探究项目经理心理韧性在不同任务复杂度及奖惩机制下，对多任务处理绩效的影响机理。结果表明：具有高心理韧性的项目经理在奖励机制下表现最佳，而低心理韧性的项目经理在面对高任务难度和惩罚机制时则表现显著下降。且奖惩机制与心理韧性之间存在交互效应，这两者共同对多任务处理绩效产生了显著影响。研究强调了心理韧性在多任务处理中的重要作用，为项目经理在复杂多变的数字场景下有效应对压力挑战提供了科学策略，以期提升多任务处理能力和项目绩效管理水平。

To resolve the problem of the low management capacity of highway preventive maintenance (HPM), this paper identified and evaluated the major HPM management factors to improve management effectiveness and achieve sustainable highway development. The study conducted a literature review and exploratory factor analysis (EFA) to identify the major HPM management factors. Social network analysis (SNA) was used to distinguish the degree of importance of these factors. A system dynamics (SD) model was developed to explore their patterns of influence. The research identified six dimensions of HPM management, including the management system, management resources, management cognition, management decisions, management technology, and external conditions, along with 26 major management factors. Moreover, information acquisition, system perfection, etc., are key factors; system execution, manager capability, etc., are hub factors; and route selection, machinery allocation, etc., are non-key factors. These factors have a positive impact on HPM management, leading to an upward trend in management effectiveness. The main innovation provided a hybrid and comprehensive approach to identify and evaluate the major management factors for effective HPM. This study can guide managers in developing effective HPM plans, allocating resources more efficiently, improving the overall quality of highway maintenance and forming a sustainable transportation system.

This research endeavors to delve comprehensively into the ramifications of behavioral guidance policies pertaining to construction waste resource utilization (CWRU) on the behavioral awareness and attitudes of Chinese construction contractors. The implicit attitudes of 98 construction contractor workers toward construction waste collection, sorting, and reuse were quantitatively assessed by simulating different types of behavior-guided policies using the External Affective Simon Task (EAST) method with unconscious reaction time as an indicator. At the same time, the questionnaire survey was combined to collect and analyze the scores of these workers’ exogenous attitudes toward CWRU, with a view to revealing the contractors’ intrinsic behavioral awareness and exogenous attitudinal tendencies. The study reveals that economic incentive behavioral guidance policies are pivotal in fostering the collection, sorting, and reuse of construction waste. Furthermore, it novelly uncovers the distinct advantages of laws and regulations frameworks in safeguarding the fundamental aspects of construction waste collection. Notably, publicity and education behavioral policies emerge as a cornerstone in elevating the significance of construction waste collection and sorting, highlighting the cruciality of enhancing public awareness and knowledge to propel CWRU. The results of the study not only provide empirical evidence to understand the inherent attitudes of construction contractor workers toward CWRU behavior but also provide practical support for future policymakers. By advocating for economic incentives, strengthening regulations, and leading education, the multi-pronged approach promotes China’s CWRU accelerates the green transformation of the construction industry.

Transmission lines are often located in complex environments and are susceptible to the presence of foreign objects. Failure to promptly address these objects can result in accidents, including short circuits and fires. Existing foreign object detection networks face several challenges, such as high levels of memory consumption, slow detection speeds, and susceptibility to background interference. To address these issues, this paper proposes a lightweight detection network based on deep learning, namely YOLOv5 with an improved version of CSPDarknet and a Swin Transformer (YOLOv5-IC-ST). YOLOv5-IC-ST was developed by incorporating the Swin Transformer into YOLOv5, thereby reducing the impact of background information on the model. Furthermore, the improved CSPDarknet (IC) enhances the model’s feature-extraction capability while reducing the number of parameters. To evaluate the model’s performance, a dataset specific to foreign objects on transmission lines was constructed. The experimental results demonstrate that compared to other single-stage networks such as YOLOv4, YOLOv5, and YOLOv7, YOLOv5-IC-ST achieves superior detection results, with a mean average precision (mAP) of 98.4%, a detection speed of 92.8 frames per second (FPS), and a compact model size of 10.3 MB. These findings highlight that the proposed network is well suited for deployment on embedded devices such as UAVs.

As the complexity, breadth of expertise and number of agents involved in megaprojects grow, collaborative innovation models become invaluable for helping to achieve sustainable project development. On this basis, the purpose of this study is to explore the innovation output mechanisms used for collaborative innovation in megaproject (CIMP) systems by the agent-based modelling (ABM) approach, and to promote the efficiency and effectiveness of organisational collaborative innovation through variable controls. A multi-agent simulation CIMP model was developed using the NetLogo tool. The model encompasses the behavioural factors and interaction rules that affect organisational CIMP. Four simulations were conducted, and the results showed that (1) the innovation environment, including policy environment, cultural climate, and engineering demand, has a positive effect on the output rate of CIMP; (2) a larger scale of innovative network organisation accelerates innovation output; (3) innovative organisations must avoid enforcing high standards for cooperation, communication, and recognition abilities when selecting partner organisations; (4) innovative organisations’ ability to absorb technology, information, and knowledge is positively related to output, while an increase in behavioural costs reduces the scale of innovative network organisations, thereby affecting their output. This study developed its CIMP theory from the perspective of organisational behaviour. The findings are expected to provide methodological and practical guidance for the selection of innovation agents, behavioural patterns, and for guaranteeing efficient innovation in collaborative megaproject organisations.

Building information modeling (BIM) is evolving as a digital infrastructure model for innovation in the construction field. The innovation-enabling potential of BIM has been highly neglected in the literature. This study explores the innovative potential of BIM, specifically its value in enabling construction innovation (CI). Through reflective research and a literature review, the relationship between BIM and CI is redefined, BIM-CI’s value spectrum and underlying mechanisms are mapped and their required resources and activities are illustrated. The results indicate that different BIM applications provide various proinnovation environments wherein CI may flourish. Extra attention should be paid to BIM-enabled systematic collaborative innovation and digital innovation ecosystems with BIM as the core infrastructure that integrates the physical space with cyberspace to accelerate radical innovation. This study extends BIM management research by considering digital innovation and providing a new perspective for CI management theory and practice. The results will provide academics with a solid point of departure for developing relevant research and serve as a reference for practitioners who intend to utilize BIM for efficient innovation in construction projects.

This paper aims to systematically analyze the reasons for the differences in the relationship between transformational leadership (TL) and project success and apply meta‐analysis to summarize which dimensions of TL are the main driving forces for project success. Adopting the meta‐analysis approach, we investigated 31 independent studies (N = 6475) and studied the theoretical moderators of this relationship from the perspectives of mediating variables, cultural background, and document type to test whether the moderating effects can explain the inconsistent research results. The results reveal that TL positively affects project success and leadership charm is the primary driver of TL. Also, the existence of a mediating mechanism has a more significant impact on the success of the leading project. Meanwhile, compared with project construction under the Western cultural background, countries with Eastern culture are more inclined to use a people‐oriented philosophy for project management to promote project success. This research provides an empirical perspective to help project leaders select management talents, regulate leaders’ words and deeds, and cultivate technical and soft leadership skills. Besides, this paper proposes a unique and nuanced view of the relationship between TL and project success, enhancing people’s understanding of the TL’s role in influencing project success.
